# The best free GitHub repos for non-coders, and the scan to run first Source: https://aaronmakelky.com/blog/best-free-github-repos Last updated: 2026-11-04 Ryan Doser and I went through 16 free GitHub repos on AI Rabbit Holes, from SEO and PR to video and writing. Here's what each one does, which ones I use, and the safety check to run before you fork any of them. November 4, 2026 · 16 min read AI Rabbit Holes · GitHub · Open Source · Claude Skills · SEO · HyperFrames · AI Tools [All my AI Rabbit Holes episodes](/ai-rabbit-holes) ![](https://i.ytimg.com/vi/HNyKJwpsbpU/hqdefault.jpg) Ryan Doser and me on AI Rabbit Holes: the free GitHub repos we actually use. Here's the single best thing you can do to adapt. If you don't have a GitHub account, go make a free one. If you do, keep a list, or give this post to your agents and have them star some of these. I see GitHub as my gateway drug to all this AI coding and building. About a year ago, when I got sucked in, GitHub was the vehicle that took me there, more than ChatGPT or Claude was. I went through the best free GitHub repos with [Ryan Doser](https://ryandoser.com/) on [AI Rabbit Holes](https://www.youtube.com/watch?v=HNyKJwpsbpU), recorded October 29, 2026. Our episodes go up on [Ryan's YouTube channel](https://www.youtube.com/@RyanDoserAI), and Ryan has his own write-up, [the best GitHub repos for marketing](https://ryandoser.com/best-github-repos-for-marketing/). If GitHub is new to you, start with our last episode, [GitHub for marketers](/blog/github-for-marketers). [![Table of the 16 free GitHub repos from the episode and what each one is for. Ryan's picks: his free Claude skills, Google Workspace CLI, Anthropic skills, last30days, Firecrawl, a Search Console MCP, OpenSEO, Newsjack, HyperFrames, and Postiz. Aaron's picks: AI Writing Audit, Herdr, Cloudflare OS, Whisper, Matt Pocock's skills, and DESIGN.md.](/images/blog/best-free-github-repos/repo-list.png)](/images/blog/best-free-github-repos/repo-list.png) Every repo from the episode, with who picked it. ## The anti-AI crowd [Watch this part of the episode (3:32)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=212s) Ryan opened with a post of his that went semi-viral: people can complain all they want, but it will not end well for the anti-AI crowd. He means careers and taking care of your family, not the end of humanity. His example is Moneyball: adapt or die. Here's my example. You have an advantage if you use these tools right now, if you reinvent your workflows and learn new skills that used to be very inaccessible to non-technical people, like GitHub. Now think of the advantage the next generation has if they're learning from people like us at home, let alone on the internet. Compare that to the Luddites who want to burn down the factory because it'll take their jobs. If that's your teacher or your parent, one generation from now you're already a lost cause. You'd better hope there's some kind of universal basic income, and I don't know too many people confident enough in the government for that. I certainly am not. I want my kids to learn those skills. What would you tell farmers when the tractor came out? Horses aren't bad, but learn it. ## Start with a free GitHub account [Watch this part of the episode (8:50)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=530s) Ryan keeps every website and landing page he has in a private GitHub repo, including ryandoser.com and the pages he builds for clients' paid ad campaigns. His ChatGPT Dots assistant backs up its SOPs, daily logs, and call transcripts to a private repo too. The coolest thing about AI is your microwave can't tell you how to use it, but your AI tool can tell you how to use itself and tools like GitHub. The biggest thing I hear from people is, I don't know the vocabulary. It says PR merged. What does PR stand for? What does merge mean? 1. Give your AI tool of choice the GitHub connector. You log in once, and it's good. 2. Tell it you're not a developer. Use plain English that you'll know as a marketer, a teacher, a nurse, whatever your skill set is. 3. Any time it slips into jargon, say, explain what a PR is, or explain what merge did. I didn't know this about GitHub at first, and it makes me feel dumb. It's version control. A Google Doc says Ryan changed this sentence five minutes ago, and it's highlighted. That's all Git is. If you broke something, it's easy to undo it or see who broke it. When you update your agent every day and break something, you can go back to yesterday's version, like a backup of your computer. Ask your AI tool to explain this stuff, and you'll have it down in two days. ## Scan a repo before you use it [Watch this part of the episode (13:15)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=795s) Ryan's way to use any public repo: copy its URL, paste it into Claude, ChatGPT, Claude Code, or Codex, and say implement this. It'll walk you through it step by step. But be careful. Public repos can hold prompt injections and malicious files, so have your agent scan the repo first. I asked him for the exact prompt, so I could practice it. His answer: tell it to analyze the entire GitHub repository and look for any malicious files, or any sign it could take your API keys or steal your data. Be broad. Ask it to check whether the repo will do anything malicious to your existing setup. I've seen that in GitHub repos, where the repo gives instructions and your AI agent, at least the older models, would follow them and put in something that syncs all your data with them. ## Ryan's free skills, and star the ones you want [Watch this part of the episode (13:44)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=824s) Ryan gives away 15 of his skills for free in [free-claude-skills](https://github.com/rdoser13/free-claude-skills): SEO, keyword research, CRO, landing pages, and anti-slop checks from his 10 plus years in marketing. A skill is basically an SOP, a standard operating procedure for one task. Another reason to get a GitHub account: starring a repo is like a bookmark that doesn't have to live in your browser. You don't have to put it in Notion. If you see Ryan's and go, I want to use that, click the star. You'll always be able to find it, and it's easy to search for. Then tell your AI tool, use GitHub to look at my starred repos. Those are things we can use for marketing. Ryan's warning on stars: they might be the new Reddit upvotes, in terms of how easily they get manipulated. ## Google Workspace CLI [Watch this part of the episode (15:16)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=916s) Ryan works in VS Code with Claude Code and Codex, where there's no one-click Google Drive connector like the Claude and ChatGPT web apps have. The [Google Workspace CLI](https://github.com/googleworkspace/cli) is his workaround, and it's the official one, not a third party. He keeps short-form videos in Drive folders, pastes a folder URL into VS Code, and has Claude Code analyze the transcripts, write captions, and schedule the posts. ## Anthropic's skills, and one for teachers [Watch this part of the episode (16:40)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1000s) Anthropic, who makes Claude, has its own free [skills repo](https://github.com/anthropics/skills). Ryan uses the front-end design skill and the skill creator, which builds new skills with best practices. Speaking of school, Anthropic also released [a skills repo for K-12 teachers](https://github.com/anthropics/k12-teacher-skills). If you're an educator or a principal, it's things specifically for teachers. Claude can already do pretty good front-end design, but a skill gives it a list of instructions with a more narrow focus than if you opened a chat and said, hey Claude, design a landing page. It's almost like steps or procedures in plain text. [![The anthropics/k12-teacher-skills repository on GitHub, titled Agent Skills for K-12 Teachers, listing four skills: lesson plan creation, lesson differentiation, lesson prep, and a check for understanding](/images/blog/best-free-github-repos/k12-teacher-skills-repo.jpg)](/images/blog/best-free-github-repos/k12-teacher-skills-repo.jpg) Anthropic's K-12 teacher skills. More on that side of things in [AI in schools](/ai-in-schools). Use people's skills, but fork them. They're free and public. Take Ryan's skill repo with 15 things in it. I might really like what his does with landing pages, but I'll add my own to it. Tell your agent, copy Ryan's thing, add this on top of it, and put it in my GitHub. You can make it private. I'm a big fan of customizing, because you're not going to want everything somebody does. Skills are amazing for inspiration, for I didn't know it could do this. Now make it your own. ## last30days [Watch this part of the episode (18:17)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1097s) [last30days](https://github.com/mvanhorn/last30days-skill) is a good news one. Say there's a topic. I worked on a team that used this as part of our daily routine: what's the internet saying about Claude, AI, data centers, what's new in the news. It can search Reddit, Twitter, and YouTube. You need API keys for some of the sources, but a lot of it's free. It's like a pulse check on the internet. [![The last30days-skill repository on GitHub, an AI agent skill that researches any topic across Reddit, X, YouTube, Hacker News, Polymarket, and the web, with its logo and a GitHub Trending repository of the day badge](/images/blog/best-free-github-repos/last30days-repo.jpg)](/images/blog/best-free-github-repos/last30days-repo.jpg) last30days searches the last month of Reddit, X, YouTube, and the web on any topic. ## Firecrawl for web scraping [Watch this part of the episode (19:27)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1167s) Ryan calls [Firecrawl](https://github.com/firecrawl/firecrawl) an advanced web scraper. WebFetch is the default scraper Claude uses, and scraping is a constant battle between websites blocking scrapers and scrapers finding workarounds. In his experience, Firecrawl gets through more often, and it has a generous free plan. ## The Search Console MCP [Watch this part of the episode (20:15)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1215s) Ryan uses [this Google Search Console MCP](https://github.com/Suganthan-Mohanadasan/Suganthans-GSC-MCP) every day, for ryandoser.com and his SEO clients. Instead of digging through 28 days of data by hand, he asks his agent which pages are losing clicks and for three update opportunities, then makes the changes in the same chat. He picked this one because it doesn't have security issues. Some others out there are probably third parties spoofing a Search Console MCP to get your data. It's funny, because look, it has about 150 stars. That's nothing compared to these big popular ones. And I feel like you're calling me out a little bit. I get the emails from Google Search Console telling me there's a problem with a page, or a 404. I forward it to my agent and say fix it. I should go straight to the MCP and let my agent see these tools without me opening it in a browser. I'm adding this one as soon as we're done recording. ## OpenSEO [Watch this part of the episode (22:56)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1376s) Ryan's next pick, [OpenSEO](https://github.com/every-app/open-seo), is basically a clone of Semrush and Ahrefs. The hosted version is about 10 bucks a month, and the whole thing is in a public repo. It uses DataForSEO behind the scenes, so Ryan goes straight to the DataForSEO MCP instead. His point is that the big SEO tools are losing their moat one day at a time. Their data is the only moat they have left. [![The every-app/open-seo repository on GitHub, an open source alternative to Semrush and Ahrefs, with its keyword research screen and topics like Google Search Console MCP, SEO agent, and site audit](/images/blog/best-free-github-repos/open-seo-repo.jpg)](/images/blog/best-free-github-repos/open-seo-repo.jpg) OpenSEO, an open source alternative to Semrush and Ahrefs. Say somebody hits fork on this. A fork is duplicate it, but now it's my own. Then here's what I'd tell people to do: 1. Scan it for security issues and malicious intent, with the prompt from above. 2. If it's clean, tell your agent what you run: I have these websites, I have a blog, I do landing pages to sell a digital product, whatever it is. 3. Ask, what should I add or take away from this to customize it to my use case? If your AI agent already has a bunch of your work in it, like a Claude project, it'll know exactly what to give you or take out. Ryan would have it scan your whole VS Code workspace and your client work, and figure out what's worth including. ## Newsjack, an AI PR team [Watch this part of the episode (25:52)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1552s) [Newsjack](https://github.com/elvisun/newsjack) is a set of open source skills that turns your agent into a PR team. Ryan says PR outreach is the hardest part of SEO. Newsjack finds journalists, takes your existing content, writes the emails, and pitches them, all to get you featured and earn backlinks. I hadn't heard of that one either, so Ryan was teaching me stuff. Ryan added a caveat. If you can't get backlinks, the usual culprit is content nobody cares enough to feature. You have to create interesting stuff first. ## HyperFrames [Watch this part of the episode (27:53)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1673s) I'd used [HyperFrames](https://github.com/heygen-com/hyperframes) three times already the day we recorded, and it was only lunch. I'll give HeyGen credit. They're a video company that did things the traditional way. Then, I want to say February or so this year, they said, we're going to create a whole new way to edit video, through HTML. If you're not a coder, I'm not either, don't be intimidated. HTML is what every website is built on. It's a way to display stuff. Well, guess what's good at writing HTML? Not Aaron. Aaron's coding tool: Claude Code, Codex, Grok Bot, whatever. Now your agent can do visual things with code, and it's easy to edit. Once you render captions into a video, they're burned in. You can't get them out. HTML says here's a box with captions, and behind it, here's a box with Aaron. It's free. You don't pay per use. Your AI agent is all you need to run it. [![The HyperFrames Studio home page: The video editor built for agents, with a download button and the install command npx skills add heygen-com/hyperframes](/images/blog/github-for-marketers/hyperframes-studio.jpg)](/images/blog/github-for-marketers/hyperframes-studio.jpg) HyperFrames Studio, the desktop app with a transcript-based editor. A lot of people said it opens in a localhost browser tab and they still need a visual interface, some kind of timeline. So HeyGen made HyperFrames Studio, a desktop app. I know it's out on Mac. I put our podcast from two days earlier in there with three feeds: Ryan's camera, my camera, and his screen share. It lined them up and gave me a transcript to edit by, running through Claude Code on my computer, and I don't have to pay anybody AI credits to use it. Use a repo to come up with a video editing skill, whether you clip a podcast, make explainers, or record lectures. Have it use HyperFrames, then update the skill every day when you're done: what did we learn? Styles, colors, captions, edits, intros, outros, music. Keep that in a GitHub repo of your own. Tomorrow, say, pull up my video editing repo and cut five clips from this for Instagram Reels. More on that in [AI video editing with Claude](/blog/ai-video-editing-with-claude) and [my Codex and HyperFrames workflow](/blog/codex-hyperframes-video-editing-workflow). ## Postiz: self-hosting isn't free [Watch this part of the episode (30:57)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=1857s) [Postiz](https://github.com/gitroomhq/postiz-app) is a social media scheduler with a full public repo, and Ryan points out that open sourcing it is how Postiz got popular in the first place. You can fork it and make your own scheduler for your AI agents, instead of paying Buffer or Hootsuite. Some of those are 40 or 50 bucks a month. So I asked Ryan, why wouldn't I self-host this myself instead of paying, let's say, 20 bucks a month? The answer is, say you want it to post to your Twitter. Hey Claude, post a tweet for me through my self-hosted version. You'll need a developer account on that platform, and you pay per use. Sometimes it's about a cent. That's instead of 20 bucks a month to get access, where they keep the difference between their API cost to post your stuff and what you pay every month. So it isn't free. You're also responsible for updates and security issues, like if there's a vulnerability in it. I don't vibe code this for multiple reasons, and that's one of them. If I got my social accounts, or the accounts of companies I work with, banned, that'd be a major issue, so paying is worth it. We went category by category on that question in [build it or buy it](/blog/build-or-buy-saas). ## My picks, starting with an AI writing audit [Watch this part of the episode (34:16)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=2056s) I did a mix of big repos with tens of thousands or over a hundred thousand stars, and small ones, like my own. I'm a big fan of having some kind of gate that AI-generated writing has to go through before you post it, publish it, or send it. If you haven't made your own, don't just take mine and use it. Fork mine. [![Aaron Makelky's ai-writing-audit repository on GitHub, which checks written text for common signs of AI-generated writing, suggests fixes, and creates a change log](/images/blog/build-or-buy-saas/ai-writing-audit-repo.jpg)](/images/blog/build-or-buy-saas/ai-writing-audit-repo.jpg) My [AI Writing Audit](https://github.com/a-makelky/ai-writing-audit) repo. Fork it and add your own rules. It's called [AI Writing Audit](https://github.com/a-makelky/ai-writing-audit). It takes common patterns and says, this sounds like Claude. Then it keeps a change log of its edits and cleans the text up for you. I update it every month or two. Add your own if there are things you never want it to use, then put in a hook or a system prompt that says: any time another person is going to read generated text, use this skill before you ship it, send the message, or post it. Ryan has an anti-slop skill, and a rule in his AGENTS.md says every piece of writing has to pass it. Maybe we should merge ours into one super one. We'll have to do that another time. ## Herdr: one terminal for every machine [Watch this part of the episode (35:42)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=2142s) We don't talk about terminals a lot. I used to think terminals were dead, and a desktop app or a VS Code-type IDE was the way to go. [Herdr](https://github.com/herdrdev/herdr) is free and open source, so you can customize it. I have some crazy elements in mine just for fun. It lets you work across different terminal sessions, on different computers, in different environments, all from one UI. I have a Mac Studio, a MacBook, a Linux desktop, and Grok Bot's virtual machine. I can use local coding agents from one terminal on any one of those devices and control jobs on the others. When I do video projects with [Claude Opus](/blog/claude-opus-5-5-best-ai-model), I start them on the Mac Studio. Then I can open Herdr on a MacBook, walk away, be in another country on a VPN, and see all of them instead of switching tabs. If you like running coding agents on your own devices, not in the cloud, try Herdr. ## Cloudflare OS and Whisper [Watch this part of the episode (37:28)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=2248s) If you've ever worked on a team and worried the non-technical people would break stuff or vibe code a bunch of slop, that's one of the main reasons Cloudflare built [Cloudflare OS](https://github.com/cloudflare/cloudflare-os). It connects a team's work together. You can use tokens through their portal to run models, and you can build little one-off tools that are sandboxed, so they don't leak anywhere, break anything, or touch company data a non-technical person wouldn't know how to safeguard. It's like a digital operating system for your company. One I use every day is [Whisper](https://github.com/openai/whisper). Everybody should have a local model. It doesn't have to be a big one, because all we're doing is transcription. If I pull a video file and just want a transcript, I don't want to send it to ChatGPT or Claude in the cloud. I want something small on my device. The biggest ones are like four gigs, I think, so even a little laptop can run them, and nothing leaves your device. ## Matt Pocock's skills and Google's DESIGN.md [Watch this part of the episode (38:46)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=2326s) If you haven't heard of Matt Pocock, he has a repo called just [skills](https://github.com/mattpocock/skills), one of the most starred GitHub repos of all time. It's for people building tools. He's a developer, and he's big on YouTube and Twitter. What I've learned from him is the vocabulary, the terminology, and the approach to building web apps, software, and landing pages. It makes me more technical and helps my AI tool understand what I want. He's a perfect resource for people like us. The last one is from Google, and it has about 28,000 stars. I'm shocked it's that few. A lot of us started making skills for writing and coding. Google came up with a whole new primitive, a type of file called [DESIGN.md](https://github.com/google-labs-code/design.md). Give the repo and a link to a site like ryandoser.com to your agent and say, build me a DESIGN.md. I want to recreate this visually, with fidelity. [![The google-labs-code/design.md repository on GitHub: a format specification for describing a visual identity to coding agents, with an example file listing brand colors, typography, rounded corners, and spacing](/images/blog/best-free-github-repos/design-md-repo.jpg)](/images/blog/best-free-github-repos/design-md-repo.jpg) A DESIGN.md puts colors, fonts, and spacing in a file your agent can read. It can be web design, app design, video design, anything you look at and see colors, shapes, and animations. It puts that in a language your agent can understand and use. Connect it to HeyGen's HyperFrames: have a DESIGN.md for the style of your videos or your podcast, have Claude or Codex edit your video, and you'll get way better, more consistent results. ## Where to start [Watch this part of the episode (40:42)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=2442s) After our last GitHub episode, a few people commented that we didn't show them how to do anything. Ryan says to plug the transcript into AI and ask what to do. Then create a free GitHub account and connect it to your AI system of choice. In Claude and ChatGPT that's one click. In Claude Code or Codex there's an authentication step, and if it's confusing, take screenshots and ask AI to walk you through it. It's a backpack for your AI agent that you can take to any other AI agent or project. That's how I think of it. More on that in [Your AI app should not own your work](/blog/your-ai-app-should-not-own-your-work). ## Curiosity is the superpower [Watch this part of the episode (42:00)](https://www.youtube.com/watch?v=HNyKJwpsbpU&t=2520s) It's like Brussels sprouts. People tell me they don't like them, and I go, how many times have you had them? Well, I haven't, but I know I don't like them. People rant about AI who have never used it for more than a chat box, saying what AI can't do. Don't listen to those people. I block them in my feed. I'm not wasting my brain cells on them. Not everyone likes me or my thoughts, and I'm not offended. Those are people criticizing a system they don't understand. Take AI thumbnails. I'm not a thumbnail designer, but I know click rate. Click-through rate on YouTube is everything, and all the video editing I'm decent at means nothing if the packaging sucks. I'm not big enough on YouTube to justify 500 bucks for a good thumbnail from a human designer. I've seen what companies pay agencies for that. GPT Image 2.5 is way better than I can do, so let's just use that. The real superpower in 2026, and even more going forward, is curiosity. Even just ask Claude Code, can you do this? Ninety-nine percent of people will never do that. If you even try, you're ahead. That's what this show is about. You see stuff from us every week and go, I've got to check that out. I've got to add that. I've got to fork it. I've got to use it.

Ryan Doser says to have it scan the entire repository first and look for anything malicious: prompt injections, files that could take your API keys, or anything that could steal your data. Aaron Makelky has seen repos with hidden instructions that older models would follow, like syncing all your data to someone else. Run the scan before you fork it, clone it, or plug it in. ### What's the difference between starring and forking a GitHub repo? Aaron describes a star as a bookmark that doesn't have to live in your browser or in Notion. You can always find your starred repos, and you can tell your AI tool to look at them. A fork duplicates the repo so it's your own copy. He forks skill repos, scans them, then asks his agent what to add or take away for his own use case. ### Is self-hosting an open source tool like Postiz free? Not really. Aaron points out that posting to a platform like X from a self-hosted scheduler needs a developer account on that platform, and you pay per use, sometimes about a cent a post. You're also responsible for updates and security issues. He pays for his scheduler because getting his social accounts banned would be a major issue. ### Which free GitHub repos does Aaron use himself? His own AI Writing Audit, which checks generated text for common AI writing patterns before anyone reads it; Herdr, for running coding agents across several computers from one terminal; Whisper, for private transcription on his own device; and HyperFrames, which he uses for video editing every day. He also recommended Cloudflare OS, Matt Pocock's skills, and Google's DESIGN.md. ### What does Aaron mean by GitHub being a backpack for your AI agent? Your skills, instructions, and files live in a GitHub repo instead of inside one AI app, so you can take them to any other AI agent or project. He calls GitHub his gateway into AI coding and building, more than ChatGPT or Claude, and says the single best thing to do is make a free account.
