Yesterday someone got tired of paying for 10 AI subscriptions and built a public list instead.
u/Axintwo dropped a GitHub repo with 550+ free or cheap tools specifically for vibe coding. Local models, free LLM APIs, coding IDEs, RAG stacks, agent frameworks, speech and video APIs. The whole stack. Curated. Usable. Free or nearly free. If you have been quietly watching your monthly AI bill creep toward the cost of a second rent payment, this one is for you.
The timing matters too. Vibe coding has moved from a niche developer thing to something founders, solo builders, and product people are actually using to ship real software. The tools ecosystem has exploded alongside it. But finding what is free, what is actually good, and what plays well together is still painful. You end up with 47 open tabs, three Notion docs of bookmarks, and no working prototype. This repo is a shortcut through all of that noise.
The twist
Most tool lists are just lists. This one includes ready-to-use stack combos. Pre-assembled setups you can copy and actually start building with today. That’s what separates it from every other bookmark you’ll forget about.
Here’s why that matters. When you’re staring at 550 tools, the problem is not information. It’s decision fatigue. Every tool sounds useful. Every API promises to be the flexible one. You end up spending Saturday researching instead of building. Stack combos flip that dynamic. Someone already made the tradeoffs. They figured out which pieces fit together without weird dependency conflicts, which free tiers are actually generous enough to build on, and which combos cover the most common use cases. You walk in, pick a combo that fits your project, and start writing code. That’s a completely different starting position than a raw list.
The fact that it’s open source and taking pull requests means the combos will keep getting tested and refined by people who actually build with them. This is not a one-time export from someone’s Notion. It’s a living document.
How to actually use it
- 🔍 Go to the stack combos section first. Skip the 500-item scroll if you want to ship something this week. The combos are organized by use case, so you can find what maps to your project without reading every entry. Spend five minutes here instead of two hours in the full list.
- ⚡ Free LLM APIs: Groq for raw speed, OpenRouter for model flexibility, Gemini API for the most generous free tier right now. Groq’s inference is genuinely fast, which matters when you’re prototyping and want tight feedback loops. OpenRouter lets you swap models without rewriting your API calls, which is useful if you don’t know yet which model fits your task best. Gemini’s free tier is surprisingly deep right now. Flash handles most classification and lightweight generation tasks without ever hitting a billing screen.
- 🛠 Local models: Ollama plus Qwen or Llama is your zero-cost baseline. No API keys, no rate limits, no surprises on your bill. Ollama’s setup is genuinely painless these days. Pull a model, run it, point your app at localhost. Qwen2.5 in the 7B range punches well above its size for coding tasks. If you have a machine with a halfway decent GPU you already have a private, unlimited, free LLM sitting there.
- 🤖 Agents and automation: the list covers lightweight agent frameworks beyond LangChain, which is worth the detour if you’re building anything autonomous. LangChain is powerful but it carries a lot of weight for simpler use cases. Some of the lighter frameworks in the repo wire up tool use and multi-step reasoning with a fraction of the boilerplate. If your project does not need the full LangChain surface area, you will probably ship faster with something smaller.
Pro tip
Don’t try to evaluate 550 tools. Pick one category you actually need this week. Go three items deep. Pick one. Build something real. The graveyard of bookmarked tool lists is bigger than any AI model’s context window.
The way to actually benefit from a resource like this is to treat it like a menu, not a textbook. You don’t read a menu cover to cover. You figure out what you’re hungry for, scan that section, pick something, and order. Come back for the next category next time you’re stuck. Builders who ship consistently are not the ones who know the most tools. They’re the ones who know a few tools well enough to move fast. One category, one tool, one working thing. Repeat.
