Hello, fellow NodeLoc members, today I’d like to share a treasure of a project I just discovered—it’s a godsend for developers and AI enthusiasts!
Why recommend it?
Have you ever run into these pain points:
- Want to use GPT-4o or Llama 3, but the official API is too expensive?
- Want to test different models, but registering accounts one by one is too much hassle?
- Don’t want to deal with complicated authentication (Auth) and API key configuration while coding?
This project solves all of the above perfectly! It is a Node.js-based API gateway that integrates 25+ free AI chat endpoints, including familiar ones like OpenRouter, Pollinations, PublicAI, etc.
Key highlights:
- Completely free & unlimited: No API key required, no authentication required, and theoretically no call limit (as long as the upstream doesn’t go down).
- Ready to use out of the box: The author has already deployed a Vercel demo site; you can call it directly or deploy it to your own Vercel with one click.
- Rich model selection: Covers GPT-3.5 Turbo, GPT-4o-mini, Llama Instant, and various role-playing models (such as Dopple, Chat with Fiction).
- Extremely simple: Just send a POST request with
userMessageand you’ll get a reply.
Tech stack:
Node.js + Express.js + Axios. The code structure is clear and very suitable for learning or secondary development.
Use cases:
- Personal projects/bot development practice
- Need a backup API in case the main endpoint goes down
- Learn how to aggregate third-party AI APIs
Finally:
The project is open source (GPL-3.0). If you find it useful, remember to go to GitHub and give the author a Star 
to show your support!
