Freebuff2api Openai Proxy

This is a Go-based proxy server that sits between any OpenAI-compatible client and Freebuff's free models, translating requests on the fly so you can use the standard OpenAI SDK without modifications. It handles token rotation across multiple Freebuff accounts, randomizes client fingerprints to mimic the official SDK, and ships as a multi-arch Docker image. The setup is straightforward: grab auth tokens from the Freebuff CLI or web interface, spin up the container with environment variables, and point your existing code at localhost:8080. Useful if you want to experiment with Freebuff models in production tooling or bypass rate limits with token pooling, though you'll need to manage multiple accounts yourself.

Freebuff2API OpenAI Proxy

Skill by ara.so — Daily 2026 Skills collection.

Freebuff2API is an OpenAI-compatible proxy server written in Go that translates standard OpenAI API requests into Freebuff's backend format. It enables any OpenAI-compatible client, SDK, or CLI tool to use Freebuff's free models without modification.

What It Does

  • Exposes standard OpenAI endpoints (/v1/chat/completions, etc.)
  • Dynamically randomizes client fingerprints to mimic official Freebuff SDK behavior
  • Rotates multiple auth tokens on a configurable interval
  • Routes outbound traffic through an optional HTTP proxy
  • Ships as a multi-arch Docker image for easy deployment

Getting Auth Tokens

Before deploying, obtain one or more Freebuff auth tokens:

Method 1 — Web (easiest): Visit https://freebuff.llm.pm, log in with your Freebuff account, and copy the displayed token.

Method 2 — Freebuff CLI:

npm i -g freebuff
freebuff  # follow login prompts

Token is stored at:

  • Linux/macOS: ~/.config/manicode/credentials.json
  • Windows: C:\Users\<username>\.config\manicode\credentials.json
