FreeDeepseekAPI is a local proxy server that connects to your DeepSeek web chat account and exposes it as a standard API that AI tools can talk to. If you use AI coding assistants, chat clients, or development tools that expect to connect to an OpenAI-compatible or Anthropic-compatible API endpoint, this project lets you route those requests through the free DeepSeek web interface rather than paying for API credits. The way it works is straightforward: you log into your normal DeepSeek account through a separate Chrome browser profile, which saves your session. The proxy server then runs locally on your machine and translates incoming API requests into the DeepSeek web chat format, sends them through that saved browser session, and returns the responses in whatever format the client expects. It supports the OpenAI chat completions format, the Anthropic messages format, and the OpenAI Responses format, so a wide range of tools can connect to it without modification. Features include streaming responses (where text arrives word by word rather than all at once), tool calling (where the AI can indicate it wants to run a function in your code), and DeepSeek's reasoning mode, which exposes the model's chain-of-thought alongside the final answer. It also supports web search variants of the models, session isolation for running multiple agents at once, and automatic recovery when a browser session expires. Setup involves cloning the repository, running an authentication step that walks you through logging into DeepSeek in a separate Chrome window, then starting the server. It requires Node.js 18 or newer and has no npm package dependencies. The server listens on localhost port 9655 by default. The README notes this is an experimental project that reverse-proxies the web interface, which DeepSeek can change at any time without notice. For anything in production or requiring reliability guarantees, the official paid DeepSeek API is the recommended option. The README is written primarily in Russian. The full README is longer than what was shown.
