Alpha Code: the free AI coding agent for your terminal.
AlphaCode (also searched as alpha code, alpha codes or alpha coder) is an open-source AI coding console written in Rust. Describe what you want in plain English; it reads your project, edits files and runs your tests. No API key, no signup.
Why developers pick Alpha Code
Free from the first command
A built-in AI provider is pre-configured. Add Claude, GPT, Gemini or local Ollama later.
Does the work, not just chat
Plans, edits files, runs tests and self-reviews before it says it is done.
Fast and lean
A single Rust binary for Windows, macOS and Linux. Works over SSH and tmux.
You stay in control
Review every diff and approve risky actions. Sessions resume after a crash.
