What is Fuxi?
FuXi is a fast, self-contained AI coding agent that lives in your terminal — edit code, run commands, and drive tools, with cost-aware routing across LLM providers.
Overview of Fuxi
What it is
FuXi is a fast, self-contained terminal AI coding agent. It reads code, edits files, runs commands, and drives tools from a rich TUI. It features cost-aware routing across LLM providers and automatic failover. Built in Go, it ships as one static binary with no runtime dependencies. It is terminal-first, provider-agnostic, and requires the user to bring their own API key. It also acts as an MCP client and is self-updating. The product source is proprietary; this repository hosts documentation, installers, and the issue tracker.
Key features
- Terminal-first TUI for editing code, running commands, and driving tools - Cost-aware routing across LLM providers with automatic failover - Bring your own API key; supports environment variables and config file - MCP client integration - Self-updating binary - Permission modes: default, plan, and bypassPermissions (with safety blocks on dangerous commands)
- Sessions, checkpoints, memory, and audit logs stored locally
Use cases
- Editing and debugging code directly from the terminal - Running commands and managing development workflows - Using multiple LLM providers with cost optimization - Automating tasks in a container or VM with bypassPermissions mode - Headless/CI usage via token setup
