FuXi

FuXi is a self-contained terminal AI coding agent developed by FUXI. Built in Go and distributed as a static binary, it uses a Think → Act → Verify loop to read and edit code, run shell commands, drive tools, connect to MCP servers, and route requests across multiple LLM providers with automatic failover and cost-aware settings.

Its built-in capabilities include file operations, shell execution, code search, web fetching, LSP diagnostics, Jupyter, browser use, background tasks, and parallel sub-agents. Shell commands pass an AST-based safety classifier, while permissions and audit logs govern autonomous actions. Sessions persist to disk, with checkpoints for resuming, rolling back, or forking; the TUI also supports memory consolidation and automatic context compaction.

FuXi supports provider API keys or FuXi OAuth, configurable OpenAI-compatible endpoints, MCP clients, hooks, skills, plugins, and slash commands. The repository contains documentation, installers, release information, and issue-tracking materials; it states that the product source is proprietary and not published.
