## What it is
FuXi is a terminal-based AI coding agent built in Go that reads code, edits files, runs commands, and drives tools through a rich TUI using a Think → Act → Verify agentic loop. It ships as a single static binary with cost-aware routing across OpenAI-compatible LLM providers, automatic failover, and MCP client support.

## Use cases
- ai coding agent in the terminal
- edit code and run commands with an llm agent
- use any openai-compatible model for agentic coding
- reduce llm costs with provider routing and failover
- autonomous codebase refactoring with safety guardrails
- claude code alternative for the terminal
- connect mcp tools to a coding assistant

## When to choose
- you want a provider-agnostic terminal coding agent with a single static binary
- you need cost-aware multi-provider LLM routing with failover
- you want built-in shell, file editing, search, and sub-agent tools without plugins
- you prefer bring-your-own-key with fine-grained permissions and audit logging

## When to avoid
- you need an open-source license - FuXi is proprietary despite being on GitHub
- you prefer a GUI or IDE-integrated assistant over a terminal TUI
- you need a fully self-hosted model pipeline rather than API-based providers
- you require auditable open-source code for security-sensitive environments
