FuXi is a fast, self-contained **terminal AI coding agent**. It reads code, edits
files, runs commands, and drives tools from a rich TUI, with cost-aware routing
across LLM providers and automatic failover. Built in Go, it ships as one static
binary with no runtime dependencies.
**Terminal-first** · **Provider-agnostic** · **Bring your own key** · **MCP client** · **Self-updating**
Homepage: **https://www.fuxicode.com**
FuXi's roughly **2 million lines of code** were written entirely by FuXi itself.
## Install
**macOS / Linux**
```bash
curl -fsSL https://downloads.fuxicode.com/bootstrap.sh | bash
```
**Windows (PowerShell)**
```powershell
irm https://downloads.fuxicode.com/bootstrap.ps1 | iex
```
**Windows (CMD)**
```bat
curl -fsSL https://downloads.fuxicode.com/install.cmd -o "%TEMP%\fuxi-install.cmd" && "%TEMP%\fuxi-install.cmd"
```
Then verify and launch:
```bash
fuxi --version
fuxi doctor # environment sanity checks
fuxi # start a session
```
Install and upgrade are the same command. Full options, uninstall steps, and
troubleshooting: [setup docs](docs/usage.md#installation).
## Get started
A FuXi account is required. Run `fuxi`, then:
1. **Register and sign in** — `fuxi login` (or `fuxi setup-token` for
headless/CI). Registration processes only minimal account data.
2. **Connect a model (optional)** — sign-in gives access to FuXi-managed models;
to use your own provider instead, set an API key via environment variable or
`~/.fuxi/config.yaml` (`fuxi init` generates a template). Or run `fuxi wizard`.
Then type a prompt and press Enter, for example:
```text
Fix the failing tests in this repository.
```
Useful commands: `/model` switch models · `/help` browse all commands ·
`/config` open settings · `/privacy-settings` privacy controls · `/exit` quit.
Full walkthrough: [usage guide](docs/usage.md).
## Permissions
Sensitive tool calls ask for approval unless you change the permission mode
at launch.
`--dangerously-skip-permissions` starts in `bypassPermissions`, so tool calls
run without a prompt. Extreme commands such as `rm -rf /` are still blocked.
Use it only in a container or VM; on Linux and macOS, root and `sudo` are
rejected.
`--allow-dangerously-skip-permissions` keeps the normal mode and adds
`bypassPermissions` to the `Shift+Tab` cycle.
`--permission-mode bypassPermissions` behaves like
`--dangerously-skip-permissions`. The same flag also accepts `default` and
`plan`.
## Data, privacy, and retention
FuXi runs on your machine and keeps your work local.
- **By default, your code and conversations are never collected, stored, or
retained by FuXi.** With your own key they go straight to the provider you
choose; with FuXi-managed models they are transmitted only to serve that
request. Conversation content is sent to FuXi only if you explicitly enable
`send_conversations` (off by default).
- **Credentials stay in local `~/.fuxi/`** and are never uploaded.
- **Sessions, checkpoints, memory, and audit logs** live on your device and can
be deleted at any time by removing the config directory.
- FuXi processes limited account and technical information to operate the
service; the available analytics are disclosed and can be turned off. See
[Privacy Controls](security-privacy/DATA_PROTECTION.md).
