An open-source coding agent
for your terminal, desktop,
browser and editor.
终端、桌面、浏览器、编辑器里都能用的 AI 编程助手。
It reads your project, edits files and runs commands and tests. Have it ask before each step, or work on its own within limits you set. Files its edit tools changed can be rewound. New here? Start with the Studio desktop app. 它会读你的项目、改文件、跑命令和测试。每一步先问你，或在你划定的范围内自己做，由你选；它用编辑工具改过的文件可以退回去。第一次用，从桌面应用 Studio 开始。
You set the permissions. File edits can be rewound.权限你来定，改过的文件能退回。
Read and edit files, run commands and tests, with you in control of each step.读文件、改文件、跑命令和测试，每一步由你掌控。
Permission levels权限分档
Ask before every write and command, or let everyday actions run on their own. Your forbid rules always hold. On macOS and Linux, commands also run in a sandbox that limits where they can write.每次写文件、跑命令都先问你，或让日常操作自动放行。你设的禁止规则始终有效。macOS 和 Linux 上，命令还跑在沙箱里，可写的位置受限。
$ allow edit internal/net/client.go? [y/n/always]
Rewind file edits文件改动可回退
A snapshot is saved before each file change, outside git. Rewind by conversation turn without touching your commit history. Only files changed by its edit tools are covered, not what a shell command did.改文件前先存快照（不走 git），按对话轮次回退，不动提交历史。只覆盖编辑工具改的文件，命令行命令造成的改动不在内。
Plan mode计划模式
It drafts a plan and waits. Work starts only after you approve.先出计划并等你。批准之后才开始动手。
More tools接入更多工具
Connect outside tools through MCP, a common plug-in standard. Write your own skills as Markdown files, and hand side tasks such as research or review to helper agents.用 MCP（通用的工具接入标准）接外部工具，用 Markdown 文件写自己的技能，调研、审查这类支线任务交给辅助智能体。

Nothing else to install不用另外装环境
The command-line tool is a single self-contained program for macOS, Linux and Windows, on Intel/AMD and ARM chips.命令行版就是一个独立的程序，macOS、Linux、Windows 都有，Intel/AMD 和 ARM 芯片都行。

Bring your own model key; DeepSeek is built in, and other OpenAI-compatible services work too. The program runs on your computer. MIT licensed, developed in public.自带模型密钥：内置 DeepSeek，其他兼容 OpenAI 接口的服务也能用。程序跑在你的电脑上。MIT 许可，公开开发。
Four ways to use it. Same program.四种用法，同一套程序。
