A terminal-native AI coding assistant that lives where you work. Multi-provider, fully autonomous, with a built-in browser agent — all at the speed of Rust.
Any fool can write code that a computer can understand. Good programmers write code that humans can understand.— Martin Fowler
YouCoder is not another web wrapper. It's a pure Rust terminal application engineered for speed, privacy, and deep system integration.
Built with Ratatui TUI framework. Zero web bloat — just you, your terminal, and AI.
Rust-powered engine with async I/O. Sub-millisecond UI updates. Streaming responses with zero latency.
Anthropic, OpenAI, DeepSeek, Gemini, Zhipu, MiniMax, Xiaomi — switch with a single config line.
Read, write, edit, grep, glob, web search, browser agent — all built in.
Define specialized AI agents via TOML. Each with its own system prompt, tools, and model.
SQLite persistence for sessions & memories. Context Assembler with domain gating. Auto profile synthesis.
Embedding third channel. Ollama/OpenAI embedding models for semantic code search. Offline indexing + real-time query.
Git workspace snapshots. One-click create/restore/delete/list. SHA256 integrity verification for safe code exploration.
Model Context Protocol support. Connect external tools and data sources — databases, filesystems, web APIs.
The function of good software is to make the complex appear to be simple.— Grady Booch
11 crates, pure state machine, channel-based communication.
Programs must be written for people to read, and only incidentally for machines to execute.— Harold Abelson
一套全面的工具集，赋予 AI 读取、写入、搜索、浏览、分析和执行的能力——全部原生内置，自动修复。
内置三大技能 + 自定义 TOML 技能系统，让 AI 按需调用专业化子智能体。
在隔离子智能体中广域只读探索代码库——找出所有相关代码位置。
网页搜索 + 代码阅读结合，在隔离子智能体中研究技术问题。
审查当前分支变更——标记正确性、安全性、缺失的测试。
The measure of progress in programming is the density of requirements that the code can absorb.— Fred Brooks
YouCoder 覆盖你常用的开发环境——命令行、编辑器、浏览器。同一套 AI 引擎，无处不在。
在终端的每一个像素上释放 AI 的力量。基于 Ratatui TUI 框架，Actor 模型 + mpsc 通道通信，42 FPS 流畅渲染。
在 VS Code 中无缝使用 YouCoder。Inline 代码补全、对话面板、文件编辑——无需离开编辑器，即刻智享编码。
通过浏览器远程连接 YouCoder 引擎。适合在 iPad、Chromebook 或任何无法安装 CLI 的环境中编码协作。
Four distinct modes let you decide how much autonomy the AI has.
Read-only access. Output documentation and designs.
Read freely, write with approval.
Full tool access with per-call approval.
Complete autonomy, no approval prompts.
Bring your own API key. Switch providers with a single config line.
