Download Jcode Desktop for macOS, Linux, or Windows. A fast, native spatial workspace for running many Jcode coding sessions at once. jcode is an open-source AI coding agent for your terminal, written in Rust. Run agent swarms and background tasks with low memory use. Install with one command. Jcode is inventing a new form of customizability. One that doesn't limit you to what a plugin or extension can do. Tell your jcode agent to enter self dev mode, and it will start modifying its own source code. Jcode is optimized to iterate on itself. 为什么同时用三个，因为各有各的长处，也有着一些不能满足需求的地方。 所以今天看到这个开源项目： jcode ，纯 Rust 编写，9.2 万行代码，空闲内存只有 28MB（Trae 启动时，经常内存告警），很是吸引我。 吸引我的是： Swarm 多智能体协作 和持久化语义记忆系统。 jcode 是 Rust 实现的下一代 Coding Agent Harness，支持语义记忆图、多智能体 Swarm 协作、内置浏览器自动化和 20+ 模型 Provider OAuth 登录，相比 Claude Code 在 RAM 占用和启动速度上有显著优势。 性能与资源效率 jcode 旨在尽可能实现高性能与低资源占用。 每一项指标都被压榨到极致，这对扩展多会话工作流至关重要。 下面我们通过内存占用与启动速度的几项数据，来直观展示差距。 Jcode is an open-source terminal coding agent written in Rust. It connects AI models to your local project so the agent can work with files, run commands, use tools, and continue coding tasks from the terminal. jcode is an open-source AI coding agent for your terminal, desktop and browser. Describe tasks in plain language — jcode reads your codebase, writes surgical edits, runs commands, and reports every step. jcode 的定位：用 Rust 重写整个 Harness，把性能拉到天花板，让多 Agent 协作真正实用。 口号是“next generation coding agent harness”。 Harness 才是 AI 编码工具的真正战场。 模型天天卷参数，Harness 却决定“模型能不能靠谱落地”。 Describe a task in plain language. [J]CODE reads your codebase, writes surgical edits, runs commands, and shows every step — no black boxes. Use it in your terminal, a browser, or a native desktop app. Work locally or on a remote box over SSH or Docker. Bring any OpenAI-compatible model.
