Open-source Rust agent engine and terminal client with provider choice, approvals and receipts
jcodeは、1jehuangが公開しているオープンソースの開発ツールプロジェクトです(GitHub: 1jehuang/jcode)。GitHubスターは20,354、フォークは2,367で、MITライセンスの下で公開されています。GitHubでの最終更新は2026年10月8日です。
A high-performance coding agent harness in Rust - fast TUI, swarms and every provider
Decide whether to use a subscription login (Claude etc.), an API provider, or a local server like Ollama or LM Studio.
Install it with the official installer for macOS/Linux or Windows.
Run jcode login, pick your provider or add an OpenAI-compatible endpoint or MCP servers in the config.
Open a project, choose a model, and give the agent its first coding task.
The README benchmarks fast startup (time to first frame/input) and low RAM, including headless swarm workers.
Keeps memory across sessions so the agent retains project context.
Run headless worker agents in parallel with configurable effort levels for bigger tasks.
Side panels, diagrams and info widgets render inside the TUI with smooth scrolling.
Built-in profiles for OpenRouter, DeepSeek, Kimi, Hugging Face and many other OpenAI-compatible endpoints, plus arbitrary custom endpoints.
Profiles for local runtimes such as Ollama and LM Studio, and self-hosted vLLM endpoints.
Get the source code from GitHub and enter the project directory.
git clone https://github.com/1jehuang/jcode.git
cd jcodeUse the installer for macOS and Linux (a PowerShell installer is provided for Windows 11).
# Run the install command from the README's Installation sectionAuthenticate with your provider, then start the agent in your project.
jcode login
jcodeIt is maintained by 1jehuang and contributors on GitHub.
Yes - jcode is MIT licensed and free. Models you connect may be paid subscriptions or APIs.
jcode itself charges nothing, but you need model access: a supported subscription login, your own API keys, or a free local model server.
Compared with Claude Code, jcode is provider-agnostic and Rust-built for speed and low memory, with swarm workers; compared with IDE agents, it is terminal-first.
Install with the README's installer, run jcode login, choose a model, and start a session in your project.
