Overview

jcode is an open-source terminal coding agent written in Rust. When a developer gives instructions in natural language, it helps read and modify project files and perform commands, tests, builds, and Git operations. It runs on macOS, Linux, Windows, and remote servers, and can connect to Claude, OpenAI, Gemini, GitHub Copilot, Ollama, LM Studio, and various OpenAI-compatible models. It provides a swarm feature to run multiple agents simultaneously, semantic-based memory to search and recall conversation history, MCP tool integration, background tasks and automatic retries, auto-poke to continue long-running tasks, session resumption, and remote connections. It displays structured editing, diffs, Mermaid diagrams, images, and progress in the TUI, and also supports SDKs and API bridges. It is suitable for individual developers, open-source contributors, researchers, and development teams looking to automate repetitive code modifications and testing.
