jcode

jcode is an open-source AI coding agent for the terminal that provides durable memory, background tasks, and agent swarms.

Jcode is an open-source AI coding agent written in Rust designed for the terminal. It is built for developers who want to run dozens of coding agents in parallel without ballooning RAM consumption. The tool features durable memory, background tasks, agent swarms, a todo confidence tracing system, and automated pokes to keep agents working. It supports your own API keys, supported OAuth subscriptions, local models through Ollama or LM Studio, and Jcode Cloud. Jcode is MIT licensed and lets you inspect and modify the source code.
