Jcode

Jcode is an open-source AI coding agent built for the terminal and written in Rust, bringing a fast and lightweight experience right to where developers already work. Instead of jumping between tools, you can hand it real software tasks and let it handle the heavy lifting directly from your command line.

What sets Jcode apart is how it stays useful over the long run. It comes with durable memory that persists across sessions, semantic memory retrieval to surface the right context at the right time, background tasks for work that runs while you do something else, and agent swarms that can tackle multiple efforts in parallel. Automatic task continuation picks up where things left off, confidence checking keeps results trustworthy, and benchmark-driven optimization helps the agent improve how it works on your codebase.

Getting started is flexible and free: bring your own personal API keys, sign in with a supported OAuth subscription, or run local models through Ollama and LM Studio if you prefer everything to stay on your machine. Teams that need more can subscribe to hosted model inference for managed convenience, or contact the company for enterprise deployment with dedicated billing, security, and support.
