About Jcode
Jcode is an open source AI coding agent for the terminal, written in Rust and installed with a single command. It is designed to run many agent sessions at once on one machine, with swarm style coordination, background tasks and a small memory footprint.
The terminal interface renders images and LaTeX inline, shows structured edit blocks and running batch tools, and notifies the user when agents in a swarm conflict over a file. A desktop beta is available alongside builds for macOS, Linux and Windows. The vendor publishes its own measurements of added memory per session, reporting about 10.4 MB for an interactive jcode session against 212.7 MB for Claude Code in its test, and also compares startup times against several other coding agents.
Developers who want to run parallel coding agents on a laptop, or who prefer to bring their own model access, are the intended users. The software can use personal API keys, supported OAuth subscriptions, or local models through Ollama or LM Studio.
The software itself is free under the MIT license with no feature gates. Optional hosted inference is sold as a monthly subscription from $10, with plan choices of $10, $20, $50, $100, $200, $300, $500 and $1,000. Each payment grants inference credit worth double the plan price, plus 50 Jcode Cloud machine hours per $10, and usage beyond the credit is billed at provider API prices up to an automatic limit of ten times the plan. Enterprise pricing is custom.
