Coding Agent Harness

About jcode

The next generation coding agent harness to raise the skill ceiling. Built for multi-session workflows, infinite customizability, and performance.

Need Windows, Homebrew, source builds, provider setup, or tell your agent to set it up for you? Jump to detailed installation.

jcode is built to be as performant and resource efficient as possible. Every metric is optimized to the bone, which is important for scaling multi-session workflows. Here we sample a few metrics to show the difference: RAM usage and boot up.
