Open-source, resource-efficient coding agent harness built for multi-session workflows, deep customizability, and high performance.
jcode is an open-source (MIT) next-generation coding agent harness designed to raise the skill ceiling for developers running many parallel agent sessions on their machine. It runs on Linux, macOS, and Windows and is optimized to be lean: benchmarks on the project's own README show baseline RAM under 30 MB for a single idle session with local embeddings off, several times leaner than comparable tools like pi. Beyond footprint, jcode is built around three ideas — multi-session workflows so a developer can juggle several agents at once, infinite customizability so the harness can be shaped to any language/toolchain, and raw performance so every metric is optimized to the bone. Distribution is via GitHub Releases with Homebrew and source-build paths documented, plus an active Discord community and dedicated docs and benchmark pages at jcode.sh.
