jcode

Open-source Rust coding agents for your terminal, built for parallelism

Rust harness with low per-session overhead

Each additional jcode session costs megabytes rather than hundreds of megabytes, and a new session is ready for input in well under a tenth of a second, so you can run many agents on hardware you already own.

Agent swarms and background tasks

Launch multiple agents in parallel, hand off long jobs to background or headless execution, and keep durable task state so work survives interruption.

Benchmark-driven optimization

The jcode bench suite (float-print, json-unescape, utf16-transcode) scores optimization depth on an analog axis with no capping timeouts, so capability differences stay visible.

Confidence-checked completion

Agents rate confidence when a task item is assigned and again when it is finished; a sudden jump triggers forced re-verification instead of blind acceptance.

Strengths & Pros

+Open-source agent with a one-command install for macOS, Linux and Windows
+Memory footprint per extra session is dramatically lower than typical terminal agents
+Runs many parallel agents and durable background tasks from one terminal
