Open-source Rust coding agents for your terminal, built for parallelism
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.
Launch multiple agents in parallel, hand off long jobs to background or headless execution, and keep durable task state so work survives interruption.
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.
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.
Run many coding agents in parallel, each in its own worktree
Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.
Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.
A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.
Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.
