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.
A spec-driven AI IDE and agent platform that plans, builds, reviews, and verifies real engineering work.
You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.
Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your review.
Long tasks split into checked steps so agents cannot shortcut a failed test, and review agents inspect diffs before a human approves a merge.
Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.
