About

jcode is a terminal coding agent written in Rust and designed for running many agent sessions at once. Its README benchmarks show about 71 MB for the first session and about 3 MB for each additional one, and a 19 ms time to first input, compared with other coding agents. In its swarm mode, agents in the same repository are managed by a server that notifies one agent when another edits a file it has read. It installs with a shell script on macOS and Linux.

Use cases: coding, agent-orchestration, code-generation
