jcode vs Kun

jcode: jcode is a coding agent harness written in Rust, built to run dozens of agents in parallel with little RAM and near-instant startup. Agents in the same repo are coordinated by a server that notifies them of conflicting edits and lets them message each other or spawn their own swarms.; Kun: Kun is a local-first desktop AI workspace where code, documents and agent chats share one local runtime, with sessions, memory and settings kept on your machine. It has Code and Work modes, a design canvas, chats and group rooms with Codex, Claude Code and OpenCode, and a terminal TUI on the same kun serve runtime.
