jcode vs oh-my-pi

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.; oh-my-pi: oh-my-pi (omp) is a terminal coding agent forked from Mario Zechner's Pi, with LSP operations wired into every write, a real debugger over DAP, persistent Python and Bun kernels, and first-class subagents. It supports 60+ providers, and much of its tooling runs in-process from a Rust core.
