jcode is a coding agent harness built for maximum RAM efficiency and performance, targeting multi-session workflows where resource usage matters. Its README benchmarks show it using 27.8 MB PSS with local embedding off for a single active session, compared to 140–387 MB for tools like Codex CLI, OpenCode, and Claude Code. It runs on Linux, macOS, and Windows, and is aimed at developers who need to scale many concurrent agent sessions without exhausting memory.
