Open-source coding harness jcode runs on 27MB RAM, claims to crush Cursor and Claude Code
abhishek__AI · x · 2026-08-18
The open-source project jcode (17.9k GitHub stars) focuses on extreme resource efficiency: just 27MB of RAM, 14ms time-to-first-frame, with multi-agent workflows, autonomous agent swarms, and a human-like memory system.
The author claims it outperforms Cursor, Claude Code, Codex CLI, and Copilot CLI by a wide margin. Fully open source with one-line install scripts for macOS, Linux, and Windows — well suited for developers running many concurrent agent sessions.
