A multi-session coding agent harness with fast local TUI, memory features, and MCP support; verified 6065★, pushed 2026-05-14.

Best for: Builders running multi-session coding agents who care about performance and control

Works with: macOS/Linux/Windows; integrates with MCP-capable clients per README

Setup time: 8-15 minutes

Key facts (verified)

  • GitHub: 6065 stars · 646 forks · pushed 2026-05-14.
  • License: MIT · owner avatar + repo URL verified via GitHub API.
  • README-backed entrypoint: jcode.

Main

  • Use jcode as a harness (not just a chat): keep separate sessions per task/branch to reduce context mixing and rework.

  • Start with the README install script, then lock in your provider setup before running longer sessions.

  • Treat performance as a feature: the README includes concrete RAM comparisons for multi-session workflows.

  • When you need tools, prefer MCP-backed integrations so the agent can call structured actions instead of free-form shell guesses.

Performance & Resource Efficiency

jcode is built to be as performant and resource efficient as possible. Every metric is optimized to the bone, which is important for scaling multi-session workflows. Here we sample a few metrics to show the difference: RAM usage and boot up.

RAM comparison

1 active session

Source-backed notes

  • README includes an install script entrypoint scripts/install.sh and a Homebrew formula (brew install jcode).
  • README lists a performance section with RAM comparisons for 1 vs 10 active sessions.
  • GitHub topics include coding-agent, mcp, and tui (verified via GitHub API).

FAQ

  • Is jcode free to use?: Yes—it's MIT licensed per GitHub license metadata.
  • How do I install it on macOS?: README shows Homebrew (brew install jcode) and a curl install script.
  • Does it support MCP?: Yes—GitHub topics and README positioning mention MCP support; verify client configuration in the repo docs.
