JCode vs OpenChamber
OpenChamber is a macOS desktop app for OpenCode. Also available as a PWA. Open source under MIT.
JCode is an app for orchestrating coding agents, with native clients on desktop, mobile, web, and the CLI. Open source (AGPL-3.0).
Why pick JCode
OpenChamber runs on macOS, around OpenCode, with a phone PWA. JCode runs OpenCode too, on macOS, and adds:
- Linux and Windows desktop
- A native iOS and Android app
- Many more agents than OpenCode (Claude Code, Codex, Pi, plus 30+ more via the in-app ACP catalog)
- A scriptable CLI to drive agents and connect to remote daemons
Mobile
JCode ships a direct Android APK alongside its desktop and web clients. Download it from the JCode download page.
OpenChamber does not have a native mobile app.
Desktop
JCode ships on macOS, Linux, and Windows.
OpenChamber ships on macOS.
Providers
JCode runs Claude Code, Codex, OpenCode, and Pi natively, plus 30+ more agents through the in-app catalog including GitHub Copilot, Cursor, Gemini CLI, and Amp. JCode speaks the Agent Client Protocol, so any ACP agent works. Custom providers run any CLI agent. See Supported providers.
OpenChamber is built around OpenCode.
Panes
JCode's app has split panes and tabs (⌘D for vertical, ⌘⇧D for horizontal). Panes include a terminal alongside your agents, a diff viewer, and a browser for testing running services.
GitHub
JCode's app handles commit, push, opening PRs, watching checks and reviews, and merging.
CLI
JCode has a CLI that mirrors the app:
jcode run --provider codex "implement OAuth"
jcode run --host devbox:6767 "run the test suite"
jcode ls
jcode send <agent-id> "add tests"
jcode schedule create --cron "0 9 * * 1" "audit the codebase"
jcode run --host connects to a remote daemon. jcode schedule runs an agent on a cron. jcode loop retries an agent until a verification command passes.
OpenChamber does not have a CLI.
Worktrees and services
JCode runs each agent in its own git worktree. Each worktree gets its own dev server URL like web.fix-auth.my-app.localhost, so parallel agents don't fight for ports.
Voice
JCode's speech-to-text and text-to-speech run locally on your device. OpenChamber does not have voice.
