Zeron Control your coding agents (Claude Code, Codex, Cursor, Devin, Grok, Hermes, Pi, Antigravity) locally by default, with optional multi-device sync. English | 簡體中文 Every device runs a small engine that stores sessions on that device. A new installation starts in local-only mode without an account or a network connection. Install and run locally (Linux) curl -fsSL https://zeron.sh/install.sh | sh zeron status The installer starts the daemon immediately and keeps it running across reboots. No sign-in or sync configuration is required. The desktop sidebar browser also needs the Linux browser runtime . Day-to-day: zeron status # local/synced mode and engine status zeron update # update to the latest release zeron daemon start | stop | restart | status Optional multi-device sync Sign in only when you want to open your account's synced workspace. Authentication changes the profile selected by the next engine start, so stop the daemon before changing it: zeron daemon stop zeron login zeron daemon start You can then start an agent on one synced device and follow or drive it from another. An always-on machine such as a VPS can keep those agents working after you close your laptop. Devices signed in to the same synced account are trusted with remote workspace access. A device controlling a workspace on another device can list, read, and write its files; enabling Show ignored files also makes gitignored files such as .env available remotely. .git is always excluded. Only sign in devices you trust with the full contents of your workspaces. Signing in does not upload, move, or import existing local sessions. Local sessions and their attachments remain under the local profile and reappear when you return to local-only mode: zeron daemon stop zeron logout zeron daemon start zeron login and zeron logout refuse to modify credentials while an engine owns the data directory. The desktop app follows the same next-restart profile boundary. On macOS: use the desktop release, or build zeron from source and run zeron daemon install to install the launchd service. On Windows: extract the portable release ZIP and run zeron.exe . Keep zeron-update.json beside it for in-app updates. See the development notes for source builds.
