Your coding agents, kept local until you say otherwise

What it does

Zeron installs a small daemon on your machine that acts as a local dashboard and session store for coding agents like Claude Code, Codex, and Cursor. Every installation starts in offline mode: no account, no network handshake, no cloud dependency. You get a CLI to check engine status and a desktop sidebar for visual oversight.

The interesting bit

The architecture treats “local” and “synced” as separate profiles rather than an afterthought. Existing local sessions never get uploaded when you sign in; they simply reappear when you sign back out. If you do sync, you can start an agent on a VPS, close your laptop, and drive it from another device—though the README notes that synced devices get broad remote file access, including gitignored files if you enable that option.

Key highlights

• Runs fully offline by default; no credentials or network required to start
• Daemon-based engine with CLI lifecycle management (start, stop, status, update)
• Optional multi-device sync with session handoff between machines
• Remote workspace access for synced devices, with .git always excluded and .env optionally exposed
• Local and synced profiles are strictly separated; logout restores local-only sessions

Caveats

• The desktop sidebar requires a separate Linux browser runtime installation
• macOS users must use the desktop release or build from source; no one-line installer is provided
• Synced devices are trusted with full workspace read/write access, including gitignored files if enabled, so the README explicitly warns: only sign in devices you trust

Verdict

Worth a look if you juggle multiple machines or want to park long-running agents on a VPS while steering from your laptop. Skip it if you are happy with each agent’s native interface and have no need for cross-device orchestration.
