KeepSync by Lachlan

KeepSync keeps your browsing in sync across browsers using a self-hosted server you control. No third-party cloud, no telemetry, no accounts.

Features:
- Tab sync — Your open tabs appear across all paired browsers in near real time.
- Bookmark sync — Full bookmark tree synchronization, preserving folder structure and ordering.
- History sync — Recent browsing history is merged so nothing gets lost when switching devices.
- Device pairing — Pair new browsers via invite tokens (first device) or in-app pairing codes (subsequent devices).
- Self-hosted server — A single Go binary with SQLite. Run it on a Raspberry Pi, VPS, or your home NAS.
- Privacy-first — All data stays on your server. No external services, no tracking, no accounts. The extension source is fully auditable.

Quick start:
1. Deploy the server (see GitHub for Docker, systemd, or bare-metal instructions).
2. Install the extension in your browsers.
3. Point each browser at your server and pair them.

KeepSync is free and open source (MIT). Contributions and feedback are welcome on GitHub.
