Syncplug

SyncPlug puts your Syncthing sync status in your Chrome toolbar so you never have to wonder if your files are up to date.

A colour-coded icon tells you everything at a glance:
- Green — all folders synced, all devices connected
- Yellow — syncing in progress, no errors
- Red — errors detected, failed items, or a device disconnected
- Blue (spinning) — actively transferring files

Click the icon for a quick status panel showing folder states, connected devices, and out-of-sync item counts. One click opens your Syncthing Web UI.

Connects to your local Syncthing instance via its REST API. All communication stays on localhost — no data is collected or transmitted externally.

Requires a running Syncthing instance and your API key (found in Syncthing settings under General).
