CalBridge: Two way calendar sync tool

Self hosted two-way Google Calendar sync tool

Visit site ↗Alternativestop 9% of February 2026

What it does

Unlike expensive SaaS tools ($8-48/mo), CalBridge is open-source and self-hostable for as low as ~$5/mo on a VPS or totally free if you run it on your machine. Key differences: granular copy controls (choose exactly what syncs), smart filtering by keyword or color before sync happens, true two-way sync with loop prevention, and bounded backfill control. Deploy in one click on Railway.
