What is Keeper?

Keeper is an open-source tool for syncing and aggregating calendar events.

• Aggregate calendars — Combine events from multiple calendar sources into a single, unified feed.

• Privacy-focused — Event details are stripped, showing only busy/free times to protect your privacy. • Shareable iCal link — Generate a shareable iCal link that stays in sync with your sources. • Push events — Automatically push aggregated events to Google Calendar and other calendar services. • Self-hostable — You can run it on your own infrastructure. It's fully open-source under the AGPL-3.0 license.

It's built by Rida F'kih and the source code is available on GitHub. It offers a free tier for personal use and a paid tier for power users.
