Frequently Asked Questions

Do I need a database like MySQL or PostgreSQL?

Nope! Calpal is completely self-contained. It stores all necessary data locally using SQLite embedded within the single Go binary, making backups as simple as copying a file.

Does it integrate with my actual calendar?

Yes! You can connect Calpal to Google Calendar and Microsoft Teams through standard OAuth. Calpal checks your ICS feed to block out times you're busy, and auto-generates video meeting links upon booking.

Can I customize the emails sent to my invitees?

Absolutely. Right from your dashboard settings, you can edit the global confirmation and cancellation email templates, or set custom templates per specific event type using dynamic tags like [Name] and [Time].

How much RAM does it use?

Because it's written in Go with no heavy runtime dependencies, Calpal idles around 15-20MB of RAM. It runs flawlessly on a Raspberry Pi or the smallest $4/month VPS you can find.
