Highlights

No walled garden

Open CalDAV syncs with the apps your team already uses, so your calendar is never locked to one client.

Meetings in one step

Drop a Meet room onto any event, and guests join straight from the invite with no account.

Made for distributed teams

Time-zone-aware events and shared team calendars keep everyone working off the same hour.

What you get

Everything in Calendar.

Part of the Bulwark webmail on Stalwart, built on open standards, hosted in the EU.

Answers

Calendar questions.

Does it work with the calendar app on my phone?
Yes. Calendar is open CalDAV, so it syncs natively with Apple Calendar, Thunderbird, DAVx5 on Android and anything that speaks the standard.
How do video meetings work from an invite?
One click adds a Meet room to the event; guests join from the link in the invite, no account or download required.
Can I share calendars with my team?
Yes, with shared team calendars and per-calendar permissions, all over open CalDAV.
