Hosted Baikal: a lightweight CalDAV and CardDAV server that keeps your calendars and contacts in sync, privately.

Early Access

This app is a brand-new addition to ElfHosted, and is considered beta. It runs, we test it, and your trial lets you prove it fits before you commit, but our support team does not yet have deep experience with it. Expect some trial and error: lean on the upstream documentation, experiment freely, and share what you learn in Discord, where the community and team are figuring these new apps out together. If you need a battle-tested workflow today, our established apps are the safer pick.
