How Baïkal is hosted

Valebyte launches the application automatically in a managed container. You receive its URL and application access, but not root access to the host system.

info Overview

Baïkal is a lightweight, open-source CalDAV and CardDAV server — it hosts your calendars and contacts on your own server and syncs them to any standard app you already use: Apple Calendar and Contacts, Thunderbird, DAVx5 on Android, Evolution and more. It is a privacy-friendly self-hosted alternative to Google Calendar and iCloud for keeping your events and address book under your own control.

Valebyte hosting model: Baïkal launches automatically as a managed application. Choose a region and resource plan; after checkout you receive the application URL and app-level access, normally within minutes. Valebyte maintains the host infrastructure. Root access to the host is not provided, and infrastructure backups are not enabled automatically.

quiz Frequently Asked Questions

Is Baïkal a good self-hosted Google Calendar alternative? expand_more
Yes. Baïkal hosts your calendars and contacts on your own server and syncs them to standard apps over CalDAV/CardDAV, giving you a private alternative to Google Calendar and iCloud with full data ownership.
Which apps can I sync with it? expand_more
Any CalDAV/CardDAV client: Apple Calendar and Contacts, Thunderbird, DAVx5 on Android, Evolution and others. You point them at your Baïkal server URL and your calendars and contacts sync automatically.
Does it sync contacts too, or only calendars? expand_more
Both. Baïkal is a CalDAV server for calendars and a CardDAV server for contacts, so your address book syncs across devices alongside your events.
How do I set it up? expand_more
On your first visit Baïkal runs a short setup wizard where you create the admin account, then you add your calendars and connect your devices by pointing each app at your server URL.
How long does deployment take? expand_more
A few minutes. Valebyte pulls the Baïkal image, issues an HTTPS certificate and starts it; then you open your site and complete the built-in setup wizard.
Is my data private? expand_more
Yes. Your calendars, contacts and user accounts live in your managed Valebyte application environment and are never shared with a third party. You control the application data.
