A unified platform for CalDAV and CardDAV management. Built for day-2 operations with production guardrails, sharing controls, and standards compliance.
Unified account model for web dashboard and DAV clients. Session-based web auth supports TOTP 2FA with backup codes. DAV uses HTTP Basic auth and supports app passwords for non-interactive clients when 2FA is enabled. Two roles: admin and regular.
New users are auto-provisioned with a default Personal Calendar and Contacts collection. Create and rename additional calendars and address books, mark them sharable, and export collection data.
Per-resource sharing with three permission levels: read-only, editor, and admin. Owner-managed sharing can be toggled by system admins. Global cross-user share assignments available.
Optional web UI for structured contact management with bi-directional vCard sync. Optional review queues support owner/admin approval workflows, including manual merge resolution when needed. Related-name family links are synced bidirectionally with inverse mapping and pronoun-aware labels, with neutral fallback when pronouns are not inferable.
CalDAV/CardDAV endpoints with autodiscovery redirects. Strict RFC-compliant validation by default with an admin-controlled compatibility mode for edge clients. Sync-token support for efficient incremental updates.
Production preflight checks, auth throttling, PostgreSQL advisory-lock bootstrapping for replica-safe startups, and deployment guidance for Railway and Coolify.
Built-in scheduled backup snapshots for calendars and address books with retention strategy controls for daily, weekly, monthly, and yearly tiers. Store locally, remotely on S3, or both, then restore with merge/replace modes and dry-run previews.
Address books can auto-generate and maintain dedicated birthday and anniversary calendars based on managed contact data, including combined couple anniversaries when relationships are mutually inferred.
Optional source mirroring lets selected address books mirror into a user's default contacts collection for improved Apple client visibility across the ecosystem.
Davvy runs as one Laravel application serving web UI, API, and DAV endpoints. Start with the Docker quick-start, then move to your preferred host.
