Score breakdown
Cal.com has public source and self-managed deployment paths; score reflects the expected operating footprint for scheduling.
A self-hosted deployment keeps primary data under operator control, with migration and backup quality depending on the deployment design.
Privacy posture depends on configuration, telemetry, retention, and integration choices documented or implied by the public project materials.
The project exposes standard web, API, protocol, or integration surfaces appropriate to scheduling.
The score reflects maintenance burden, release maturity, and the operational complexity implied by running this class of software.
It can be deployed in an EU-controlled environment; procurement fit still depends on support, contracts, accessibility, and hosting choices.
Ownership and development are publicly visible through the linked project materials, but governance depth should be reviewed before procurement.
