When building makes sense

Consider an internal build for a personal booking workflow or a licensed deployment that covers your actual requirements. The latest research distinguishes Cal.diy’s personal scope from Cal.com’s commercial production code. Verify the current license and feature set before treating an old OSS deployment guide as evidence.

When buying makes sense

Buying earns its keep when you need team scheduling, routing, workflow, identity integration, and operating support. Compare the vendor’s coverage with the staff, integrations, and controls an internal option would need. Custom extensions can remain useful without replacing the core.
