Buildout Schedule vs Cal.com
Cal.com is the developer favorite — a generous free tier and a real API. It is also a different product since April 2026, when the codebase went from open source to proprietary.

Where Cal.com is strong
The free tier is the most generous in the category — unlimited event types, calendars, and workflows. Developers get a real REST API, webhooks, and embeddable React components for building custom booking flows. If you are embedding scheduling inside your own product, their platform tier is built for exactly that.
Where we differ
Cal.com’s most common complaints are setup difficulty and a settings maze — it is a tool built by developers that expects some developer in you. Buildout Schedule is built for the operator: pick a template, get a working Rep Card, Schedule Page, and session types in one pick, and edit from there. And the identity Cal.com sold — open source you could trust and self-host — ended in April 2026 when the main codebase went proprietary. If that was your reason for picking them, the reason is gone.
Common questions
Is Cal.com still open source?
The main codebase went proprietary in April 2026. The old code was forked as Cal.diy under MIT for personal, non-production use.
Does Buildout Schedule have an API like Cal.com?
Not a public one today. If you need scheduling embedded in your own product with a full API, Cal.com’s platform tier is the stronger pick. If you need scheduling that runs your business out of the box, that is what we build.
How does setup compare?
Cal.com’s top review complaints are complex settings and setup difficulty. Buildout Schedule starts from a vertical template — one pick creates the Rep Card, Schedule Page, and session types, and you edit from there.
