Which one to pick
Cal.com 48,395 stars
Next.js with PostgreSQL. A close feature match for Calendly; the calendar OAuth setup is the fiddly part of the install.
At 10 people it needs 2.6 GB of memory and 10.5 GB of disk, which fits the Starter 4 GB at VPSServer for $22.00 a month. Setting it up is roughly 6 hours of work, then 1.5 hours a month to keep it healthy. Licence note: AGPL-3.0 core with some enterprise features under a separate commercial licence.
