Croodle at a glance
Checked 16 Oct 2026Croodle (214 stars, since 2013) runs date and general polls where all poll data is encrypted in the browser with AES-256. It needs only PHP 7.2+ webspace and stores data in text files, no database. MIT. The README still calls it alpha and "not meant for productive use yet"; the last tagged release is v0.7.0 (Aug 2023), though commits continue in Oct 2026. Only polls: no booking pages, calendar sync or payments.
RepoQuarry. “Croodle.” Checked 16 Oct 2026. https://repoquarry.dev/projects/croodleHow much of Calendly does it replace?
1 of 6 jobs. Encrypted date polls only; self-described alpha, no calendar integration.
For personal booking pages, calendar sync and availability, team round-robin and collective scheduling, payments for bookings, reminders, see other Calendly alternatives. You may also need to build an interface, an API server and hosting yourself.
