Cal.com
Open source scheduling with team routing, and self-hostable
1/2Cal.com is an open source scheduling tool: you publish booking pages that read your connected calendars, and people pick a slot without agreeing a time by email. The free tier covers unlimited event types and calendars for one person, and paid tiers add the team side — round-robin, collective and managed event types, routing forms that direct bookings, recurring events and booking analytics. It integrates with over 100 apps, syncs two ways with Salesforce and HubSpot, takes Stripe and PayPal payments at the point of booking, and imports existing Calendly events in one click. Because it is API-first the booker can be embedded inside another product, and the whole thing can be run on your own infrastructure instead of Cal.com's cloud.

What people are saying about Cal.com
34% positive“Well yeah they want to sell you something so they downsell their free option. Doesn't mean it's actually unsuitable.”
“The main ones you hear about are Calendly on the subscription / commercial side, and then 'Cal.com' as the alternative to Calendly. However, the self-hosted version of 'Cal.com' explicitly states in the README, "Use at your own risk.”
“No shows cost you zero dollars, because you have no business, and Booksly, Calendly, Cal.com, and every other booking app already has built in features to prevent this.”
