Cal.com
Open-source, fully customizable scheduling software for individuals, teams, and developers
Cal.com is a scheduling app used by over a million people to eliminate booking back-and-forth. Share a link, and Cal.com handles calendar syncing, timezone detection, reminders, and video calls through Zoom, Google Meet, Microsoft Teams, or its own Cal Video. It works just as well for simple 1-on-1 meetings as it does for a full automated scheduling system with routing forms, round-robin distribution, and reminder workflows for teams. It supports payments via Stripe/PayPal, integrates with 100+ apps (Salesforce, HubSpot, Slack...), embeds anywhere, and — being open source — can be self-hosted or deeply customized by developers building their own scheduling platform.
