Howdyyy PH-Community! 🤠
We're the team behind Recal - the headless infrastructure for everything calendar, especially building custom booking systems.
While most calendar tools force their UI on you, we believe developers should have complete control. Recal provides the calendar integration layer without any frontend constraints - just pure API/SDK that works with Google, Outlook, and other providers.
Whether you're building AI scheduling agents, custom booking flows, or enterprise appointment systems, you get the calendar backend without the baggage. Your UI, your rules, our reliable infrastructure running on Cloudflare's edge network.
Curious what booking experiences you're building! Happy to answer any questions about our architecture or integration approach :)
very hard problem you're on and looks promising! I think it could help if you can list all supported/not currently supported providers in the landing page & docs :)
Congrats on the launch!!
How long would it take to (re-)build a version of cal.com for my own scheduling?
Love that you are targeting AI scheduling agents bcz that space is growing very fast and most existing APIs are not built with that use case in mind . Great work 👏
Wow, unified API + SDK that handles calendars without forcing a UI — that’s a game changer for devs who want full control. Kudos to you guys! 🙌
nice nice nice! I used APIs like this before, and defo there is a big area to improve. which ICPs and marketers are you prioritizing first? there are tons of verticals i can think of!
Congrats! Why did you decide not to include any built-in UI components or templates for calendar interfaces, and do you see that causing challenges or friction for teams that want to move quickly?
It gives me that peace of mind knowing reminders and updates will actually run smoothly.
This tool honestly sounds like cheating... wish it would have launched sooner but better late than never.
would love to know if you’re planning to add native integrations for Apple Calendar in the near future. That would make it even more complete.
Love the “Resend but for calendars” framing, makes the value prop instantly clear.
I’ve wrestled with calendar integrations before, and it’s always painful. A unified API for Google, Outlook, and the rest is something I wish I had years ago.
