Cal.com (formerly Calendso) is the open source Calendly alternative. Self host it, or have it hosted by us. Integrate it seamlessly into your business with advanced customization and the open API.
Designed to be a joy to use for you and your visitors.
Me, Peer, and hundreds of others have been looking for a more powerful calendar scheduling solution to replace Calendly. One that is customisable, integrates with anything, is white label and more. So, we decided to create our own.
We've had over 500 people sign up on our early access list, and we already have an awesome community around Calendso. We're super happy to be finally launching it!
We believe that nothing should stand between connecting humans and scheduling important events. That's why Calendso is open-source and available to everyone, for free. Our mission is to democratise and decentralise calendar scheduling, enabling everyone to be able to use calendar scheduling however they'd like.
For instance, booking a COVID vaccine shouldn't happen on a server in another country that somebody else is in control of. That's why Calendso enables you to self-host your calendar scheduling, so that your data belongs to you. This enables government bodies and healthcare organisations to use Calendso for their scheduling needs, as existing SaaS alternatives don't meet the compliance requirements.
What email has done to communication, we hope Calendso will do to meetings. We're here to make calendar scheduling work for absolutely everyone.
Super excited about the launch of Calendso by @baileypumfleet!
I couldn't hold back and made a video to explore the open source project and how to run it yourself:
I used Railway to spin up a quick development PostgreSQL and definitely will deploy it to Vercel and Railway for production.

@baileypumfleet This is amazing. Exactly what I have been thinking to build but could never find time. 🚀
Report
@baileypumfleet Great initiative, and really needed for country-specific sensitive data requirements.
@abram ya, the app looks fantastic and amazing that it's open-source, but this is a *glaring* miss for a calendar booking app. At no point in the UI does it even show the user what timezone they're selecting times in (and it's not their own unless they're in London, which is what they probably think it is).
Makes ya kinda wonder what else was missed, eh?
Report
@abram Someone already implemented this feature and made a PR couple of hours ago, so will not be a problem anymore.
@bacakad We believe that open source enables us to make calendar scheduling accessible to everyone, and we've had such good feedback from the open source community on this.

This is one of the coolest project out there. Was interacting with team in slack and they are amazing people. The best part of calendso is the UI. Sure that people will love this awesom eproduct.
Awesome!! #1 feature for me. I didn’t see it on the landing page - maybe that could be highlighted clearly somewhere
Report
Fantastic to see an open source alternative to the calendar/p2p-scheduling layer. The UI is great as well, but the main magic is being able to do deeper integrations. Can't wait to try it out.
@chrisdietr Absolutely, the ability to add completely custom integrations is one of the core principles of Calendso. We're working hard to build many more off-the-shelf integrations, but if you for instance wanted to add a custom integration with an LMS for instance, Calendso allows you to do that easily.
