Self-hosted or hosted by us. White-label by design. API-driven and ready to be deployed on your own domain. You are in control of your events and data.
Start accepting bookings
Calendso gives you greater control and was designed to be as versatile as possible — design and modify it your way. Once you start using it, you start wondering how you previously coped without it.

Built for teams that need more control
Let’s face it: Calendly and other scheduling tools are awesome. It made our lives massively easier. We’re using it for business meetings, seminars, yoga classes and even calls with our families. However, most tools are very limited in terms of control and customisations.
For most teams, scheduling is a core part of the product. We get rid of any design restrictions that come with alternatives.
Integrate Calendso with your platform using our open API, built in customisation options and range of embed options.
100% in Control
You are in control of your events, your customer data and your costs. Calendso can fit your needs, any way you want.
Say hello to unlimited customization.
When the classic iframe embed isn’t enough, you might want to try Calendso. Design, modify and adapt it your way.
Open to anyone. Fork it, twist it. Flip it.
Join the community and help us build the best open source communications protocol for humans.
This open source project was born during #ODF6 and we’re committed to give developers, small businesses and enterprise the power to connect with anyone and make friends or business.
Build it your way.
In 2021, entire businesses run on top of scheduling software. Serve your customers better with custom extensions, build by you. Send an invoice after someone scheduled a meeting? Done. Send a follow up reminder after 7 days? No problem. Build it your way.
No foreign branding. It’s about you.
Calendso is whitelabel by design, regardless of if you use our hosted solution, or self-host it.
Confidently build Calendso into your business, while still maintaining your own branding to customers.
Connect to the services you love.
Calendso comes with plenty of integrations, as well as the ability to build custom integrations for any platform out there. Calendso is designed to work anywhere in your business.

The right choice for small startups to enterprise or goverment agencies.
Open source projects have been one of most important things for the early stage ecosystem and enable startups to grow without massive monthly costs.
Dealing with sensitive user data can become a problem with third-party SaaS providers. Uptime reliability is another reason to trust in your own hosted instances.
For government & healthcare
An easy self-hosting solution is even more important for government agencies and healthcare providers than for most Enterprise companies due to high regulations about their technical infrastructure.

Our mission is to connect a billion people by 2031.
Making calendar scheduling work for everyone.
Ourselves 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 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.
