Own your scheduling infrastructure—eliminate coordination emails and vendor lock-in while keeping full control of your data.

Small businesses and consultants waste 15-20 minutes coordinating every meeting through back-and-forth emails. Proprietary scheduling tools like Calendly charge $10-16 per seat monthly, lock your data into their platforms, and raise prices as you scale. You're paying indefinitely for infrastructure you could own.
Cal.com gives you professional scheduling automation without surrendering data sovereignty or accepting perpetual SaaS fees. Deploy your own scheduling infrastructure that integrates with any calendar system, automates booking workflows, and keeps every piece of data under your control. Perfect for privacy-conscious businesses, regulated industries requiring GDPR compliance, and anyone tired of recurring vendor fees for basic scheduling functionality.
Vaivatta deploys Cal.com for free on your infrastructure—you only pay for optional add-ons like backups or priority support. Get the same automated scheduling, team coordination, and workflow integration as $30/month SaaS platforms, but own it permanently. Break free from per-seat pricing that punishes growth and take control of your scheduling infrastructure today.

Frequently Asked Questions
Is Cal.com really free to deploy?
Yes. Cal.com is open-source software that Vaivatta deploys on your infrastructure at no charge. You own the scheduling system permanently. We only charge for optional add-ons like automated backups, SLA guarantees, or priority support. Unlike Calendly ($10-16/seat/month) or Acuity ($16-61/month), you'll never pay recurring per-seat fees just to keep scheduling.
What happens to my scheduling data?
You own it completely. Cal.com runs on your infrastructure with data stored in Finnish data centers under GDPR protection. Unlike proprietary SaaS platforms, you control who accesses your scheduling data, can export everything anytime, and never worry about vendors changing terms or selling customer information. Perfect for regulated industries requiring data sovereignty.
How much time does manual scheduling actually waste?
Studies show coordinating a single meeting takes 4-6 emails averaging 15-20 minutes of back-and-forth. If you schedule just 10 meetings weekly, that's 2.5-3 hours lost to coordination instead of productive work. Cal.com eliminates this completely with self-service booking—clients see your real availability and book instantly.
Do I need technical staff to run Cal.com?
Vaivatta handles deployment and initial configuration—no technical expertise required. Once running, Cal.com manages itself with automatic updates available. We offer optional maintenance packages if you prefer completely hands-off operation, but basic usage doesn't require IT staff. Much simpler than managing traditional business infrastructure.
Can I customize booking workflows for my specific business?
Absolutely. Unlike rigid SaaS platforms, Cal.com gives you complete control. Set buffer times between meetings, limit daily bookings, require advance notice, collect custom information during booking, integrate with payment processors, route appointments based on team expertise, and automate confirmations. You own the infrastructure, so you decide how it works.
What about the AGPL license—can I use this commercially?
Yes, commercial use is fully permitted. The AGPL license means Cal.com source code is transparent and you can modify it freely. If you distribute modified versions, you must share those changes, but simply using Cal.com internally for your business has no such requirement. This protects your freedom while ensuring the community benefits from improvements.
How does Cal.com compare to keeping my Google Calendar link?
Shared Google Calendar links expose your entire schedule to anyone with the link, offer no buffer time controls, lack professional branding, can't collect payments or custom information, and provide zero analytics. Cal.com gives you professional booking pages, automated workflows, team coordination, integration capabilities, and complete control—while still syncing with your Google Calendar.
What are the risks of self-hosting scheduling infrastructure?
You're responsible for uptime and security updates, though Vaivatta can handle this through optional maintenance packages. Calendar API changes might occasionally require configuration updates. Limited vendor support compared to managed SaaS options. However, you gain permanent ownership, complete data control, no vendor lock-in, and zero recurring per-seat fees—benefits that outweigh maintenance responsibilities for most businesses.
