Self-Hosted Cal.com for Your Whole Team, No Per-Seat Bill
Calendly charges $16 per user per month. Cal.com on Opsily is one flat fee, no matter how many people book meetings. We deploy it on EU servers, handle every update, and your booking data never touches a third-party cloud. You get a live booking link in minutes.
Why Teams Are Moving Off Calendly
The math stops working the moment your team grows. Per-seat SaaS billing punishes you for hiring, and your booking data ends up on servers you do not control.
The Per-Seat Bill Adds Up
Calendly Teams costs $16 per user per month, billed yearly. A 10-person team pays $1,920 every year just for scheduling. Cal.com cloud Teams is slightly cheaper at $12 per user, but that is still $1,440 per year for 10 seats. Opsily charges a flat monthly fee: add your 11th team member and your bill does not change. For teams of 5 or more, the savings cover the hosting cost within the first few months.
EU Hosting Costs $28 Per Seat on Cal.com Cloud
Cal.com cloud only lets you choose EU data hosting on their Organizations plan: $28 per user per month, or $3,360 per year for 10 users. That is not a feature you should have to pay a premium for. On Opsily, every plan runs on EU servers by default. There is no upgrade required for data residency. If your clients are in Germany, France, or anywhere in the EU, you are compliant from day one.
Your Booking Data is Not Yours on SaaS
When a prospect books a call, that record includes their name, email address, meeting topic, and timezone. That is personal data under GDPR Article 4. Calendly, Cal.com cloud, and Acuity all store this data on their own servers. You cannot inspect it, you cannot easily move it, and a vendor policy change can affect your access. On Opsily, the data sits in a PostgreSQL database on your own server. You own the export. You control the retention policy.
Built for teams who need reliability
What Self-Hosted Cal.com Actually Gives Your Team
Cal.com has 40,700 GitHub stars for a reason. It is not a stripped-down Calendly clone. It is a full scheduling platform with features that most teams never get to use because they are locked behind expensive SaaS tiers.
100+ Integrations, All Included
Cal.com connects to Google Calendar, Outlook, Apple Calendar, Zoom, Google Meet, Microsoft Teams, Stripe, PayPal, HubSpot, Salesforce, Zapier, Make, and Slack. That is over 100 integrations available on your self-hosted instance. None of them require an upgrade to a higher tier. Routing forms let you qualify and route leads before they land on your calendar. Webhooks let you trigger automations the moment a booking is created or cancelled.
Team Scheduling Without the Premium
Round-robin scheduling, collective events, and managed event types are all available on self-hosted Cal.com. On Cal.com cloud, round-robin requires the $12 per user Teams plan. On Opsily, your whole team uses every scheduling feature for the same flat fee. The recurring events, booking analytics, and dynamic group links (combine two team members into one booking URL) are included. No feature gating, no upgrade prompts.
Your Brand, From the First Plan
Cal.com cloud removes its own branding only at the $12 per user Teams tier. On a self-hosted instance via Opsily, your booking page shows your company name and domain from day one, on the entry-level plan. You can set a custom domain, apply your own CSS, and run white-label booking flows for clients. With 40,700 GitHub stars and 12,300 forks, Cal.com is the most widely adopted open-source scheduling tool on the market.

The Right Choice for Scheduling Data That Belongs to You
Every booking record contains personal data: a name, an email address, a meeting topic, a timezone. Under GDPR, you are responsible for where that data lives and who can access it. Opsily puts that control back in your hands.
GDPR-Ready by Default
Opsily deploys Cal.com on EU servers in every plan. No upgrade required for data residency. Your booking records never leave EU infrastructure, which satisfies GDPR Article 32 requirements for personal data at rest.
Your Data, Your Keys
Your PostgreSQL database is on your own server. Opsily does not have standing read access to your booking data. You control backups, retention, and exports. If you ever leave, you take a full database dump with you.
SSL and Uptime Managed
SSL certificates are provisioned and renewed automatically. Opsily monitors your instance and handles updates so you do not wake up to a broken booking page. Your team and your clients get a reliable, always-on scheduling experience.
EU Server Infrastructure
Every Opsily-hosted app runs on European servers. For businesses in Germany, France, the Netherlands, or anywhere in the EU, this is not optional: data processing agreements and GDPR compliance require it. Opsily makes it the default, not an upgrade.
Open Source, No Lock-In
Cal.com is MIT-licensed and has 40,700 GitHub stars. Your booking data lives in a standard PostgreSQL database. If you ever want to move to a different host, you can export everything and migrate in an afternoon. No proprietary formats, no locked exports.
