Cal.com pulled the open-source licence on the main app in favour of a licence that ringfences AI vendors, and a portion of the community moved fast to start shopping for alternatives. The new licence is more restrictive than the AGPL it replaced, which means commercial users and AI labs are reconsidering their options. These seven Cal.com alternatives cover the spread, from polished commercial replacements like Calendly to genuinely open-source picks that keep self-hosting on the table.
Why people are looking past Cal.com
The most recent licence change is the headline reason, but several frustrations had been building before that.
- The licence shift removes the easy story Cal.com had with developer-first teams who liked the AGPL guarantees.
- Self-hosting got more complex over the past year as the codebase added AI features and integration glue that need extra services to run.
- Pricing on the cloud plan crept up in 2025, with the Team plan adding a per-seat floor that priced out smaller agencies.
- App marketplace coverage is wide but some integrations (Hubspot, Pipedrive) feel like afterthoughts compared to Calendly.
- Mobile clients have always lagged the web app: features land on the web months before they reach the Android app.

The alternatives
Calendly — best polished commercial alternative
Calendly is the standard the rest of the category measures against. Round-robin scheduling, group events, paid bookings, Zoom and Google Meet auto-creation, and a marketplace that covers Salesforce, Hubspot, Slack, and the major calendars. The Android app holds parity with the web version for booker management and is the best mobile client in the category.
The product line was extended in 2024 with Routing Forms and Workflows that automate follow-ups and reminders without an outside automation tool.
Where it falls short: Pricing climbs fast at the Team and Enterprise tiers. No self-host option. Embeds outside the native widget can look dated.
Pricing:
- Free: One event type, basic integrations.
- Paid: Standard plan around the price of two coffees per user per month, Teams adds a multi-user surcharge.
- vs Cal.com: Pricier on paid tiers, no self-host, far more polished.
Migrating from Cal.com: Calendly imports ICS feeds and connects to Google or Outlook calendars directly. Event types do not auto-migrate; a 30-link migration takes about an hour.
Bottom line: Pick this if mobile polish and integrations matter more than self-hosting.
Microsoft Bookings — best for Microsoft 365 customers
Microsoft Bookings ships inside Microsoft 365 Business plans, which is the cheapest path for any team already on that licence. Bookings calendars surface directly in Outlook, Teams meeting invites generate automatically, and staff schedules pull from Microsoft 365 user data. The mobile app gives staff a place to manage appointments without opening Outlook.
The 2025 Copilot integration adds suggested booking times based on email context, though the feature is gated to higher tiers.
Where it falls short: Cal.com’s developer-friendly API and webhook coverage is much deeper. Outside the Microsoft stack the integrations dry up. The UI is dated by 2026 SaaS standards.
Pricing:
- Free: Not standalone.
- Paid: Included in Microsoft 365 Business Standard and above.
- vs Cal.com: Effectively free if you’re already paying for Microsoft 365.
Migrating from Cal.com: Booking services map cleanly to Cal.com event types, but the data does not auto-import. Manual rebuild for service definitions, then import staff calendars from Outlook.
Bottom line: Get this if Microsoft 365 is already paid for.
Acuity Scheduling — best for service businesses
Acuity Scheduling by Squarespace targets practitioners with clients: stylists, therapists, coaches, consultants. Intake forms collect medical or briefing info before the call. Payments and packages ship in the product so you can sell sessions through the booking page. Class scheduling and recurring appointments are first-class features.
It hooks into Squarespace sites natively, which is a big shortcut for solo operators who run their entire web presence there.
Where it falls short: No free plan. Mobile app trails the web app for new features. Pricing per practitioner can stack up for larger studios.
Pricing:
- Free: No free plan; trial available.
- Paid: Emerging plan a couple of times the cost of Calendly’s basic tier, Growing and Powerhouse plans add staff and class capabilities.
- vs Cal.com: More expensive, much richer for service-business workflows.
Migrating from Cal.com: Intake forms and payments have no direct import. Calendars and event durations can be rebuilt quickly. Plan a few hours.
Bottom line: Pick this if you book clients with intake forms and accept payments at the door.
Zoho Bookings — best for the Zoho One ecosystem
Zoho Bookings earns its slot the same way Microsoft Bookings does: as part of a wider productivity bundle. Zoho One subscribers pick it up at no extra cost. The hook to Zoho CRM, Desk, and Campaigns is the differentiator, since a booking can trigger a lead creation, a help-desk ticket, or a follow-up campaign without an external tool.
The free tier handles a single user with basic features, which makes it credible for solo consultants who don’t want a paid product.
Where it falls short: Outside the Zoho stack the integrations are thin. Workflows are not as flexible as Calendly’s Routing Forms.
Pricing:
- Free: One user, one workspace.
- Paid: Per-user monthly, lower than Calendly’s standard tier.
- vs Cal.com: Cheaper for a small team if you stay inside Zoho, no self-host option.
Migrating from Cal.com: Import iCal feeds, then rebuild service types. Map workflows to Zoho Flow if you want CRM triggers.
Bottom line: Get this if Zoho One is in the stack or your team already uses Zoho CRM.
TidyCal — best lifetime licence
TidyCal by AppSumo is the answer for solo operators who hate recurring SaaS bills. It ships a working booking system with multiple meeting types, Google and Outlook calendar sync, Zoom integration, and Stripe payments for paid bookings. The differentiator is the price model: a one-time lifetime fee rather than a monthly plan.
The product was acquired by AppSumo in 2022 and has continued shipping updates since, including a mobile app in 2024.
Where it falls short: Team features are limited compared to Calendly. The integration list is shorter. UI polish trails the bigger names.
Pricing:
- Free: Basic single calendar.
- Paid: A one-time lifetime fee that lands below a year of Calendly Standard.
- vs Cal.com: Cheapest total cost of ownership for a solo user willing to pay once.
Migrating from Cal.com: Calendar sync is automatic. Service types and durations are a manual rebuild.
Bottom line: Pick this if you don’t want a subscription and can rebuild your event types once.
Doodle — best for group poll scheduling
Doodle does the one thing the others avoid: it polls a group for availability before booking the meeting. Send a list of times, let invitees vote, then auto-create a calendar invite for the winning slot. It also offers standard 1:1 booking links for personal scheduling.
The pivot back to its poll roots in the past two years made the product feel like itself again after a period of trying to compete head-on with Calendly.
Where it falls short: Workflow automation is shallow. Team management is basic. The poll mechanic is unique but not what most scheduling buyers ask for.
Pricing:
- Free: Single user with ads and basic polls.
- Paid: Pro plan at a lower monthly cost than Calendly’s Standard.
- vs Cal.com: Different category. Use for group polling, not 1:1 scheduling primary.
Migrating from Cal.com: Doodle is best used alongside another booking tool, not as a full replacement.
Bottom line: Get this when group polling matters more than 1:1 booking pages.
Easy!Appointments — best open-source self-host
Easy!Appointments is a PHP-based open-source scheduling app that you self-host on any LAMP stack. It is the closest thing to a like-for-like swap for Cal.com if licensing is the reason you are leaving. Service definitions, providers, customer database, Google Calendar sync, and a clean public booking page are all in the box. The codebase is GPL-3.0 and is genuinely maintained.
There is no commercial cloud tier and no mobile app, but the public booking page is responsive and works in mobile browsers.
Where it falls short: Self-hosting overhead means you need a server, a domain, and a maintenance plan. No dedicated mobile app. Workflows are basic compared to Calendly.
Pricing:
- Free: Self-host, no licence cost.
- Paid: Not applicable.
- vs Cal.com: Genuinely free of charge under a permissive licence and free of AI-licence restrictions.
Migrating from Cal.com: Service types rebuild quickly. Customer data exports from Cal.com as CSV and imports into the customer database with light cleanup.
Download: Self-hosted; see the project’s official site for installation instructions.
Bottom line: Pick this if licence-freedom and self-hosting are the actual reasons you are leaving Cal.com.

What is the best self-hosted Cal.com alternative?
Easy!Appointments is the strongest open-source self-host option for teams that need a booking page without a SaaS dependency. The codebase is GPL-3.0 licensed and runs on any LAMP server.
Can I import my Cal.com data into another scheduling app?
Most tools accept iCal feeds, which preserves the bookings on your calendar. Service definitions and event types usually need manual rebuilding. Customer data exports from Cal.com as CSV and imports into Easy!Appointments and most commercial alternatives.
Why did Cal.com change its licence?
Cal.com replaced its AGPL licence with a more restrictive licence in 2025 that limits redistribution to AI model training providers. The change applies to the main repository.
Is Calendly better than Cal.com?
For most teams that just want a hosted product, Calendly is the safer pick: longer track record, more integrations, the strongest mobile app in the category. Cal.com is better if you want open-source ethos or self-hosting under the old AGPL.
