How we grade them
| 3.6GPACal.comExcellent | 3.2GPAOneCalVery good | |
|---|---|---|
| Value for money | BTeams is $12 per user a month billed yearly, $16 monthly. That's about the going rate for team booking tools, and a little over what a typical calendar app costs. SSO and sub-teams wait until Organizations at $28 a user. | BStarter is $5 a user a month billed annually, $6 monthly, and every plan gets the same features. What you pay for is calendars: 2 on Starter, 5 on Essential at $10, 50 on Premium at $25. Fair for two calendars, less so if you hold five clients' worth. |
| Free plan and trial | AFree forever for 1 user, with unlimited event types and calendars, email and SMS notifications, Stripe and PayPal payments and 100+ app integrations. A solo user could stay here for good. | CNo free plan. Every plan has a 14-day trial with no credit card required. When it ends, syncs are paused, the cloned events are removed and booking links are switched off until you buy a plan. |
| Features | ABooking pages, round-robin, managed and collective event types, routing forms, analytics, payments, CRM sync and its own video calls in Cal Video. Then an API, embeds and workflow automation for building it into your own product. | AOne-way or multi-way sync with control over which details get copied, unlimited one-on-one and collective booking links with workflows, one view to edit every calendar, and an AI assistant that changes nothing until you confirm. That's the job, covered in depth. |
| Ease of use | BWe have no App Store rating on record, so a B is the ceiling here. The hosted version is sign up and share a link. Self-hosting Cal.diy is another story, and Cal.com recommends it for personal, non-production use only. | BConnect your calendars and set up a sync in the web app. That's where the setup lives: in the mobile apps syncs are view-only and booking links can't be made or edited. No App Store rating on record, so a B at best. |
| Platforms and integrations | AWeb, Mac, Windows, Linux, iPhone, Android and a browser extension. It connects Google Calendar, Outlook, Zoom, Google Meet, Microsoft Teams, Salesforce, HubSpot and Stripe, and has an API. | AWeb, iPhone and Android, with Zoom, Teams, Google Meet and Zapier, plus an MCP server for Claude and ChatGPT. The Mac app is the iPad app, which the App Store limits to Macs with an M1 chip or later. |
| Best for | a booking page that's free for one person | stopping double bookings across several calendars |

Who each one suits
Cal.com
- Solo users who want unlimited event types without paying
- Developers adding scheduling to their own product
- Organizations that need SAML SSO, SCIM and compliance attestations
OneCal
- People whose work and personal calendars keep producing double bookings
- Consultants and freelancers holding calendars from several clients
- Teams that want calendar sync and booking links in one subscription
Worth knowing
Cal.com
- The free plan is limited to 1 user; shared team availability and round-robin scheduling need the Teams plan.
- Cal.com announced in April 2026 that its production code was going closed source. The open-source edition is now Cal.diy, without Teams, Organizations, Workflows or SSO.
- Cal.com recommends Cal.diy for personal, non-production use only; self-hosting the commercial product requires an enterprise license from sales.
- SAML SSO, SCIM and sub-teams start on the Organizations plan at $28 per user / month, billed yearly.
OneCal
- There is no free plan. When the 14-day trial ends, syncs are paused, cloned events are removed and booking links are disabled until a plan is bought.
- Starter connects 2 calendars per user and Essential 5. Removing OneCal branding from booking pages and dedicated support need Premium.
- In the mobile apps, calendar syncs are view-only and booking links cannot be created or edited; that setup is done in the web app.
- The macOS app on the plan table is the iPhone and iPad app, which the App Store marks as designed for iPad and limits to Macs with an M1 chip or later.
