Calenday vs Cal.com
Cal.com is the open-source scheduler: a public repository, a real API and thousands of integrations, billed at $12 per seat per month. Calenday is a one-time $99 licence with unlimited users. If you want to read the source, Cal.com wins on the spot.

The short version
Both can be self-hosted. Cal.com is genuinely open source with an API and a large integration catalogue, but still bills $12 per seat per month, and separate brands sit on the $28 Organizations plan. Calenday costs $99 once and puts multi-brand isolation on the free plan.

Which one should you pick?
This one splits cleanly. If scheduling is a component you are embedding in your own product, Cal.com is built for that and we are not. If scheduling is a tool your team uses and you want the cost to stop growing, Calenday is the simpler answer.
| If you need… | Choose |
|---|---|
| A flat cost regardless of headcount | Calenday |
| Client brands separated without a $28 plan | Calenday |
| To be running in ten minutes without infrastructure work | Calenday |
| To read, fork and modify the source code | Cal.com |
| A public API to embed scheduling in your product | Cal.com |
| SAML SSO, SCIM and a compliance package | Cal.com |
| A large community and third-party plugins | Cal.com |
What each one costs over 36 months
Cal.com is priced here on Teams at $12 per seat per month, its cheapest paid plan. Sub-teams, a company subdomain and SAML SSO require Organizations at $28 per seat per month, which is $5,040 for five people over three years.
| Solution | Plan used | 1 person | 5 people | 20 people |
|---|---|---|---|---|
| Calenday | Lifetime | $99 | $99 | $99 |
| Cal.com | Teams · Teams · Teams | $432 | $2,160 | $8,640 |
Cal.com figures come from cal.com/pricing. Self-hosting is possible under the licence in their repository; the plan prices here apply to their hosted service.
What Cal.com does better
Cal.com is the stronger product on every axis that matters to a developer, and we are not going to argue otherwise. If any of the following is a requirement rather than a preference, stop reading and choose Cal.com.
It is actually open source
A public repository you can read, fork and audit. Calenday can be self-hosted, but its source is not published under an open licence. This is a real difference, not a marketing one.
A public API and developer platform
Cal.com is built to be embedded in someone else’s product, with API keys, webhooks and UI components. Calenday has no public API today.
A very large integration catalogue
Thousands of connected applications through their app store. Calenday connects to five services.
Enterprise compliance and identity
SAML SSO, SCIM, role-based permissions and published compliance work on the Organizations and Enterprise plans. Calenday has none of this.
A community
An active contributor base, public issues and third-party extensions. A single-vendor product cannot replicate that.
What Calenday does better
Three differences, all commercial or structural. Open source solves the question of who controls the code; it does not solve the question of what a growing team pays every month.
Open source is not the same as free
Cal.com Teams is $12 per seat per month — $2,160 for five people over three years, $8,640 for twenty. Calenday is $99 once, whatever the headcount.
Multi-brand without the top plan
Cal.com puts sub-teams and a company subdomain on Organizations at $28 per seat per month. Calenday isolates unlimited brands on the free plan.
Self-hosting without the project
Cal.com self-hosting means running and maintaining a substantial open-source stack. Calenday ships a Docker image and a Postgres schema; the operational surface is deliberately smaller.
Four languages, fully
English, French, German and Spanish across the dashboard, the public booking page and the transactional emails — not just the booking page.
Migrating from Cal.com
Straightforward, because the two models are close. Event types, availability schedules and booking pages map almost one to one, so the work is re-entering configuration rather than rethinking it.
What carries over automatically
- Your calendar, as soon as Google or Microsoft is reconnected.
- Existing meetings, which live in your calendar rather than in Cal.com.
- Contacts, through a CSV export and import.
What you have to redo
- Event types and availability schedules must be recreated, though the concepts match closely.
- Anything built against the Cal.com API has no equivalent in Calenday.
- Apps installed from the Cal.com app store have no equivalent unless they are Google, Microsoft, Zoom, Stripe or PayPal.
- A self-hosted Cal.com instance is a different deployment; the two cannot share a database.
Calenday vs Cal.com, in short
- Is Cal.com free if I host it myself?
- Self-hosting removes the per-seat fee but not the cost: you run the infrastructure, apply the updates and handle the failures. Some features are also tied to their commercial plans. Their repository licence is the authority on what self-hosting permits.
- Why choose Calenday over an open-source tool?
- Because open source and low total cost are different things. Cal.com Teams costs $2,160 for five people over three years; Calenday costs $99. If reading the source is a requirement, that argument does not apply and you should choose Cal.com.
- Does Calenday have an API?
- Not publicly, today. Calenday consumes webhooks from Stripe and PayPal but does not publish an outbound API for third-party developers. If your plan involves embedding scheduling in your own product, Cal.com is the correct choice.
- Which has the better free plan?
- They are close, and Cal.com’s is excellent: unlimited event types, unlimited calendars, payments included. Calenday matches the unlimited event types and calendars, and adds unlimited separated brands — which Cal.com places on its $28 Organizations plan.
- Can both be self-hosted?
- Yes, with different effort. Cal.com is a large open-source application you deploy and maintain. Calenday ships a Docker image against a Postgres database. Cal.com gives you more control; Calenday gives you less to operate.
- Which is better for an agency?
- Calenday, on structure and price. Separating client brands is what an agency needs first, and Calenday does it on the free plan while Cal.com does it on Organizations at $28 per seat per month.
