Tymeslot vs Cal.com
Cal.com announced in 2026 that it is going closed-source: new versions are proprietary, and the only free self-hostable option is now cal.diy, a separate MIT fork scoped to personal use. Tymeslot stays source-available and self-hostable, with the complete product in every install.
Tymeslot or Cal.com?
Until 2026, Cal.com was the best-known open-source scheduler — AGPLv3 and self-hostable, with a deep API. That changed: Cal.com moved its production code closed-source (v4.x was the last AGPL release), so new versions are proprietary. The free self-hostable option is now cal.diy, a separate MIT community fork scoped to personal, non-production use that drops teams, organisations, SSO, workflows and routing forms. Tymeslot is the source-available alternative that keeps what people came to Cal.com for: self-hostable end to end, CalDAV-first, EU-based, one Elixir app plus Postgres, flat pricing, and the complete product free to self-host.

What you gain by switching
Simpler to run
Tymeslot is a single Elixir/Phoenix app plus Postgres: one container, a five-minute setup, sensible defaults. Self-hosting Cal.com means running its full Next.js stack and infrastructure.
Simpler to use
Tymeslot is built for non-technical users: set up event types and a booking page without touching code. Cal.com is developer-first, with a steeper learning curve.
Flat pricing, not per-seat
Tymeslot Pro is a flat €9/month, and self-hosting is free with full feature parity. Cal.com's managed plans are billed per user, so cost grows with your team.
The full product when you self-host
Tymeslot's self-hosted build ships the complete product: payments, automation, themes, embeds and i18n, with nothing gated. Cal.com's own production code is now closed-source, so the only free self-host route is cal.diy.
The free fork is missing what teams need
cal.diy, the MIT community fork, is scoped to personal, non-production use and drops teams, organisations, SSO/SCIM, workflows, routing forms and analytics. Tymeslot self-hosts the whole product, teams included, for free.
Profession-tuned out of the box
Tymeslot ships ready-made booking flows and guidance for specific professions — coaches, therapists, photographers and more — rather than a blank, build-it-yourself platform.
Tracker-free booking pages
Tymeslot booking pages load no third-party advertising or analytics pixels, and connected calendars only ever expose busy/free — never event details.
Tymeslot or Cal.com — the real differences
For a long time this was the comparison where the headline differentiators cancelled out: both open source, both self-hostable, both CalDAV, both EU. That stopped being true in 2026. Cal.com moved its production code closed-source, so new versions are proprietary, and the only free self-hostable option is now cal.diy — a separate MIT fork scoped to personal use that drops teams, organisations, SSO, workflows and routing forms.
So the four things people came to Cal.com for no longer all hold. Tymeslot keeps every one of them: source-available under the Elastic License 2.0, self-hostable end to end with the full product included, CalDAV as a first-class provider, and EU hosting or self-host anywhere. On top of that it is the smaller stack (one Elixir app and Postgres), a five-minute setup, and flat pricing instead of per-seat.
Choose Cal.com, or its paid cloud, if you want its developer platform and large API and don't mind a proprietary production codebase. Choose Tymeslot if you want scheduling you can still self-host in full, for free, with your data and the source in your hands.
Which one is right for you?
No tool wins for everyone. Here's how they split.
Choose Tymeslot if…
- You want source-available scheduling that's simple to run and simple to use
- You prefer flat pricing over per-seat billing
- You want every feature included when self-hosting — nothing behind a separate licence
- You're not a developer and don't want to build on an API to get going
Choose Cal.com if…
- You're an engineering-led team that wants a deep scheduling API to build on
- You need Cal.com's extensive app store and routing/workflow ecosystem
- You want Cal.com's large ecosystem and are fine with a proprietary production codebase (or the personal-use cal.diy fork)

Switching from Cal.com to Tymeslot
Tymeslot vs Cal.com — common questions
Is Tymeslot or Cal.com easier to self-host?
Tymeslot is the lighter option: a single Elixir/Phoenix app plus PostgreSQL, deployable via Docker, Cloudron or Railway in roughly five minutes, with the full product included. Cal.com's production code is now closed-source, so the free self-host route is cal.diy (MIT, personal use), which runs the full Next.js stack and leaves out teams, SSO and workflows.
Is Cal.com still open source?
Not for its production product. In 2026 Cal.com moved its production codebase closed-source; v4.x was the last AGPL release, and newer versions are proprietary. The remaining free, self-hostable option is cal.diy, a separate MIT community fork scoped to personal, non-production use that drops teams, organisations, SSO, workflows and routing forms. Tymeslot's core is source-available under the Elastic License 2.0 (free to use and self-host; commercial redistribution needs an agreement), and its self-hosted build ships the whole product with nothing gated. (Cal.com licensing as of 2026 — verify at cal.com.)
How does pricing compare?
Tymeslot Pro is a flat €9/month (€90/year) regardless of team size, with a free plan and free self-hosting. Cal.com's managed plans are billed per user ($12/user/mo Teams and up, billed annually), so cost scales with headcount.
Do both support CalDAV calendars?
Yes — this is one area where Tymeslot and Cal.com agree. Both sync two-way with generic CalDAV servers in addition to Google and Outlook, so Nextcloud, Fastmail and mailbox.org users are well served by either.
Which should a non-technical user pick?
Tymeslot. It's built so anyone can set up event types and a booking page without code, and ships profession-tuned booking flows out of the box. Cal.com is developer-first, with a steeper learning curve.
