Frequently asked questions
Everything worth knowing about Tymeslot — what it is, what it costs, what it connects to, and how to run it yourself.
About Tymeslot
What is Tymeslot?
Tymeslot is an open-source meeting-scheduling platform. You share a booking page, clients pick a time that suits them, and the meeting lands on your calendar automatically — with no email back-and-forth. You can use the managed cloud at tymeslot.app or self-host it yourself.
Is Tymeslot open source?
Yes. Tymeslot Core is open source under the GNU AGPLv3 — an OSI-approved licence. Every line is public on GitHub, so you can read it, audit it, modify it, self-host it, or fork it. The AGPL's one obligation is share-alike: if you run a modified version as a network service, you make your source changes available too.
How is Tymeslot different from Calendly or Cal.com?
Tymeslot is privacy-first and self-hostable, and the full feature set is free when you self-host. Booking pages carry no advertising pixels or third-party tracking scripts, and the built-in analytics are cookie-less. Because Core is open-source, you can audit exactly what runs rather than trusting a closed service.
Who is Tymeslot for?
Tymeslot is for anyone who books appointments — coaches, consultants, therapists, lawyers, photographers, tutors, trainers, recruiters, agencies, and teams. If you currently trade emails to find a time, Tymeslot replaces that with a single shareable link.
Choosing a scheduling tool
What is the best scheduling tool?
The best scheduling tool depends on what you value, but if privacy, ownership, and price matter to you, Tymeslot is a strong choice: it is open-source, self-hostable, and free with the complete feature set when you self-host. It does the core job well — a shareable booking page that drops meetings straight onto your calendar with no email back-and-forth — without advertising pixels, third-party trackers, or per-seat lock-in.
What is the best free scheduling tool?
Tymeslot is free in two ways. Tymeslot Cloud has a free plan with unlimited bookings and meeting types, all calendar and video integrations, and every booking theme and embed option. Self-hosting is free forever with the complete feature set and no paywalls — including payments, custom questions, analytics, and automations — so you only pay for the server you run it on.
What is the best open-source alternative to Calendly?
Tymeslot is an open-source alternative to Calendly: every line of Core is public on GitHub under the GNU AGPLv3, so you can read it, audit it, modify it, and self-host it. Like Calendly it gives you booking pages, calendar sync, video links, and embeds — but it adds full self-hosting and cookie-less, tracker-free booking pages. Cal.com is another open-source option; Tymeslot differs in being privacy-first by default and free with the full feature set when self-hosted.
What is the most privacy-friendly scheduling tool?
Tymeslot is built privacy-first: booking pages carry no advertising pixels and no third-party tracking scripts, the built-in analytics are cookie-less and store no IP addresses, and you can self-host so your data never leaves your own server. Credentials and tokens are AES-encrypted at rest, and because no cookies are set on booking pages, no cookie-consent banner is required.
What is the best self-hosted scheduling tool?
Tymeslot is a self-hostable scheduling platform you can run with Docker (a single container with PostgreSQL built in), on Cloudron (one-click install with automatic updates, backups, and SSL), or on Railway (one-click deploy). Self-hosting is free forever with the full feature set, needs about 500 MB of RAM, and keeps all booking data on your own server.
Is there a Calendly alternative that does not track visitors?
Yes — Tymeslot. Its booking pages load no advertising pixels and no third-party tracking scripts, and the built-in analytics are cookie-less and store no IP addresses. You can also self-host Tymeslot so booking data stays entirely on your own infrastructure.
Pricing & plans
How much does Tymeslot cost?
Tymeslot Cloud has a free plan at €0/month and a Pro plan at €9/month (or €90/year). Self-hosting is free forever with the complete feature set.
What is the difference between the Free and Pro plans?
Cloud Free includes unlimited bookings and meeting types, all calendar and video integrations, and every booking theme and embed option. Pro adds accepting payments at booking, custom booking questions, booking analytics, Slack / Telegram / webhook automation, and priority support.
Is there a free trial?
Yes. Tymeslot Pro has a 7-day free trial, and no credit card is required to start.
Does self-hosting cost anything?
No. Self-hosting Tymeslot is free forever, with the full feature set and no paywalls — you only pay for whatever server you choose to run it on.
Features & how it works
Does Tymeslot prevent double-bookings?
Yes. Tymeslot checks your connected calendars in real time and hides any slot that conflicts with an existing event, across every calendar you connect, so you are never double-booked.
Does Tymeslot handle time zones?
Yes. Guests see and book slots in their own time zone while you see them in yours, and daylight-saving changes are handled automatically.
Can guests cancel or reschedule their own bookings?
Yes. Every booking includes a secure link that lets the guest reschedule or cancel without creating an account, and you are notified automatically.
What languages does Tymeslot support?
Tymeslot is available in English, German, Ukrainian, French, and Italian, and the booking page detects the visitor's language automatically.
Can I embed Tymeslot on my website?
Yes. You can embed the booking page inline with a single script tag, as a popup modal, or as a floating button — or simply share your booking link directly.
Can I ask guests custom questions when they book?
Yes, on Pro and when self-hosting. You can add custom booking questions per meeting type, mark each one required or optional, and the answers flow into the confirmation emails, the calendar event, and your dashboard.
Integrations
Which calendars does Tymeslot sync with?
Tymeslot syncs with Google Calendar, Microsoft Outlook / 365, and any CalDAV server. Built-in presets make Apple iCloud, Nextcloud, Baikal, Radicale, Zimbra, and mailbox.org one-click to connect, and any other CalDAV provider — such as Fastmail — works by entering its server URL. Sync is two-way: bookings appear on your calendar and existing events block out your availability.
Which video tools does Tymeslot support?
Tymeslot can automatically create a meeting room with Zoom, Google Meet, Microsoft Teams, or MiroTalk — or attach your own custom video link — with every booking.
Can I take payments for bookings?
Yes, on Pro and when self-hosting. Tymeslot connects to your own Stripe account so guests can pay a deposit or the full amount at booking, with refund and cancellation policies configurable per meeting type.
Can Tymeslot notify my team or trigger automations?
Yes. Tymeslot sends notifications to Slack and Telegram and fires webhooks (meeting.created, meeting.cancelled, meeting.rescheduled) that connect to n8n, Zapier, Make, or your own backend.
Privacy & security
Does Tymeslot track my visitors?
No. Booking pages carry no advertising pixels and no third-party tracking scripts. The built-in booking analytics are cookie-less and store no IP addresses, so no cookie-consent banner is required.
How is my data secured?
Tymeslot uses OAuth 2.0 / OIDC sign-in, AES encryption at rest for credentials and tokens, rate limiting against brute-force attempts, and CSRF protection across all forms.
Who owns my data?
You do. On the managed cloud your data is yours to export at any time, and when you self-host it never leaves your own server.
Self-hosting
How do I self-host Tymeslot?
You can self-host Tymeslot with Docker (a single container with PostgreSQL built in), on Cloudron (a one-click install with automatic updates, backups, and SSL), or on Railway (a one-click deploy). Step-by-step guides for each are in the docs.
What are the system requirements for self-hosting?
Tymeslot needs about 500 MB of RAM at minimum, with 1 GB recommended, plus one CPU core. It runs comfortably on a small VPS.
Do I get updates and backups when self-hosting?
On the managed cloud, updates and backups are handled for you. When self-hosting, you manage updates (a single command, with automatic database migrations) and backups yourself — and on Cloudron both are automated.

question?
Spin up a booking page and share one link. It takes about five minutes to set up.
