ProtonScheduler is the open-source Calendly alternative that stores your data in your own Solid Pod. No tracking. No harvesting. Just meetings.
Built on the Solid protocol — the decentralized data standard created by Tim Berners-Lee. Your data stays yours, by design.
Sign in with Solid-OIDC. Your identity is portable — not locked to our platform. Works with any Solid identity provider.
Every booking, event type, and preference is stored in your personal Solid Pod. We never touch it. You grant granular access.
Get a clean booking page at your subdomain. Visitors pick a time, you get notified. Calendar syncs via CalDAV. Done.
A complete scheduling platform — without the surveillance business model.
15-minute calls, 1-hour consultations, recurring standups — create any event type with custom durations and buffers.
Two-way sync with Proton Calendar, Nextcloud, or any CalDAV provider. Avoid double-bookings automatically.
Your colors, your logo, your subdomain. Remove the ProtonScheduler badge on Pro plans for a fully white-labeled experience.
Trigger workflows when bookings are created, canceled, or rescheduled. Connect to Zapier, n8n, or your own backend.
Round-robin and collective scheduling for teams. Each member keeps their own Solid Pod — privacy preserved for everyone.
Automated confirmations and reminders via email. Works beautifully with Proton Bridge for end-to-end encrypted emails.
Detects visitor timezones automatically. Shows availability in their local time. No more "wait, is that EST or PST?"
Your scheduling data stored in a W3C-standard Solid Pod. Fully portable, fully encrypted, fully yours.
See which event types are popular, peak booking times, and no-show rates. All processed locally — no third-party analytics.
Same features, fundamentally different approach to your data.
