Skedz

Offline-first schedule viewer running entirely on your device.

Skedz is a Progressive Web App (PWA) for event schedules. It downloads a schedule once, stores it locally, and lets you filter, search, favorite, and export sessions – even without a network connection.

About Skedz

Why it exists

Skedz started as a small experiment during 39C3 – inspired by the schedule experience of Calendify – to see whether a congress schedule could work fully offline, without accounts or servers.

What it does

  • Load schedules from a URL or local file
  • Filter by day, room, track, type, language + search
  • Heart sessions to build your own schedule
  • Export to iCal / download your selections

What it is not

Skedz is not a platform. It does not require accounts, and it does not track you. Your data stays on your device unless you explicitly export it.

  • XML – Pentabarf / Frab / Pretalx schedule.xml
  • xCal – XML iCalendar format
  • iCal / ICS – standard iCalendar format

Built by the community

Skedz is intentionally hackable. Ports, integrations, and other side projects are welcome. If you build something around Skedz, we're happy to list it here.

Troubleshooting

Some schedule servers block browser access due to CORS (Cross-Origin Resource Sharing).

In this case you can:

  1. Download the file and import it via “Import file”.
  2. Use a CORS proxy such as cors.skedz.org.

Example using the Skedz CORS Proxy (FOSDEM 2026 schedule):
