It's a booking platform for your business or team. Clients pick a time from your calendar, book instantly, and get a confirmation email with a calendar file attached. You get notified. Everyone shows up on time.
The difference? It runs on free cloud services. No monthly fees. No contracts. If you can click "deploy" on a website, you can run OpenSchedule.
