What is Crab Fit?

Crab Fit is a free, open-source scheduling tool where you create an event, share the link and let everyone paint their available times on a grid. It converts time zones automatically and shows a heatmap of when most people are free, with no sign-up needed for anyone.

Pros: what Crab Fit does well

  • No accounts for anyone
  • Clear availability heatmap
  • Handles time zones automatically

Cons: where it falls short

  • No calendar syncing
  • Basic compared with full booking tools

Who Crab Fit is for

Groups planning a meeting, class or get-together who need to find a shared free slot.

Who can skip it

People who need paid bookings, reminders or calendar integration.
