Alternative to timeful.app (formerly schej.it) for volunteer org scheduling meetings?

Schej.it was an excellent, easy to use solution for our volunteer nonprofit to schedule meetings for our teams with a robust calendar import feature for availability. But a while ago they implemented a new feature that restricted the number of schedulers that could be created unless you had premium.

Are there any other free alternatives for schedulers that:

• don't require an account
• offer sync/import features if you do make an account
• user friendly and looks better than when2meet and other bare-bone solutions
• accounts for different timezones well

Potentially if it's affordable maybe look into discounted nonprofit price professional options too? We primarily work with the Google suite and Discord for communication
