What Flowglad is building is going to go somewhere. It’s actually good. I love that it’s open source. The objects are nice and clean.

Questions?

What does “payments without webhooks” mean?

You do not need to build webhook handlers or any glue code to keep entitlements in sync with your customer’s billing state according to your payment provider. Flowglad handles the webhook-driven state transitions internally and exposes the latest derived state via our SDK.

Who processes payments?

Currently Flowglad processes payments through Stripe.

Can I migrate my existing Stripe account over to Flowglad?

Absolutely. Reach out to our team ([email protected]) and we’ll work with you to migrate over your existing customers and billing to Flowglad.
