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.

I came across Flowglad just a few weeks ago. I wish this had existed when I was building Diagram’s billing system.

I didn’t know metered billing could be this simple.

Big time saver as a solo-founder, integration was very quick.

Honestly, Flowglad has maybe been the best dev ex I've ever seen.

Founder and Head of Engineering, HDR
Just a couple lines of code and it works out of the box. Setting it up ourselves would’ve taken way longer.
