Polar is the financial layer for a new generation of intelligent software.
What industry leaders think about Polar
From AI startups to infrastructure veterans, the teams building the future ship production billing on Polar in days, not weeks.
Polar's Python SDK and Webhook infrastructure made our billing integration straightforward.
It gave us production-ready billing in hours, not weeks.
It's rare to find a vendor that moves this fast.
The speed at which Polar is executing on the financial infrastructure primitives the new world needs is very impressive.
I've joined Polar as an advisor!
I think it benefits everyone for devs to have more options to get paid to work on their passions, to support upstreams, and for users to have more confidence/transparency in the software they're supporting/purchasing.
I switched to Polar a few weeks back. Best decision ever.
We switched to @polar_sh because of their killer API, UX, and product. Also love that it's Open-Source. Their team cares A LOT as well. Worth the minor fee difference.
You can tell @polar_sh is building DX first
