Open source + great DX + responsive support always wins.

If you're selling stuff online and haven't tried @polar_sh yet — 100% recommend doing so!

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.

Amazing! Really excited to seeing how this turns out.

Polar is the cutting edge of how open source might be financed in the future.

Huge congrats to Polar, love what this team is doing. Three person team, executing like crazy.

Building the perfect solution at the perfect time in history.

There has never been a better time to build software, and now, there has never been an easier way to charge for the software you build.

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.
