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.
The speed at which Polar is executing on the financial infrastructure primitives the new world needs is very impressive
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!
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.
I've been integrating Polar recently and had a fantastic experience! Great DX and the team responds to support super quickly!
I finally tried @polar_sh after all the hype, and it's hands down the smoothest, most developer-friendly, and straightforward payment integration out there.
Amazing! Really excited to seeing how this turns out.
Polar is the cutting edge of how open source might be financed in the future.
I've been waiting for this so hard. LFG, congratulations on the launch guys!
I just saw the plugin and oh my god
