For those who know Sentry, you know we’ve been giving back to Open Source maintainers since our early days. This year, we increased our budget from $750,000 to $1,000,000. Here’s where it went 🧵

We just sent $100,000 to 20 open source projects ($5000 each) that the Syntax team use regularly and depend on. Thank you so much to all the maintainers for all your time and efforts! Big thanks to @sentry and @ThePledge for giving us the resources to do this. blog.sentry.io/another-year-…

this is how it's done 👇👏 do you know a company that should join next? put them in the replies!
ScreenshotOne is now officially a member of the Open Source Pledge (opensourcepledge.com/). Thanks, Zeke, for the suggestion to join. The pledge will help me be more systematic and intentional about supporting open-source maintainers and projects I value and want to see thrive. If you run a software company that relies on open source, consider joining too.

in times like these, I'm very happy that @sanity_io put some of our @ThePledge dollars on the good folks at @pnpmjs 🫡 (and we made it our mandated package manager internally)

I tip my hat to everyone out there that is doing the thankless, unpaid work to ensure their environments & software stays safe/secure. At @vltpkg we're giving back (ex. @ThePledge) & building a package manager that attacks the last mile problem with a zero trust approach. – at Mississauga, Ontario

Welcome aboard to our newest member company ... at a whopping $12,000 per dev! Well done! 🐰👏😁
Open source quietly powers everything from your terminal to your favorite frameworks, yet maintainers are often underfunded. In 2025, CodeRabbit distributed over $600,000 directly to OSS maintainers, and we’re just getting started!
