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.

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.
Be like @coderabbitai. Sponsor OSS maintainers. 🙌
Support for more Open Source projects coming soon 😍
I love doing this, its amazing that @CodeRabbit cares so much about OSS and I can collaborate with all this amazing projects and OSS maintainers

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

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!
