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)

[Darcy Clarke @darcy]

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.

[Open Source Pledge ⇌ @ThePledge]

Welcome aboard to our newest member company ... at a whopping $12,000 per dev! Well done! 🐰👏😁

[CodeRabbit @coderabbitai]

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!

[Santosh Yadav @SantoshYadavDev]

Proud to announce we are joining @ThePledge at @coderabbitai we already committed more than $600,000 in year 2025, we will be paying this amount over the year since we started sponsorship, and we will continue doing more and wants to do $1M this year, the OSS funding is very close to my heart, so lets work together to make OSS more sustainable.
