Like the rest of the internet, Sentry runs on Open Source. Like the rest of the @opensourcepledge.com companies, we also believe in paying it back. In 2025, we gave out $750k to the OSS projects we rely on; here’s a sampling of some of them, and why they are so crucial 🧵

@thepsf.bsky.social supports the ubiquitously-used Python ecosystem, and earlier this year they admirably withdrew a $1.5m grant proposal on ethical grounds. But all their work can't be done for free, which is why this year we're giving them $16,750 and our thanks! 💌

@vite.dev has revolutionized JS bundlers through its quick builds and intuitive dev server⚡ Beyond that, it's also become the foundation for other excellent technologies like Astro. We use Vite all the time, which is why we gave them $4,361.53 this year

@svelte.dev helps us build snappy and accessible websites. Its small learning curve and lightweight size make it a great middle ground between vanilla JS and heavier frameworks. We're giving Svelte $3,380.71 this year to show our gratitude for their work 🌟

@apache.org supports a whopping 394 projects, so when show-stopping vulnerabilities like Log4Shell happen, they're one of the first to step in to help. Without them, the internet would be a scarier place. This year we're giving them $10,000, along with our full gratitude 🙏

Compared to higher-faff frameworks, @astro.build's performance and ease of use is a breath of fresh air, which is why we choose it time and time again. We gave Astro $2,161.58 this year and made sure the Astro ⇌ Sentry integration works out of the box 💫
