TL;DR: We are excited to announce that VoidZero is joining Cloudflare. Vite, Vitest, Rolldown, Oxc, and Vite+ will remain open-source and MIT-licensed. Evan and the rest of the VoidZero team will continue to lead these projects, with Cloudflare fully committed to supporting our mission.
I have been working on open source developer tools for over a decade. From 2016 to 2023, I worked as an independent developer. I started with Vue at the frontend framework layer, and ventured deeper into build tools with Vite. With the help of the community, we organically scaled Vue and Vite to millions of weekly downloads.
When I started VoidZero in 2023, the goal was to tackle a much bigger problem: building a fast, unified toolchain for the entire JavaScript ecosystem. It was clear that this vision required a dedicated full-time team, which would not be feasible with the sponsorship-based model I used for my previous projects. Raising venture capital was the most realistic way to make it happen, and so we did.
Fast forward to 2026, we have made a lot of progress:
- We kept improving Vite and Vitest, solidifying their roles as the default choices in modern JavaScript/TypeScript development. Today, Vite alone is downloaded more than 100 million times a week.
- To support Vite, we built Rolldown: a blazing-fast Rust bundler with esbuild feature parity and Rollup API compatibility. It is now the default bundler in Vite 8.
- Rolldown was built on top of Oxc, the JavaScript language toolchain written in Rust that powers all of our tools. In addition to bulletproofing and perf-tuning Oxc’s parser and resolver, we also implemented a full set of Babel-equivalent transforms and a minifier on top of it. The Oxc crates are now widely used outside of our own tooling as well.
- We shipped Oxlint, a linter with full ESLint plugin compatibility and true type-aware linting powered by tsgo, making linting in large projects 50–100x faster.
- We shipped Oxfmt, a formatter with full Prettier compatibility while being 30x faster.
- We shipped Vite+, the unified toolchain for TypeScript that can cover the whole development workflow from runtime management, project scaffolding, to building for production.
Despite the rapidly growing adoption of our tools, we haven’t yet solved monetization. Monetizing tooling, especially open-source software, has proven to be quite challenging. We experimented with a mixed licensing model for Vite+, but it didn’t feel right. Our conclusion was that we needed to sell a service with great synergy with our open-source tooling, without creating perverse incentives that distort our roadmaps and priorities. That is why we open sourced Vite+ under the MIT License and started working on Void, a Vite-native deployment platform built on top of Cloudflare.
However, working on Void presented its own issues: we had to split our already short-handed team into two, and building a cloud platform is a distinct domain compared to tooling. While we had plenty of runway, the road to scalable revenue remained long and filled with unknowns.
Enter Cloudflare
VoidZero and the Vite team had been collaborating with Cloudflare extensively on the Vite Environment API and Cloudflare’s Vite plugin before any acquisition talks began. Our experiment with Void made the synergy between the Vite ecosystem and Cloudflare even more obvious. By bringing the VoidZero team into Cloudflare, we can keep focusing on what we do best while helping make Cloudflare a better platform to deploy Vite apps on.
From Vue to Vite and VoidZero, the common theme of my work has remained consistent: helping developers become more productive. This fits naturally with Cloudflare’s mission to help build a better Internet. We also see a great alignment of values in acknowledging the importance of open source and the community. The most important condition for VoidZero to join any company was a full commitment to supporting all of our open-source projects in a way that respects their communities. Cloudflare is fully onboard with this. You can learn more about Cloudflare’s commitment and our next steps in their own announcement.
The timing is also perfect. With AI shifting the landscape, we are seeing more usage of our tools coming from AI agents. Our mission now includes building better tooling for agents, just as Cloudflare is positioning itself to become the cloud for agents. Together, we can build a coherent, frictionless, end-to-end experience for both developers and agents.
We believe this acquisition is a great fit for VoidZero both strategically and culturally, and we are excited for this new chapter.
Acknowledgements
I want to thank the VoidZero team for trusting me and joining me on this wild ride. I am very proud to have assembled such a talented team and even prouder of what we have built together. With that said, there is still so much more to do. We are just getting started.
Thanks to all our investors for believing in my vision, in particular Casey Aylward from Accel who led both our Seed and Series A.
Last but not least, I am deeply grateful to the Vite community. Vite and VoidZero wouldn’t have come this far without your trust and support. We will continue building with all of you, together, in the open.
