Vercel Open Source Program: Winter 2026 cohort
In April, we launched the Vercel Open Source Program (https://vercel.com/open-source-program) to give maintainers the resources, credits, and support they need to ship faster and scale confidently. The first group joined through our spring 2025 cohort (https://vercel.com/blog/spring25-oss-program). Today we are welcoming the winter 2026 cohort. From AI-native apps and developer infrastructure to design systems and creative tooling, open source builders continue to amaze us. Meet the creators and explore their projects.
