In April, we launched the Vercel 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.
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.
