The Vercel Open Source Program is a developer initiative that provides resources, credits, and support to open source project maintainers. The program aims to help communities thrive by giving them the tools they need to ship faster and scale confidently. This spring's cohort of projects includes Vecto3d, Script Kit, Lenis, Fumadocs, Shadcn-table, Morphic, Zola, Valibot, shadcn-form, jsPDF, LobeChat, Milkdown, KokonutUI, nuqs, Nemo, RetroUI, Tweakcn, CourseLit, Comp AI, EsJS, Gridiron Survivor, and Frontpage. These projects are gaining popularity in their respective communities, with some having over 40K site visits or 1 million weekly npm downloads. The program welcomes a new cohort of projects four times a year, providing them with $3,600 in Vercel credits, perks from partners, and a dedicated Slack space to learn from one another.
