# Vercel Open Source Program: Spring 2026 cohort **Published:** June 29, 2026 | **Authors:** Amy Egan | **Category:** Community --- The world runs on open source software. The frameworks, libraries, and tools we rely on are made possible by communities that share ideas and build in the open. At Vercel, we want to help those communities thrive. That’s why we run the [**Vercel Open Source Program**](https://vercel.com/open-source-program): a developer initiative that gives maintainers the resources and support they need to keep shipping and growing their projects. Four times a year, we welcome a new cohort of open source projects into the program. Maintainers receive $3,600 in Vercel platform credits, a starter pack with credits from third-party services, and guidance from Vercel and the community. Today, we welcome a new cohort into the program. ## Spring 2026 cohort ### ASCII Studio A browser-based tool that converts video frames in real time into precise ASCII representations using an optimized rendering pipeline.
