Happy to clarify, but hard to give exact numbers. First, Next.js – we invest into our core team and also growing that community (events, supporting creators, etc). It's a major investment for us. Then, we have a bunch of other open-source libraries and frameworks that we support, like SWR, SWC, webpack, and friends. We also sponsor and support frontend frameworks like Nuxt, Astro, Svelte, etc (through OpenCollective and GitHub Sponsors) as well as giving free Vercel accounts to teams like tailwindcss.com! Finally, we hired Rich Harris (creator of Svelte) to work on Svelte full-time and grow that open-source community.
