Vercel is acquiring Better Auth, the company behind the open source TypeScript authentication library, which has 4.7M weekly npm downloads and more than 850 contributors.

Founder Bereket Engida and the core team are joining Vercel to continue their work on Better Auth and agent identity.

The library remains free and open source under MIT, retains its name, and the team continues to lead development with the same open contribution model, community governance, and framework support across the ecosystem.
