Vercel acquires Better Auth to accelerate open source auth
Why it matters
Vercel is betting that agent identity and access control will be foundational to the next generation of AI infrastructure. By acquiring Better Auth (4.7M weekly npm downloads), Vercel is positioning itself as the platform for building and deploying agents with granular, revocable permissions—a critical control layer as autonomous agents proliferate.
Key signals
- Vercel acquires Better Auth (open source authentication library)
- Better Auth: 4.7M+ weekly npm downloads, 850+ contributors
- Founder Bereket Engida and core team joining Vercel
- Better Auth library remains free and open source under MIT license
- Focus: Agent identity and scoped, revocable authority for autonomous agents
- Integration planned with Vercel Connect and Eve platforms
- Agent Auth Protocol being developed to limit and control individual agent permissions
The hook
Vercel just acquired Better Auth. Here's why agent identity infrastructure is the next battleground.
Vercel is acquiring , the company behind the open source , 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.Better AuthTypeScript authentication library

Better Auth applies it to authentication: framework-agnostic, runs anywhere, and gives developers auth they own.
When an agent acts on your behalf, it runs under your identity and access, so every service it touches sees you, not the agent. There's no clean way to limit what any one agent or subagent can do, or to shut down just one without cutting off the rest.
The Better Auth team has been building so that each agent can carry its own identity and its own scoped, revocable authority, with you as the single point of control. Agent identity is foundational to .Agent Authagentic infrastructure
