Vercel has acquired Grep, the code search tool that indexes over 500,000 public git repositories, to strengthen its developer tooling and AI efforts. Grep founder Dan Fox will join Vercel’s AI team, where he will continue developing Grep specifically for code search. The deal aligns with Vercel’s broader push to help developers build and release software more quickly.

Why engineers reach for Grep

Grep is designed for three common developer needs:

  • Debugging: search for an error message and locate where it is thrown across a large body of code
  • Learning: find concrete usage examples of a new function or API before building with it
  • Getting started: pull up relevant snippets to bootstrap a project or feature without starting from scratch

For example, a React developer who wants to update state from a form action and is considering useActionState can enter the hook name in Grep. Within moments, they get hundreds of similar implementations to model their own code after.

Example of searching for useActionState.

What the acquisition means next

Dan Fox joining the AI team signals that code search is a focal point for product development. The stated direction is to go beyond simple text indexing, using the acquisition as a foundation for more advanced, intelligent search capabilities built directly into the developer workflow.

Grep is available now at grep.app.
