Vercel deploys applications from GitHub, GitLab or Bitbucket and creates a preview URL for each branch. It supports Next.js with zero configuration and more than 40 other frameworks, and runs server code through Functions and routing middleware.
Beyond hosting it provides security features (a web application firewall, bot management, deployment protection), observability, instant rollback, and AI tooling such as the AI SDK, AI Gateway and Sandbox for running untrusted code.
It suits front-end and full-stack teams that want managed infrastructure. Usage beyond the included amounts on paid plans is billed pay-as-you-go, so costs depend on traffic and compute. The free Hobby plan is limited to personal, non-commercial use.
