Vercel

Vercel is a hosting and deployment platform for web applications. Connect a Git repository and every push builds and deploys automatically, with a preview environment created for each one so a change can be checked at a real URL before it reaches production.

Deployments are unlimited, and the controls around them matter as much as the build itself. Rolling releases push a new deployment out incrementally rather than all at once. Rollbacks return to a previous deployment when something goes wrong in production. Deployment Protection keeps builds that are not meant to be public from being reached. Environments are managed separately for local, preview, production and custom cases, and environment variables are typed as either Config or Secret. Elastic build machines make use of Turborepo cache data.

Serving runs over a globally distributed delivery network with automatic routing, automatic compression, image optimisation and SSL/TLS. Pages support incremental static regeneration, refreshed on a schedule or on request. Functions scale dynamically and can be configured by region; on the Bun runtime they go up to 5GB in size and 30 minutes in duration. Private inter-region networking is available, as is Vercel Sandbox, which runs globally. A customisable web application firewall handles attacks and unwanted traffic through rules you set.
