Vercel is a hosting and deployment platform aimed squarely at frontend teams. You connect a Git repository, and from then on every push produces a build and a live URL. Merges to your main branch go to production; every other branch and pull request gets its own preview deployment on a unique address that stays up for as long as the branch does. That single mechanic is why most teams adopt it, because it turns "can you show me what this looks like?" from a half-hour of local setup into a link pasted in a comment.
The platform is built by the team behind Next.js, and the integration between the two is the deepest on offer anywhere. Framework features land on Vercel first and tend to work without configuration: server components, streaming, incremental static regeneration, image optimisation and middleware all deploy without a build file. That tight coupling is both the main argument for Vercel and the main argument against it, depending on how much you mind a hosting decision and a framework decision being made together.
Vercel is not Next-only. It detects and builds Astro, Nuxt, SvelteKit, Remix, Vite and static output, and it runs serverless and edge functions in Node, Python, Go and Ruby. Requests are served from a global edge network with automatic caching, so a static page is fast worldwide without you configuring a CDN. Environment variables, custom domains, TLS certificates and rollbacks are all handled in the dashboard or the CLI, and a deployment can be promoted or reverted in one click, which matters more during an incident than any amount of build speed.
Where teams run into trouble is cost at scale and the serverless execution model. Pricing is usage based across bandwidth, function invocations, function duration and build minutes, and a site that suddenly gets attention can produce a bill that is difficult to predict in advance. Long-running work does not fit: functions have execution limits, so background jobs, video processing and anything holding a connection open belong somewhere else. Teams commonly run the frontend on Vercel and put queues, workers and databases on infrastructure priced by the hour.
Who it suits: frontend and full-stack teams shipping web applications who would rather not run infrastructure, and who value preview deployments enough to pay for them. Who should look elsewhere: teams with heavy background processing, strict cost ceilings, or a requirement to run in a specific region or on their own hardware. The free tier is genuinely usable for personal projects and is how most people start, but read the fair-use terms before putting anything commercial on it.
