Vercel

Vercel has become the deployment platform of choice for agencies building modern web applications, particularly those working with Next.js and React. The developer experience is exceptional: push code to Git, and Vercel automatically builds, tests, and deploys it to a global edge network in seconds. For agencies managing dozens of client websites, this automation eliminates the DevOps burden and lets developers focus on building rather than deploying.

The preview deployment feature is where Vercel delivers particular value for the agency workflow. Every pull request and branch automatically gets its own live URL that can be shared with clients for review. Instead of staging environments that are perpetually out of date, clients can see and interact with exactly what will go live. This speeds up the approval cycle dramatically and reduces the miscommunication that comes from reviewing static mockups versus live, interactive sites.

Compared to alternatives like Netlify or traditional cloud hosting, Vercel offers tighter framework integration, especially with Next.js (which Vercel created). The trade-off is some degree of vendor lock-in — features like Incremental Static Regeneration and Edge Middleware work best on Vercel's platform. Agencies should also be mindful of traffic-based pricing: a viral marketing campaign or unexpected traffic spike can lead to surprise bills. For most agency use cases, though, Vercel's combination of speed, simplicity, and polish makes it hard to beat.
