prev vs Vercel: Preview Deployments Compared

Vercel and prev both create preview deployments for web projects, but they take very different approaches. This comparison covers the key differences so you can pick the right tool for your team.

What Vercel Does

Vercel is a frontend cloud platform, originally built by the creators of Next.js. It provides hosting, serverless functions, edge middleware, and automatic preview deployments for every Git push. Vercel is deeply optimized for React and Next.js projects.

Vercel Strengths

• Next.js-native: First-class support for Next.js features (App Router, Server Components, ISR, middleware)
• Automatic preview deployments: Every push to a branch gets a unique URL
• Global edge network: Fast, globally-distributed hosting with edge functions
• Analytics and monitoring: Built-in web analytics and performance monitoring
• Team collaboration: Comments directly on preview deployments
• Generous free tier: Free for hobby projects and personal sites

Vercel Limitations

• Framework-centric: While it supports other frameworks, Vercel is heavily optimized for Next.js; other stacks get fewer features
• No Docker support: You can't deploy arbitrary Docker containers
• Serverless-only backends: Backend logic is limited to serverless and edge functions
• Platform lock-in: Using Vercel-specific features (edge config, KV storage, image optimization) ties you to the platform
• Pricing at scale: Costs can grow quickly for high-traffic or team projects
• Preview scope: Previews are only for projects deployed on Vercel

What prev Does

prev is a preview environment tool that deploys any web project — regardless of framework or hosting provider — to an isolated cloud container. You get a unique URL that stays live until it expires.

prev Strengths

• Runs anything: Node.js, Python, Go, Ruby, PHP, Rust, .NET, Docker — if it serves HTTP, prev can preview it
• No hosting lock-in: Use prev for previews while hosting production anywhere
• Full backend support: Deploy complete server applications, not just serverless functions
• Docker-native: Bring your own Dockerfile for full control
• Simple pricing: Flat plans based on environments, not compute usage or bandwidth
• CLI-first: One command from anywhere — local, CI/CD, scripts

prev Limitations

• Preview-only: Not a production hosting platform
• No built-in commenting: Preview URLs are for sharing, not collaborative annotation
• Manual CI/CD setup: You add prev to your pipeline yourself (typically 2-3 lines of YAML)
• No edge network: Previews are served from regional containers

Side-by-Side Comparison

When to Use Vercel

Vercel is the right choice when you:

• Build with Next.js: If your project is a Next.js app, Vercel provides the best deployment experience available
• Want zero-config hosting + previews: Connect your repo and get production hosting plus preview deployments automatically
• Need a global edge network: For performance-critical frontends that benefit from edge rendering
• Use Vercel-specific features: Edge middleware, KV storage, image optimization, web analytics

When to Use prev

prev is the right choice when you:

• Run a full-stack application: If your project has a backend server (Express, Django, FastAPI, Rails, Go, etc.), prev previews the entire application
• Use Docker: prev handles any Dockerfile natively
• Work outside the Next.js ecosystem: If you're building with Django, Rails, Laravel, Go, or any non-JS framework, prev supports it
• Want hosting-independent previews: Keep your preview tooling separate from where production runs
• Need simple, predictable pricing: Flat plans rather than usage-based billing
• Want to replace staging infrastructure: Spin up ephemeral preview environments instead of maintaining staging servers

Using Both Together

A practical pattern for Next.js teams:

• Vercel hosts and previews the Next.js frontend
• prev provides preview environments for backend services, APIs, or microservices that the frontend depends on

This gives you Vercel's optimized Next.js experience for the frontend, while prev handles the full-stack preview environments that Vercel can't deploy.

Conclusion

Vercel is a hosting platform built around the Next.js ecosystem with preview deployments as a core feature. prev is a dedicated preview environment tool that works with any web project, any framework, and any hosting setup.

If you're all-in on Next.js and want a single platform for hosting and previews, Vercel is hard to beat. If you need preview environments for backend services, Docker-based projects, or anything outside the Vercel ecosystem, try prev.
