Frequently Asked Questions

Common questions about Vercel runtimes, limits, and deployment features.

What Node.js versions does Vercel support?

Vercel supports Node.js 24.x (default), 22.x, and 20.x for Serverless Functions. You can specify the version via the engines.node field in your package.json. Vercel automatically detects and uses the appropriate Node.js version for your project. Node.js 20.x is the minimum supported version as of 2026.

What's the difference between Serverless and Edge Functions?

Serverless Functions run on Node.js (or Python, Go, Ruby, Rust) in a single region with up to 300s execution time on Pro plans. Edge Functions run on Chromium V8 isolates across all regions simultaneously, with sub-millisecond cold starts but a smaller execution environment (Web APIs only, no Node.js built-ins). Use Serverless for heavy computation and database access; use Edge for lightweight request/response transformations, A/B testing, and geolocation-based routing.

Can I use Python/Go/Ruby on Vercel?

Yes. Vercel natively supports Python (3.9–3.12), Go (1.21–1.23), and Ruby (3.1–3.3) as Serverless Function runtimes. Place your function files in the /api directory with the appropriate file extension (.py, .go, .rb). Dependencies are installed automatically from requirements.txt, go.mod, or Gemfile respectively.

What are Vercel's free tier limits?

The Vercel Hobby plan (free) includes: 200 projects, 100 deployments per day, 1 concurrent build, 45-minute build timeout, 100 MB static file upload limit, 60-second function duration, 250 MB function size, 4 MB Edge Function size, and 100 GB bandwidth per month. It is intended for personal, non-commercial projects.

How does Vercel compare to Netlify?

Both platforms offer Git-based deployments, serverless functions, and edge networking. Vercel has deeper Next.js integration (as its creator), offers Edge Middleware, and supports more backend runtimes (Go, Ruby, Rust). Netlify offers built-in form handling, identity/auth, and a wider plugin ecosystem. Vercel's Pro plan ($20/user/mo) allows 6,000 deployments/day vs Netlify Pro's 500 builds/month. Choose Vercel for Next.js-heavy or multi-runtime stacks; Netlify for simpler Jamstack sites with built-in backend features.

Does Vercel support monorepos?

Yes. Vercel has first-class monorepo support for Turborepo, Nx, Lerna, pnpm workspaces, npm workspaces, and Yarn workspaces. You can configure the root directory for each project in the Vercel dashboard, and Vercel automatically detects workspace dependencies. Remote Caching with Turborepo is built-in on Vercel for faster builds.
