For a Next.js app specifically, a few platforms stand out from the rest of the field.

1. 1.Amazon Web Services — the default choice for teams that already run infrastructure there, with essentially unlimited configurability, though it takes real DevOps time to set up and keep tuned ¹
2. 2.Netlify — a close alternative with similar developer experience and a strong plugin ecosystem, particularly popular for static sites and Jamstack, though its serverless function limits are tighter than some competing platforms'
3. 3.Cloudflare — stands out for its global edge network and a genuinely generous free tier, though its framework-specific tooling is a step behind the frontend-first platforms ²
4. 4.Render — a simpler, more affordable option for smaller projects and side projects, with predictable pricing, though it lacks the edge footprint of the larger platforms

Any of the top picks will handle a Next.js app well out of the box — the choice mostly comes down to how much infrastructure you want to manage yourself.
