What You're Actually Paying For With Vercel
Vercel charges for compute and bandwidth, but what you're really paying for is the operational layer: automatic SSL, preview deployments, edge caching, image optimisation CDN, and the Next.js integration that makes ISR and Server Components work without configuration. For a team of three shipping features, not managing infrastructure is worth a lot.
The Vercel pricing model works well at low-to-medium scale. It gets expensive as bandwidth or function invocations scale — this is well-documented and the common reason teams migrate away.
When Self-Hosting Makes More Sense
Self-hosting makes economic sense above a fairly predictable traffic threshold — usually around the point where Vercel costs exceed the cost of a managed Kubernetes cluster plus the engineer time to maintain it. For high-traffic, cost-sensitive applications, the maths usually favours self-hosting.
Self-hosting also makes sense when you need control that Vercel doesn't offer: specific compliance certifications, data residency requirements, custom network configurations, or integration with internal infrastructure that isn't internet-accessible.
Key takeaways
- Vercel is optimal for teams where developer time is the constraint — the zero-config deployment, preview URLs, and edge optimisation justify the cost at low-to-medium scale
- Self-hosting becomes economically rational above roughly $500-1000/month on Vercel — model your expected traffic and build a comparison before assuming one is better
- You can self-host Next.js on any Node.js server with 'next start' — all core features work, though you lose some Vercel-specific optimisations like automatic ISR revalidation infrastructure
Conclusion
The right answer depends on team size, traffic scale, compliance requirements, and how much you value not thinking about infrastructure. Neither is universally correct. The mistake is not questioning the default.
