"Just use Vercel" has become the default answer for deploying Next.js apps. But does it actually make financial sense at scale? We deployed identical applications to both Vercel and Netlify for 90 days and tracked every cost, performance metric, and operational friction point.

The Test Setup

We deployed three application types to both platforms simultaneously:

Cost Breakdown: 90 Days

On the free tier, both platforms handled our static blog without issue. The differences emerged with dynamic applications:

Author's Case Study: The historical Neo Genesis static-site setup kept hosting costs low because SSG pre-rendered large content sets at build time. That reduced serverless execution costs for content-heavy surfaces. This is cost evidence, not revenue proof.

Performance

Edge function latency was nearly identical (both use Cloudflare under the hood for static assets). The meaningful difference was in cold start times for serverless functions: Vercel averaged 180ms, Netlify averaged 220ms. Not significant for most applications, but noticeable for our real-time recommendation endpoints.

Our Verdict

For Next.js applications with SSG-heavy architectures, Vercel's free tier is hard to beat. For teams using non-Next.js frameworks or needing more build customization, Netlify's flexibility gives it an edge. Full data and methodology are available on deploystack.neogenesis.app.
