Cloudflare Workers vs Vercel Functions
Two edge runtimes for AI apps.
/ quick answer
Both run at the edge. Cloudflare is cheaper at scale and integrates with R2/D1/Vectorize; Vercel ships tighter with Next.js and the AI SDK. Two edge runtimes for AI apps.
| Dimension | Option A | Option B |
|---|---|---|
| Runtime | workerd (Cloudflare) | Node-compatible edge (Vercel) |
| AI data | Vectorize, Workers AI (Cloudflare) | External + AI SDK (Vercel) |
| Pricing | Cheap at scale (Cloudflare) | Higher (Vercel) |
| DX with Next.js | Good (Cloudflare) | Best (Vercel) |
- →High-volume, cost-sensitive AI APIs → Cloudflare
- →Next.js apps with tight DX → Vercel
