Serverless API Gateway vs. Hand-Rolled Cloudflare Workers

The short answer: Hand-rolled Workers make sense when the API behavior is highly custom; this gateway makes more sense when the team wants a reusable, documented baseline for routing, CORS, auth, and transformation.

When to read this

• You are deciding whether to build or adopt.
• You want to reduce bespoke edge code.
• You need a baseline that new contributors can understand quickly.

What matters in practice

• Owning less custom routing code often speeds teams up.
• A shared config model is easier to document and review than ad hoc request logic.
• Custom Workers still win when the product behavior is unlike a gateway.

Concrete example

    | Decision area | Serverless API Gateway | hand-rolled Cloudflare Workers |
  | --- | --- | --- |
  | Deployment shape | Cloudflare Worker-native | Depends on hand-rolled Cloudflare Workers platform |
  | Inspectability | Open repo and config schema | Varies by platform |
  | Current built-in auth surface | JWT, Auth0, Supabase | Varies by platform |
  | Current feature breadth | Lean and focused | Usually broader |

The example above is intentionally small because the best gateway configs stay readable. Add only the route, auth, and mapping behavior you actually need.

How this maps to the current gateway

The current codebase already supports the behavior discussed here through its config schema, route matcher, and integration handlers. That is why this project is a good fit for reader-first examples: the docs and blog can point to real, implemented behavior instead of hypothetical gateway features.

What this product does not do

• This repo trades some flexibility for a clearer, repeatable contract.
• If every route has custom behavior, a dedicated bespoke Worker may be cleaner.

FAQ

Can I extend the gateway with custom Worker services?

Yes. The service and service-binding integration paths are exactly for that.

What is the main gain over custom code?

Consistency of behavior, docs, and testing around the common API concerns.
