Do I need an API gateway if I'm only managing a few APIs?

Not necessarily.

If you only have a few APIs, an API gateway may be overkill unless you need one or more of these:

• Single auth layer across all APIs
• Rate limiting / throttling
• Request routing to multiple services
• Centralized logging / monitoring
• TLS termination
• API versioning or transformation
• Security policies like IP allowlists, JWT validation, etc.

When you probably don’t need one

You can often skip an API gateway if:

• You have just a few simple APIs
• They’re internal or low-traffic
• Each API is independently simple to expose
• You’re okay handling auth, logging, and routing in each service or at the load balancer level

When it’s still worth it

Even for a small number of APIs, a gateway can be helpful if:

• You expect to grow soon
• You want to avoid duplicating cross-cutting concerns
• You need consistent security and observability
• You want a cleaner public interface in front of multiple backends

Common lightweight alternatives

Instead of a full gateway, consider:

• A reverse proxy like Nginx, Traefik, or Caddy
• Cloud load balancer + WAF
• App-level middleware for auth/logging
• Direct exposure with good service design

Rule of thumb

If your current needs are just “route requests to a few endpoints,” a gateway is probably unnecessary.
If you’re starting to manage shared security, traffic control, or observability across services, a gateway becomes more valuable.

If you want, I can help you decide based on your setup (cloud/provider, number of services, auth needs, public vs internal APIs).
