## What it is
API Umbrella is an open source API management platform that sits as a layer above existing web service APIs. It standardizes access control, rate limiting, analytics, API keys, and unified documentation without requiring changes to the underlying API code.

## Use cases
- expose multiple backend APIs behind a single unified endpoint
- add API key authentication and rate limiting to existing APIs without code changes
- provide a self-service API key signup portal for public government or data APIs
- aggregate analytics and usage metrics across disparate APIs
- centralize API documentation for a multi-service API platform
- proxy and unify APIs written in different languages on different servers

## When to choose
- you need a full API management layer (keys, rate limits, analytics, portal) in front of existing services
- you want to unify heterogeneous APIs under one endpoint and credential system
- you run public data APIs and want self-service onboarding for consumers
- you prefer a self-hosted, open source alternative to commercial API gateways

## When to avoid
- you only need simple reverse proxying without API management features
- you want a lightweight gateway embedded in a modern service mesh or Kubernetes-native stack
- your team is unwilling to operate a Ruby/OpenResty-based self-hosted platform
- you need deep cloud-vendor integration offered by managed API gateways
