Functionality

Production-grade API gateway features for routing, traffic, and observability

Free 30 minutes Demo

## What API gateway functionality is included?

DreamFactory behaves as a production-grade API gateway in front of your services and data APIs: reverse proxying with path- and header-based routing, URL rewriting, health checks with load balancing and failover, and traffic protection through rate limits, quotas, throttling, and request size limits.

Request and response caching reduce load and latency, while centralized logs, metrics, and traces provide complete visibility into API behavior.

## How does DreamFactory behave as an API gateway?

DreamFactory runs as an API gateway in your environment, or behind your existing API gateway, providing core API functionality for routing, traffic management, and observability over every data API. The DreamFactory AI data gateway keeps the gateway, policies, and analytics close to your systems so you can shape and monitor traffic without rewriting back-end services.

### Core API gateway features

Reverse proxying, routing, and transformation across services and data APIs

### Resilience and availability

Health checks, load balancing, and failover to keep APIs online

### Traffic shaping and protection

Rate limits, quotas, throttling, and size limits at the edge

### Caching and performance

Response and request caching to reduce load and latency

### Observability and analytics

Central logs, metrics, and traces for complete API functionality visibility

## Reverse Proxy and Smart Request Routing

DreamFactory works with your production environments to route, secure, and manage API traffic across backend services.

### Reverse proxy

Forward client calls to internal services and hide their locations

### Path-based routing

Direct requests to the right backend or version based on URL structure

### Header-based routing

Use headers and metadata to steer traffic between services

### URL rewriting

Adjust paths and query strings at the gateway without changing back-ends

### Header manipulation

Add, remove, or modify headers for security, routing, and observability needs

## Resilience, Health Checks, and High Availability

DreamFactory's API gateway features help keep data APIs and services resilient even when individual components fail.

### Load balancing

Distribute traffic across multiple backend instances for performance and stability

### Health checks

Probe gateways and services to drive routing and failover decisions

### Failover and high availability

Switch traffic automatically when instances or zones go down

### Safe rollout patterns

Support blue/green or similar strategies as you evolve APIs behind the gateway

## Traffic Management and Protection

DreamFactory shapes, prioritizes, and limits API traffic as part of its core API gateway features.

### Rate limiting

Cap how many requests a client can make in a given window

### Throttling

Slow or temporarily restrict traffic when thresholds are exceeded

### Quota management

Enforce daily, monthly, or plan-based consumption limits

### Request size limits

Block oversized payloads that could harm downstream systems

## Caching and Performance Optimization

These gateway features reduce load on back-end systems by caching work where it makes sense.

### Response caching

Serve repeat requests from cache instead of re-hitting services

### Request caching

Reuse upstream results for identical calls keyed by parameters

### Tunable cache behavior

Configure cache keys, TTLs, and invalidation rules at the gateway layer

## Observability and API Analytics

DreamFactory collects usage, performance, and error metrics for APIs and exposes them through logging and analytics so you can see how your AI data gateway is behaving in real time.

### Request and response logging

Capture detailed call data for debugging and audits

### Real-time analytics

Monitor traffic levels, latency, and error rates across services

### Distributed tracing

Follow requests across microservices to find bottlenecks and failures

### Standard telemetry

Export metrics via Prometheus and OpenTelemetry into your observability stack

### Custom dashboards and alerts

Build views and alerts on key gateway and API functionality metrics

## Frequently asked questions

### Can DreamFactory route to existing backends, not just generated APIs?

Yes. As a reverse proxy it forwards client calls to internal services with path- and header-based routing and URL rewriting — backends stay hidden and unchanged.

### What keeps APIs available under load?

Health checks, load balancing, and failover keep endpoints online, while rate limits, quotas, and throttling protect backends from abuse and traffic spikes.

### What observability is built in?

Central logs, metrics, and traces across all APIs, providing the analytics and audit visibility operations and compliance teams need.
