Features

Some of the features you get with KrakenD are:

• Ultra-High performance API Gateway
• Backend for Frontend
• Efficient: Super low memory consumption with high traffic (usually under 50MB w/ +1000 concurrent) and even lower with low traffic (under 5MB)
• Easy to use: Declaration of endpoints by just writing the /url/patterns/and/{variables}
• Unlimited number of backends and endpoints associated with each endpoint. The limit is your kernel.
• Aggregation of all the data in the backends for a single endpoint
• Response composition and data manipulation (capture, groups, renames...)
• Response filtering (whitelist and blacklist)
• Concurrent API calls to the backend for the same request
• Simple configuration: All application configuration and behavior declared in a krakend.json.
• Friendly: No development needed to build your gateway. Use the Visual API Designer (UI to generate the krakend.json)
• SSL
• HTTP2 ready
• Circuit breaker (fail fast and avoid smashing stressed backends)
• Bursting on High-load
• Logging and statistics of usage
• API with statistics
• Service Discovery: DNS SRV, ETCD or add your own
• Multiple encodings supported (json, XML, RSS or response as single string)
• Injections via DSL in the configuration (Martian)
• Throttling: Limits of usage in the router and proxy layers.
• User quota: Restrict usage of users by IP or custom headers
• Basic Firewalling: Restrict connections by host, drop connections on certain limits
• Automatic load balancing
• HTTP Cache headers
• In-memory backend response cache
• Multiple installation options (bin, docker, rpm, deb, brew)
• Cloud native
• Loved by orchestrators (Kubernetes, Mesos + Marathon, Nomad, Docker Swarm, and others)
• Secure:
  • Support for SSL
  • OAuth client grant
  • JSON Web Tokens (JWT) and JSON Object Signing and Encryption (JOSE)
  • HTTP Strict Transport Security (HSTS)
  • Clickjacking protection
  • HTTP Public Key Pinning (HPKP)
  • MIME-Sniffing prevention
  • Cross-site scripting (XSS) protection
  • Cross-origin resource sharing (CORS)
