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)
