Skipper

What Skipper is

Skipper is a free, open-source HTTP router and reverse proxy for composing services, including Kubernetes Ingress deployments. It identifies routes using request details such as path, method, host, and headers, then applies independently configured filters that can modify requests and responses. Route definitions can come from sources such as etcd, Kubernetes Ingress, static files, route strings, or custom configuration sources, and routing rules can be updated without downtime. Skipper can stream incoming requests and backend responses simultaneously, or act as a final endpoint for uses such as serving static files or diagnostic mock responses. It can run as a Kubernetes Ingress controller, with features including rate limiters, circuit breakers, blue-green deployments, and shadow traffic. The project documents HTTP/1.1, H2C, and HTTP/2 support, along with TLS termination, response caching, and WebSockets. Authentication proxy options include Basic authentication, OAuth2, and OpenID Connect, with audit logging. Skipper is self-hosted and available for Linux, macOS, and Windows; building and running it requires the latest Go version.
