Bifrost

A low latency and high throughput API Gateway library written in Go.

Goal

1. Low latency and high throughput.
2. Allows writing middlewares in native Go.
3. Easy to integrate with existing Go services.
4. Built as an SDK/library instead of an artifact.

Features

1. Support for writing middleware in Go.
2. Low latency and high throughput (powered by the Hertz framework).
3. Millisecond-level hot reloads for route updates without interrupting requests.
4. Built-in Prometheus monitoring.
5. Built-in OpenTelemetry tracing.
6. Supports HTTP1.1/HTTP2/H2C/Webosocket/GRPC protocols.
