Harp Proxy – open-source API Proxy for reliability and observability

In plain words

Harp Proxy is an open-source API proxy designed for developers and teams who need to improve reliability and observability of their APIs. It intercepts and manages API traffic to provide visibility into request patterns and system behavior. The tool launched in September 2024 and is built as a lightweight alternative to heavier API gateway solutions, making it suitable for teams managing microservices architectures or complex API ecosystems.
