HARP open source beta

An open-source HTTP proxy for your remote APIs, built for speed, reliability and observability.

Language

Python

License

LGPL-3.0

Version

v0.9.1

Install

pip install harp-proxy

HARP sits between your applications and the third-party APIs they depend on. It caches responses, retries transient failures, trips a circuit breaker when an upstream is failing, and records every call, so you can see exactly what left your infrastructure and what came back. Adoption is meant to be cheap: point your calls at the proxy and change nothing else in your code.

It ships an observation dashboard, standards-compliant HTTP caching, an audit trail and a rules engine. The open-source Community Edition is LGPL, alongside commercial editions. It is at 0.9 and under heavy active development, used in development and production, with some APIs still liable to change.
