Yes, absolutely! HARP is built as a lightweight service that can be scaled horizontally and/or vertically. We work with our enterprise customers to fine tune their hosting environment to suit their API traffic.

The Community Edition is Open-Source. The Professional and Enterprise editions are based on the open-source core, but comes with enhanced security and scalability related features, along with enterprise-grade support.

While the open-source Community Edition is based on a fully custom proxy, the Professional and Enterprise editions are leveraging Envoy Proxy as its network traffic management proxy, a very stable and externally audited proxy trusted by big technical companies like Google, Lyft, Uber and much more. All critical traffic will go through the battle-tested proxy.

No, HARP is installed on premise in your own infrastructure. Your data never leaves your datacenter or cloud environment, and is kept at the nearest distance of your applications.
