Promxy
An aggregating proxy that provides a single API endpoint and high availability for multiple Prometheus shards.
What is Promxy?
Promxy is an aggregating proxy for Prometheus that makes multiple shards appear as a single API endpoint. It solves the problem of operating Prometheus at scale by providing high availability through data merging and simplifying query federation across hosts. It requires no changes to existing Prometheus infrastructure.
DevOps engineers, SREs, and platform teams running multi-host Prometheus deployments who need simplified management, high availability, and unified querying.
Developers choose Promxy because it delivers a seamless HA solution without sidecars or infrastructure modifications, offers a single query endpoint for Grafana, and maintains performance parity with downstream Prometheus servers.
