Envoy Proxy

Envoy Proxy belongs in the database because it is one of the most foundational traffic infrastructure projects in modern cloud-native systems. The official site positions it as an open-source edge and service proxy for cloud-native applications, with strong support for HTTP/2, gRPC, advanced load balancing, dynamic configuration, and observability. In practice, Envoy often shows up beneath higher-level tools rather than as the first product a buyer compares, but it is still important enough to deserve its own entry because many teams evaluate whether they want to adopt Envoy directly or through platforms built on top of it.

For directory quality, Envoy is also a useful example of infrastructure that is clearly product-grade despite not operating like a SaaS. There is no native pricing page because the project itself is open source. Instead, teams either run Envoy directly, embed it in a platform, or purchase commercial products and managed services built around it. That means the database should frame Envoy as a lower-level universal data plane and proxy building block rather than a turnkey platform purchase.
