Armeria is an open-source asynchronous RPC/API client/server library built on top of Java 8, Netty 4.1, HTTP/2, and Thrift. Its primary goal is to help engineers build high-performance asynchronous Thrift microservices that use HTTP/2 as a session layer protocol, although it is designed to be protocol-agnostic and highly extensible (for example, you can serve a directory of static files via HTTP/2 and run Java EE web applications).

It is open-sourced and licensed under Apache License 2.0 by LINE Corporation, who uses it in production.
