Finagle Status This project is used in production at Twitter (and many other organizations), and is being actively developed and maintained. Releases Releases are done on an approximately monthly schedule. While semver is not followed, the changelogs are detailed and include sections on public API breaks and changes in runtime behavior. Getting involved Website: https://twitter.github.io/finagle/ Source: https://github.com/twitter/finagle/ Mailing List: finaglers@googlegroups.com Chat: https://gitter.im/twitter/finagle Blog: https://finagle.github.io/blog/ Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers. Finagle implements uniform client and server APIs for several protocols, and is designed for high performance and concurrency.
