Tyrus review
A self-hosted Jakarta WebSocket implementation with client, server and container options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tyrus is an open-source Java implementation of the Jakarta WebSocket API, formerly JSR 356, distributed as Maven modules for Java applications. It is aimed at teams building bidirectional WebSocket applications in Java, particularly those implementing Jakarta WebSocket endpoints. Its scope includes both client and server APIs, with support for Jakarta WebSocket versions 1.1, 2.0, 2.1 and 2.2. As a library rather than a hosted service, it fits projects that can deploy and operate their own application stack; teams seeking a hosted WebSocket service should look elsewhere.
The implementation offers several ways to run and integrate WebSocket functionality. Teams can use standalone server mode, integrate with servlet containers, or use Grizzly client and server containers. Endpoint development can be annotated or programmatic, with message handlers, encoders and decoders for processing messages. WebSocket extensions and frame handling are also part of the feature set. These options make Tyrus suitable for applications that need control over endpoint construction and container choice, though the range of APIs and deployment paths may be more than a narrowly scoped client needs.
Tyrus also includes JMX monitoring and connection limits, and its listed integrations include Grizzly, GlassFish CDI, GlassFish EJB and servlet containers. It is self-hosted and open source, with documentation and community support channels. That combination suits teams comfortable managing a Java library within their own deployment and selecting the container integration that matches their application. It is a less natural fit for organizations that want a managed service, a non-Java SDK, or a support model centered on channels beyond documentation and community.
