Tigase is an open-source, Java-based XMPP server for real-time messaging, presence, and IoT. See features, licensing, and pricing options.
Tigase is a high-performance XMPP (Jabber) server used to build real-time messaging, presence, and communication systems. Its origins go back to an open-source project started by developer Artur Hefczyc in October 2004, and the commercial company behind it, Tigase, Inc., was formally founded in 2010 and is headquartered in San Francisco, California.
Tigase XMPP Server is written in Java and implements the open XMPP protocol standard, the same decentralized, federated messaging protocol historically used by Jabber-based chat systems. Tigase has also been an active sponsor of the XMPP Standards Foundation, contributing to the evolution of the protocol itself alongside its server products.
The software is dual-licensed, offered as fully free and open source under the AGPLv3 license, with an optional commercial license available for organizations that need to build closed-source or proprietary products without AGPLv3's copyleft requirements.
Tigase supports horizontal clustering, allowing deployments to scale across multiple nodes for high availability and larger user bases, along with a pluggable component architecture that lets administrators extend or customize server behavior without modifying the core codebase.
The server implements key XMPP extensions such as multi-user chat (MUC) for group conversations and PubSub for publish-subscribe messaging patterns, and it exposes REST and WebSocket APIs so modern web and mobile clients can integrate without needing native XMPP client libraries.
Tigase also provides its own client libraries for iOS, Android, and desktop platforms, along with support for push notifications and mobile-optimized connection handling, and has positioned its technology for IoT messaging use cases in addition to traditional chat applications.
The open-source edition of Tigase XMPP Server is free to use under the AGPLv3 license, with full access to the source code for self-hosted deployment at any scale.
For organizations that cannot comply with AGPLv3's copyleft terms, Tigase offers a commercial license along with separate technical support plans; pricing for both is not publicly published and is provided on a custom basis by contacting Tigase's sales team, with tiers historically differentiated by deployment size, from smaller systems up to large-scale deployments with 100,000 or more users.
