Facts

Website: igniterealtime.org
Price: Free tier
Free trial: No
Administration: The project describes Openfire as easy to set up and administer.
Administration features: The 5.1.0 release added configurable incoming-connection rate limiting, DNS override management, failed server-to-server connection diagnostics, and a Docker healthcheck.
Client compatibility: The project says any application implementing XMPP can be used with Openfire.
Databases: The 5.1.0 release added MariaDB, Firebird, and CockroachDB to the supported database lineup, while noting that most plugins did not yet support them.
Downloads: The download page lists Windows installers, a ZIP archive, RPM and Debian packages, a Unix tarball, and a macOS DMG.
Extensibility: Plugins extend Openfire functionality and are installed by copying their JAR file into the installation's plugins directory.
Integrations: Documentation describes integration with LDAP user stores, custom databases, and external authentication, user, and group providers.
License: Openfire is licensed under the Open Source Apache License.
Runtime requirement: Openfire releases no longer include a Java Runtime Environment starting with version 4.7.0.
Security: The 5.1.0 release added SASL channel binding, which the release notes say ties authentication to the TLS connection and addresses a class of man-in-the-middle attacks.
Support: The support page directs users seeking professional support or services to a directory of professional partners and also links to community forums and group chat.
