• Native XMPP server. Full implementation of the XMPP (Extensible Messaging and Presence Protocol) version 1.0. Provides all core components for federation, messaging, and presence. The architecture complies with official RFCs to guarantee interoperability with other compatible clients and servers.
• Flexible authentication. Multiple configurable authentication methods, including internal database, LDAP, Active Directory, and custom providers. Supports anonymous authentication for specific cases and TLS certificate authentication for high security.
• Embedded database. Includes the HSQLDB embedded database for rapid deployments without external dependencies. This database operates in memory or on disk, suitable for test environments or small installations with minimal administration requirements.
• Communication encryption. Full TLS/SSL implementation for encrypting client-server and server-server connections. Supports self-signed certificates and those from certificate authorities. Granular configuration to require encryption on specific connections.
• Web administration. Browser-based administrative console with complete access to server configuration. Interface organized into sections for users, groups, chat rooms, components, and plugins. No additional software required on administration stations.
• Plugin system. Extensible architecture via plugins that add functionality to the core. The official repository includes plugins for monitoring, integration, bridges to other protocols, and advanced administrative tools. Plugins are installed from the administrative console.
• Audit logging. Configurable logging system with different detail levels for server events. Logs connections, authentications, system messages, and administrative activities. Logs can be redirected to external analysis systems.
• Multi-user chat rooms. Conference room service (MUC) with persistent moderation. Supports public and private rooms, history logging, participant roles, and access lists. Rooms can be configured as temporary or permanent.
• File transfer. Implementation of File Transfer according to XEP-0096 and XEP-0234. Allows direct transfers between clients or via the server acting as a proxy. Includes controls for maximum size and allowed file types.
• Directory service. User directory browseable from XMPP clients. Displays presence information and contact data. Integrates with external LDAP systems for automatic population of the corporate directory.
• Offline messaging. Storage of messages for disconnected users with automatic delivery upon reconnection. Configurable storage limits and retention times. History accessible from compatible clients.
• Resource monitoring. Integrated tools to monitor memory usage, active connections, and system load. Provides real-time and historical statistics. Exports data in formats for external monitoring tools.
• Horizontal clustering. Configuration of multiple instances in a cluster for high availability and scalability. Session and message sharing between nodes. Load balancing via external hardware or software.
• Gateway to other protocols. Connectors to external messaging systems via plugins. Availability of gateways for ICQ, AIM, MSN, Yahoo Messenger, and other legacy protocols. Bidirectional translation of messages and presence.
• Bandwidth control. Configurable bandwidth limitation per connection or globally. Traffic prioritization by type (messaging, files, presence). Policies to prevent abuse in environments with limited resources.

Development of Openfire began in 2001 under the name Jive Messenger, created by Jive Software. In 2004 it was renamed to Wildfire and later to Openfire. The Ignite Realtime community currently maintains and develops the project. The server is primarily developed in Java, using technologies such as Java Servlets for the administrative console and native socket implementation for the XMPP protocol. The codebase has evolved for over two decades, with contributions from developers in the Ignite Realtime community.
