XMPPl is a proposed extension to the Extensible Messaging and Presence Protocol (XMPP) intended to enable lightweight messaging with reduced overhead for mobile and low-bandwidth environments. It seeks to preserve interoperability with standard XMPP while offering optional modules that optimize delivery, presence, and security for constrained clients.
Its architecture centers on a core XMPPl module that defines a compact set of message stanzas and
Security and privacy in XMPPl are modular; end-to-end encryption is supported through established XMPP encryption methods,
Development and adoption: XMPPl remains experimental and has not been standardized by the XMPP Standards Foundation.
