Open Source Chat Projects
Chat software enables people to exchange messages in real time or asynchronously, whether in private conversations, group discussions, or online communities. It helps teams and individuals coordinate, share information, and stay connected across devices. Chat tools can also address needs such as privacy, self-hosting, communication across different networks, and preserving message histories for reference or recordkeeping.
Open source chat tools include messaging clients and servers, platform bridges, remote-access utilities with chat features, and tools for exporting or archiving conversations. When choosing one, consider its security and privacy model, supported platforms and integrations, license, maintenance activity, and the technical requirements for setup and operation. These tools are useful for individuals, communities, organizations, and developers who want greater control over how conversations are handled.
