Open Source Chatbot Projects
Chatbots are software systems that communicate with people through text or voice, answering questions, guiding tasks, and automating conversations. They can follow predefined rules, use language models to generate responses, or combine both approaches. Chatbots help make support and information available at any time, reduce repetitive work, and provide conversational interfaces for services and data.
Open source tools in this area include visual bot builders, programmable frameworks, self-hosted chat interfaces, messaging integrations, and systems that connect responses to documents or external tools. When choosing one, consider its license, maintenance activity, deployment requirements, supported channels, privacy controls, and integration options. These tools can be useful to developers, organizations, and individuals building customer support, internal assistants, or conversational features for applications.
