Vocode is an open-source, modular framework (MIT-licensed) for building conversational voice AI agents. It provides abstractions for streaming LLM conversations, voice synthesis, and telephony, and can deploy agents to inbound and outbound phone calls, Zoom meetings, and other audio channels. A hosted cloud API was also offered for enterprise-grade phone call management. As of 2026, active development has largely stalled with minimal recent commits and unanswered issues. Key features: - Open-source Python library with modular architecture (Vocode Core) - Real-time streaming conversations with LLMs over voice - Deployment targets: phone calls, Zoom, and other audio channels - Python and Node.js SDKs - Hosted cloud API option for enterprise phone call management - Customizable voices and multilingual support
Open-source core is free. Hosted API pricing not publicly listed. Project raised $4M (YC); development activity has significantly declined by 2026.
