Rapida AI is an open-source platform for building and operating voice AI agents across phone, web, WhatsApp and SIP. It supports speech processing with voice activity detection and noise cancellation, knowledge retrieval, language-model routing and live call transfer. Teams can bring their own speech-to-text, text-to-speech and language-model providers or route between them without rewriting application logic. Listed integrations include Twilio, Vonage, Exotel, Asterisk, OpenAI, Anthropic, Google Gemini, Deepgram, ElevenLabs, Azure and AWS. Agents can call HTTP endpoints during conversations and sync data from Notion, GitHub, HubSpot and Jira. Rapida provides session traces, transcripts, call monitoring, handoff visibility, request and webhook logs, and debugging context. It offers managed cloud or self-hosted deployment. The maker says self-hosting keeps audio, transcripts and customer data on the user's infrastructure; setup requires Docker and at least 4 GB RAM for Voice Only, or 8–16 GB with the knowledge base. Launch is free. Scale costs $500 a month, Grow costs $2,000 a month, and Enterprise pricing is custom.
