In their own words
Rapida AI
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.
Tone
Tone is an open-source voice AI platform for building, deploying, and self-hosting voice agents. Agents can handle inbound or outbound calls, web widgets, or chat, combining prompts, tools, workflows, configurable models, voices, and speech-to-text providers. Its knowledge base accepts PDFs, scraped documents, Notion, and Confluence content, with chunking, embeddings, retrieval, re-ranking, citations, and custom vocabulary. A visual workflow builder supports branching, loops, human handoff, TypeScript hooks, and triggers from Zapier, REST API, or HighLevel. The test center runs simulated calls with personas, accents, and edge cases, supports parallel regression runs, and replays production calls. Observability includes interruption rate, latency, sentiment, gibberish detection, recordings, dashboards, and real-time alerts. Tone offers a TypeScript-first SDK, CLI, hosted API, and self-hosting through Docker Compose or a Kubernetes Helm chart. The Self-host plan is free. Cloud costs $0.09 per minute and includes $10 free credit with no card required; Enterprise pricing is custom.
