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.
