In their own words
LiveKit Agents
LiveKit Agents is an open source framework and cloud platform for building voice, video, and physical AI agents. Python or Node.js programs can join LiveKit rooms as realtime participants, and deployments can run on LiveKit Cloud or a developer-chosen environment. Agents can process realtime voice, video, and text input and produce output in any modality. The framework supports LLM tool use, frontend RPC calls, multi-agent handoffs, and connections to phone systems through native SIP. LiveKit Inference provides models from providers including OpenAI, Google, AssemblyAI, Deepgram, Cartesia, and ElevenLabs; open source plugins connect to other providers. LiveKit Cloud includes agent insights such as session replay, transcripts, trace spans, logs, and reports. The free Build plan includes 1,000 agent session minutes, five concurrent sessions, and one deployment. Ship starts at $50 a month and includes 5,000 minutes, then $0.01. LiveKit says prompts, audio, and completions handled by LiveKit Inference and its model providers are not logged or retained. It lists SOC 2 Type II, GDPR, HIPAA, CCPA / CPRA, and the EU–US Data Privacy Framework; PCI DSS and ISO 27001 are in progress.
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.
