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.
Vapi
Vapi is a voice-call platform available on the web and iOS. It supports inbound and outbound calls, human handoff, concurrent calls, and custom phone numbers. The usage-based No Success Package is listed at free and includes $5 in starter credits, one Vapi phone number, four concurrent calls, and full platform access. Core costs $29 a month, billed monthly, and includes five phone numbers, 10 concurrent calls, 30 days of raw data retention, and email support. Pro costs $999 a month, billed monthly, and includes 10 phone numbers, 30 concurrent calls, 180 days of raw data retention, RBAC, ZDR, and a 99% uptime SLA. Premier uses custom pricing; its listed options include custom phone-number counts and custom RBAC, ZDR, and SSO, with dedicated SIP available. The service listing says there is no free plan, although the No Success Package is presented at no cost with starter credits. Plan allowances vary, so the listed overall concurrent-call figure of 10 is not the allowance for every package.
