About Plivo
Plivo is a communications API platform whose homepage now leads with voice AI agents. You can build agents two ways: with code — SDKs for Python, Node, and Go, a REST API, and a CLI, with documented paths for bringing LiveKit or Pipecat agents onto Plivo — or with a no-code Agent Studio where you describe the agent in plain English and deploy from templates. Under both sits Plivo's telephony layer: self-serve SIP trunking, bidirectional audio streaming with noise cancellation, and phone numbers across 150+ countries. Alongside voice, the platform covers SMS, WhatsApp, and chat. The site lists example use cases such as sales lead qualification, order tracking, payment collection, feedback surveys, and identity verification, and includes a recorded demo call in which an agent reschedules a dental appointment and texts a confirmation. Stated figures: under 500 ms voice latency, 99.99% platform uptime, and 50+ languages supported. Customer logos displayed on the homepage include Meta, Uber, Discord, GoDaddy, and DocuSign.
What it does

- Two build paths — programmable (SDKs, REST API, CLI) or a no-code Agent Studio with prompt-based setup, templates, and instant preview
- Framework integrations — dedicated pages for LiveKit (SIP trunking to give agents real phone numbers) and Pipecat (streaming live call audio into pipelines)
- Telephony — self-serve inbound and outbound SIP trunks, bidirectional audio streaming, and phone numbers in 150+ countries
- Channels — voice, SMS, WhatsApp, and chat
- Developer tooling — a CLI (
brew install plivo/tap/plivo) that can test WebSocket audio streams and diagnose failed calls from the terminal
