Zavu

Agentic Communication Infrastructure for Modern Development

Zavu is a unified messaging and communication platform designed for developers and AI agents building customer-facing applications. It consolidates WhatsApp, SMS, voice, email, Telegram, Facebook Messenger, and Instagram into a single API, eliminating the complexity of managing multiple vendors, integrations, and invoices.

Built for AI Agents and Developers

Zavu is agent-first: your coding assistant can set up senders, buy phone numbers, connect channels, and deploy functions using built-in skills for Claude Code, Cursor, Codex, and 40+ other agents. The platform provides CLI commands, an MCP server, and dashboard automation that let both humans and AI agents provision infrastructure programmatically. Deploy AI agents that answer customers across all channels—using your documents, your tools, and your business logic—with deterministic workflows or non-deterministic LLM-driven conversations.

Key Features and Capabilities

Who It's For

Zavu serves development teams, SaaS companies, e-commerce platforms, agencies managing multiple clients, and any business building customer communication into their product. It's particularly valuable for teams deploying AI agents that need to reach customers wherever they are, and for developers tired of juggling multiple messaging vendors.
