What channels does Zavu support?

Zavu currently supports WhatsApp, SMS, voice calls, email, Telegram, Instagram, Messenger, Discord, and soon Slack and TikTok. Adding a new channel only requires a single API call, no code changes.

How is pricing structured?

Zavu offers a free plan ($0/mo) with limited credits, a Pro plan ($20/mo) with unlimited messaging and a $20 credit for SMS/voice/email, and custom Enterprise pricing. Pay only for messages sent; no markup on carrier or platform fees.

Can I use my own LLM for AI agents?

Yes. Zavu’s LLM proxy lets you bring your own key, or you can use included models like Qwen3, Kimi, Claude, GPT‑4o, etc., without extra markup.

How do I get real phone numbers?

Zavu provisions real phone numbers through its API. You can buy numbers in any supported country, then connect them to WhatsApp or any other channel with a single request.

About

Zavu unifies WhatsApp, SMS, email, voice, Telegram, Messenger and more under one API and billing. It lets you build AI agents that answer on every channel without vendor lock‑in. The platform handles number provisioning, compliance, routing and message templates, so you can focus on bot logic. With a single webhook and no markup, you pay only for what you send.

The case

Who it is for

Product and engineering teams building customer support or marketing automation who need a single, low‑cost API to reach users on WhatsApp, SMS, email, voice, Telegram and other channels.

What is broken today

Before Zavu, teams had to integrate separate vendor APIs for each channel—WhatsApp, SMS, email, voice, Telegram, Messenger—adding complex code, multiple billing statements, and vendor‑specific compliance. This fragmented approach raised costs, slowed feature rollouts, and made scaling difficult.

What it does about it

Zavu exposes one RESTful API that supports all channels. A single webhook handles inbound and outbound traffic, while the platform provisions real phone numbers, manages templates, and routes messages. It also offers AI‑powered agents that can answer customers on any channel, with built‑in memory and function calls.

Why not the obvious alternative

Unlike individual providers, Zavu bundles all channels into one bill with no markup and a single SDK. Its agent‑first model automatically sets up routing, compliance queues, and number provisioning, eliminating the need for separate vendor contracts. The free plan gives 2,000 messages on popular channels and 2,000 credits for SMS/voice, letting teams prototype without a card.

I’ve worked around messaging for years across multiple companies. Each growth phase turned into a new vendor, routing layer, and invoice we couldn’t explain. Zavu is the unified layer I wanted—one API, real numbers, and a single bill. If you’re looking at us, write to me.
