About ZapClaw

In short: ZapClaw is a WhatsApp Business API gateway run by CHARLES BERTI TECNOLOGIA DA INFORMAÇÃO LTDA, a company in São Paulo, Brazil, founded by Charles Berti. It has been online since April 2026.

What ZapClaw is

ZapClaw connects your WhatsApp Business number to Meta's official Cloud API through Coexistence, so the number keeps working in the WhatsApp Business app on your phone. Messages your customers send arrive at your webhook, and your systems reply through a REST API.

ZapClaw is a Meta Tech Provider: you connect the number in Meta's own window, with no Meta app of your own and no App Review. See how it works, what you need to connect and the plans.

Who runs it

• Company: CHARLES BERTI TECNOLOGIA DA INFORMAÇÃO LTDA, a limited company registered in Brazil. ZapClaw is its brand.
• Company number: CNPJ 66.037.451/0001-01. The CNPJ is the number Brazil's federal tax authority gives every registered company.
• City: São Paulo, Brazil.
• Founder: Charles Berti, who leads the product (LinkedIn).
• Also from the same company: Monely, a personal finance app on WhatsApp that runs its own numbers on ZapClaw (how Monely uses it).
• Contact: the contact page or contato@zapclaw.app. We answer by email.

Since when

• April 2026: the first version of ZapClaw and of this site goes online.
• July 2026: Monely moves its WhatsApp numbers to ZapClaw.
• October 2026: the site and the dashboard speak Spanish too, next to English and Portuguese.

What ZapClaw is not

The name gets mixed up in search. ZapClaw lives at zapclaw.app, and its public repositories are under github.com/zapclaw. These are other things:

• Not ZapFlow. If a search for ZapClaw showed you ZapFlow, that is a different name. ZapClaw has no connection to any product called ZapFlow.
• Not zapclaw.net. zapclaw.net is a separate site in Portuguese, also called Zapclaw, that offers to build your own AI agent for WhatsApp. It is not ours, and we have no connection to it.
• Not github.com/mkulariya/zapclaw. That repository is an open-source project also named ZapClaw: its README describes an AI agent written in Rust, a clone of OpenClaw. It belongs to another developer and has no connection to us.
• Not Meta, and not WhatsApp. ZapClaw is run by an independent company that uses Meta's WhatsApp Business Platform as a Tech Provider. The official part is Meta's Cloud API.
• Not an unofficial library. ZapClaw does not run a WhatsApp Web session on a server: the number connects to Meta's Cloud API in Meta's own signup window. See how unofficial libraries compare with the official WhatsApp API.
• Not a game. ZapClaw is not related to any video game.

Where to find ZapClaw

• Website: zapclaw.app, in English, Portuguese and Spanish.
• Dashboard: app.zapclaw.app, where you connect a number, set your webhook and create API keys.
