Comparison
wavalid vs. Infwiz
How wavalid compares to Infwiz's WA Checker for validating WhatsApp numbers before you send.
Best fit for teams that need automation, not a WhatsApp Web login
Infwiz's WA Checker works from inside WhatsApp Web after you scan a QR code to log in. wavalid checks numbers through its own systems, so no WhatsApp Web session is required, and it adds a REST API and MCP server.

Evaluation criteria
Bulk support, pricing clarity, WhatsApp focus, and account safety.
Where Infwiz falls short
Requires scanning into your own WhatsApp Web session
The tool works by logging into web.whatsapp.com first, so checks run through your own account rather than a separate backend.
No REST API or MCP server
It's a browser extension only, so there's no way to call it from a backend job, CRM automation, or AI agent.
Free tier is limited, paid upgrade required for more
Basic functionality is free, with more features gated behind a paid upgrade.
