Comparison
wavalid vs. WA-Filter
How wavalid compares to WA-Filter's WhatsApp Number Checker for validating numbers before you send.
Best fit if you don't want checks tied to your WhatsApp account
WA-Filter simulates real WhatsApp usage through your own account to reduce ban risk from the check itself, but that still means running checks against your live account. wavalid checks numbers through its own systems entirely, so your account is never involved.

wavalid, for one credit price, bulk CSV, an API, and an MCP server.
Best for a free in-browser filter

Best developer fit
wavalid's REST API and MCP server plug straight into AI agents and pipelines.
Evaluation criteria
Bulk support, pricing clarity, WhatsApp focus, and account safety.
Where WA-Filter falls short
Runs against your own WhatsApp Web session
It requires logging into WhatsApp Web and simulates real usage through your account to run checks, which its own site addresses as a ban-risk concern.
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.
Chrome-only, no hosted dashboard
Checks and history live inside the extension, with no hosted dashboard to revisit results from another device.
