Free WhatsApp developer tools
Eight free tools for WhatsApp developers: check whether a number is registered, build click-to-chat links and the QR codes that carry them, preview how a message will render, escape a JSON body, convert phone numbers to JIDs, read a group invite link before joining, and inspect a webhook delivery. Everything except the live number check runs in your browser; nothing is uploaded.
