Web Utilities
The small jobs around links, email and endpoints that come up every week: a short link that will still work next quarter, a QR code for a URL or a Wi-Fi network, a correctly encoded query string, the real path an email took through mail servers, the methods an endpoint accepts, whether a webhook or WebSocket endpoint you run is reachable and answering, and whether an IBAN someone sent you is well formed before you pay it.
The browser-side utilities — QR codes, query strings, email headers, IBAN checks, feature detection — never send your data anywhere. The connectivity checks send a small, fixed request from the Mutqan server to the endpoint you name and show you the answer; they are built for testing your own services and are rate-limited accordingly.

See where a short link really leads without opening it: every redirect with its status code and the final address, followed by the Mutqan server.
Web Utilities
Make a QR code for a web address in your browser: pick the error-correction level and colours, check the contrast, and download SVG or PNG.
Web Utilities
Make a QR code that joins a Wi-Fi network when scanned — name, security type and password, built in your browser. The password is readable in the code.
Web Utilities
See which web APIs, CSS features, media formats, storage and permission states this browser supports, tested by feature detection in the browser itself.
Web Utilities
Read a message's raw headers in your browser: the Received route, SPF, DKIM and DMARC results, sender alignment, origin address and warning signs.
Web Utilities
Pre-check a sending domain's DNS before you send: MX, SPF, DMARC and its reports, MTA-STS, TLS-RPT and reverse DNS of its mail hosts, as a checklist.
Web Utilities
Send empty GET, HEAD, OPTIONS, POST, PUT, PATCH or DELETE requests to a URL and see which methods it answers, with its Allow and CORS headers.
Web Utilities
Check that a webhook URL accepts a test POST: status, response time, HTTPS, redirects and headers, using one fixed test payload and one OPTIONS request.
Web Utilities
Turn a raw HTTP request, DevTools headers or a fetch() call into a curl command for Bash, PowerShell or cmd.exe, quoted safely for that shell.
Web Utilities
Check an IBAN in your browser: country, length and format from the SWIFT IBAN Registry, the MOD-97 checksum, and the bank and branch codes it contains.
