Developer & QA Tools

Request a URL from Globalping probes in the regions or countries you choose and compare status codes and DNS, connect, TLS and first-byte times by location.

Check whether up to five domain names are taken, from the registry's RDAP answer and public DNS together; "likely available" only when both agree.

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.

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.

Format, beautify and validate JSON instantly in your browser with custom indentation.

Generate a throwaway email address and read what arrives, on the same page. The address is released when you stop using it.

Generate UUID v4 (random) and v7 (time-ordered) identifiers in bulk, and validate existing ones.

Convert Word documents (.docx) to PDF in your browser — a searchable text PDF with embedded fonts, or a layout copy of the pages as your browser renders them.

Generate IBAN-like test numbers with valid check digits for SA, JO, AE, GB, DE and more — for validation testing only.

View, edit or remove the hidden properties of a Word document (.docx): author, company, last modified by, revision, editing time, custom properties and comment authors — in your browser.

Send a DNS query over HTTPS to Cloudflare, Google or eight public resolvers and inspect the response code, flags, records, TTLs and timing.

Perform full boundary value analysis (2-value and 3-value BVA) with equivalence classes and expected results.

Find duplicate and near-duplicate pages in a PDF: which pages repeat, grouped, and how each match was made. In your browser; the file is not changed.

Read QR codes from a photo, screenshot or scan in your browser: links, Wi-Fi details, contacts and text, several codes per image. Nothing is uploaded.

Analyze a browser HAR file: failed and slow requests, redirects, large and repeated requests — and find the cookies and tokens it contains before you share it.

Check HTML for common accessibility problems — missing alt text, unlabeled fields, nameless buttons and links, ARIA errors, headings, contrast — mapped to WCAG 2.2.

Build a requirements traceability matrix from your own requirements and test cases: coverage, requirements without tests, orphan tests and broken links.

Plan future-date and time-zone tests: for an expiry, deadline, renewal, age or schedule rule, get the clock moments to test and the expected result at each.

Generate a test plan from a template: pick website, mobile app, API, agile sprint or release, fill in what you know and get a complete Markdown plan to edit.

Estimate test effort with the three-point formula: list tasks with optimistic, most likely and pessimistic values and get PERT estimates, ranges and team days.
