Fill forms with coherent fake data for testing — names, emails, dates, bios, and filler text. No AI, no network calls.
Gobbledygook fills web forms with realistic, coherent fake data — instantly. Built for QA testers, developers, designers, and anyone who's tired of typing "asdf" into form fields.
What it does:
• Fill a single focused field or an entire form with one click or keyboard shortcut
• Generates a consistent persona per form: the name, email, username, and bio all match
• Recognizes 60+ field types including names, email, phone, address, date of birth, credit card (test numbers only), social media URLs, pronouns, and more
• Smart SELECT handling — picks contextually appropriate options, not just random ones
• Works with modern SPAs and React apps, not just plain HTML forms
• Scout mode highlights every detected field on the page so you can see what the extension recognizes
How to use:
• Click the toolbar icon and choose "Fill this field" or "Fill entire form"
• Right-click any input for context menu options
• Keyboard shortcuts: Alt+Shift+J (field), Alt+Shift+K (form), Alt+Shift+L (scout)
Privacy first:
• Zero network calls — all data is generated locally from bundled word lists
• No analytics, no tracking, no remote servers
• No AI — just deterministic random generation
• All data stays in your browser; nothing is stored except your settings
Configurable:
• Set your preferred email domain (maildrop.cc for disposable inboxes, or your own)
• Adjust birth year range, checkbox probability
• Supply custom filler text to replace Lorem Ipsum
Gobbledygook respects your time. It fills what it recognizes, skips what it shouldn't (search bars, people pickers, schedule widgets), and tells you clearly what it doesn't understand. No bloat, no subscription, no nonsense.
