  Stop wasting time on manual data entry. Fillr is an advanced form filler and test data generator built specifically for developers, QA engineers, and product teams. Whether you need to instantly bypass a tedious multi-step signup or generate thousands of rows of realistic mock data for stress testing, Fillr accelerates your workflow with powerful automation.
  
  🚀 Core Features
  
  ⚡ 1-Click Form Automation & Extraction: Easily scrape form structures directly from the page and save them to the cloud. Inject these saved configurations (Presets) instantly with a single click.
  
  🧠 Extensive Mock Data Library: Go beyond static "asdf" text. Fillr integrates a massive library of realistic data types (names, emails, addresses, credit cards, and niche technical fields like VINs or IBANs) to generate dynamic, accurate test data on the fly.
  
  📊 Bulk Data Generation (Scale & Export): Scale your single-form Presets into massive datasets. Generate and export thousands of realistic data rows in seconds for robust load testing, stress testing, or database seeding.
  
  🎯 Floating Action Bar UI: Access your tools without losing context. Fillr embeds a draggable, floating Action Bar directly onto the webpage for lightning-fast "Save," "Fill," and "Clear" commands.
  
  🌍 Real Localization (i18n): Generate geo-specific test data, including country-specific addresses, phone numbers, and names, to simplify internationalization testing directly in the browser.
  
  💻 Centralized Web Dashboard: Organize your Presets into custom categories, manage team billing, and drag-and-drop your configurations in our powerful web app. Everything syncs to your extension in real-time.

  Fillr is a form filler and test data manager for Chrome — for when it matters what goes into every field. Save any form as a preset with a rule per field, fill it from your own CSV or Excel rows, and manage all your test data in one place. Realistic generated data (110+ types, 60+ languages) is built in — but you decide where it goes.
  
  Anyone can spray random values into a page. Fillr is for when the data has to be right.
  
  🎯 EVERY FIELD, YOUR RULES
    ✓ Capture any form once and save it as a reusable preset
    ✓ Set a rule per field: Generate, Fixed value, Blank, Skip, or Dataset column
    ✓ Presets auto-match pages by URL pattern — the right preset surfaces the moment you land on the page (with a picker when several match)
    ✓ Preview the fill before you run it
    ✓ Unlimited presets, free
  
  📊 FILL FORMS FROM YOUR OWN DATA (Pro)
    ✓ Link a dataset to a preset, map columns to fields, and fill row by row — sequential with a "row 3 of 20" readout, or random
    ✓ Run 50 test cases through the same checkout without typing a single value
    ✓ Your edge cases, your real records, your regression rows — not random noise
  
  🗂️  A REAL TEST DATA MANAGER
    ✓ Import CSV, Excel or JSON — or generate sheets of realistic dummy data
    ✓ Edit rows in a spreadsheet grid, organize with tags
    ✓ Export any dataset to CSV, Excel or JSON
  
  ⚡ INSTANT FILL, WHEN YOU JUST NEED VALUES
    One click auto-fills every field with realistic fake data — names, emails, addresses, phones, dates and more. Zero setup, works on any
    site, one-click Clear when you're done.
  
  🌍 60+ LANGUAGES (Pro — English is free)
    Generate locale-accurate names, addresses and phone numbers in French, German, Japanese, Arabic and dozens more for international testing.
  
  🖱️  POINT-AND-CLICK, 100% NO-CODE
    A side panel plus a draggable floating bar on the page. Fill, clear, capture, switch presets — no scripts, no selectors, no JSON to edit.
  
  👥 WHO IT'S FOR
    QA testers, developers, product managers, support and ops teams, freelancers testing client sites — anyone whose forms need the right data,
    not just any data.
  
  💎 FREE VS PRO
    Free forever: unlimited presets, ALL data generators, English locale, 3 datasets of 50 rows — genuinely useful, no trial clock.
    Pro ($9.99/mo or $99/yr, 7-day free trial): fill forms from your own data, generate a dataset from any form, unlimited datasets, all 60+
    locales.
  
  Everything lives in the companion web dashboard at fillr.app — your presets and datasets follow you across devices.
  
  Stop typing test data by hand. Add Fillr to Chrome and take control of your next fill.
