Test Data Management
Fillr is a form filler and test data manager for Chrome โ 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 โ but you decide where it goes.
Anyone can spray random values into a page. Fillr is for when the data has to be right.
๏ฟฝ EVERY FIELD, YOUR RULES โ Capture any form once and save it as a reusable preset โ Set a rule per field: Generate, Fixed value, Blank, Skip, or Dataset column โ Presets auto-match pages by URL pattern โ the right preset surfaces the moment you land on the page (with a picker when several match) โ Preview the fill before you run it โ Unlimited presets, free
๏ฟฝ FILL FORMS FROM YOUR OWN DATA (Pro) โ Link a dataset to a preset, map columns to fields, and fill row by row โ sequential with a "row 3 of 20" readout, or random โ Run 50 test cases through the same checkout without typing a single value โ Your edge cases, your real records, your regression rows โ not random noise
๏ฟฝ๏ธ A REAL TEST DATA MANAGER โ Import CSV, Excel or JSON โ or generate sheets of realistic dummy data โ Edit rows in a spreadsheet grid, organize with tags โ Export any dataset to CSV, Excel or JSON
โก INSTANT FILL, WHEN YOU JUST NEED VALUES One click auto-fills every field with realistic fake data โ names, emails, addresses, phones, dates and more. Zero setup, works on any site, one-click Clear when you're done.
๏ฟฝ 60+ LANGUAGES (Pro โ English is free) Generate locale-accurate names, addresses and phone numbers in French, German, Japanese, Arabic and dozens more for international testing.
๏ฟฝ๏ธ POINT-AND-CLICK, 100% NO-CODE A side panel plus a draggable floating bar on the page. Fill, clear, capture, switch presets โ no scripts, no selectors, no JSON to edit.
CodeLighthouse Fillr.appFillr.app's answer:
It leads with control, not random fill. Capture any web form as a reusable preset, set per-field rules (generated, fixed, your own data, or skip), and refill in one click โ plus a built-in Datasets module to build, generate, and export test data. A form-filler and test-data manager in one, no code.
Fillr.app's answer:
Fake Filler only sprays random data; Mockaroo generates data but can't fill forms. Fillr does both โ and lets you fill with your own data, with reusable presets, per-field control, and 60+ locales. No scripts.
Fillr.app's answer:
QA engineers and developers who repeatedly test web forms and need realistic, controllable test data. Demo and sales engineers are a natural secondary audience.
