Coding Classroom VS Fillr.app

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.

Questions & Answers

As answered by people managing Coding Classroom and Fillr.app.

What makes your product unique?

Fillr.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 — plus a built-in Datasets module to build, generate, and export test data. A form-filler and test-data manager in one, no code.

Why should a person choose your product over its competitors?

Fillr.app's answer:

Fake Filler only sprays random data; Mockaroo generates data but can't fill forms. Fillr does both — and lets you fill with your own data, with reusable presets, per-field control, and 60+ locales. No scripts.

How would you describe the primary audience of your product?

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.

Which are the primary technologies used for building your product?

Fillr.app's answer:

Next.js 15, React 19, and TypeScript dashboard; a Manifest V3 Chrome extension built with Vite and supabase for backend
