Testimonials
Finally, a devtool that actually gets the testing workflow. Saving different form presets for edge cases has cut my regression testing time in half.
The floating bar is a lifesaver. It’s so much faster than digging through extension popups every time I need to fill a signup form during local dev.
The bulk data exporter is the feature I didn't know I needed. Generating 500 rows of realistic test data as a CSV took me less than a minute.
I use this for every single product demo. Being able to populate a form with clean, professional-looking data in one click makes the whole presentation look way more polished.
Testing internationalization used to be such a chore. Now I just swap regions in the preset settings and I’ve got localized addresses and names ready to go.
No more typing 'asdf' into every field. The realistic data generator keeps my dev environments clean and actually helps catch layout issues early on.
Solid tool for bug reproduction. I just save the exact preset that caused the crash and send the data configuration over to the rest of the team.

A "Preset" is a saved configuration for a specific web form. After you map the data types you want for each field (e.g., field one gets a random "Email," field two gets a "UK Address"), you can save it as a "Preset" to instantly populate that form with one click anytime.
Fillr is designed for professionals who need to save time and improve accuracy. It's an essential tool for QA testers running scenarios, developers populating databases with mock data, and anyone who wants to automate repetitive data entry.
Yes. Fillr is built for global use and supports data localization for over 60 countries. You can instantly fill forms with culturally and linguistically appropriate names, addresses, phone numbers, and more.
Yes. Any "Fillr" you create can be used to generate structured data on demand. You can instantly download an Excel or JSON file containing any amount of realistic data based on your saved configuration.
Absolutely. Fillr operates locally in your browser. We do not see, log, or store any of the data you input into forms. Your saved "Fillrs" are securely stored in your account for your access only.
