Fillr

Saves web forms as presets and refills them in one click with generated realistic data or CSV rows

The product is a Chrome extension that saves any web form as a preset and refills it in one click with realistic generated data or rows from a CSV, solving repetitive manual entry, unrealistic autofill, and maintaining faker scripts for testing. It is for developers and QA roles in B2B teams who need to fill forms repeatedly during testing. It is delivered as a Chrome extension with a side panel, floating bar and dashboard that stores presets, applies per-field rules, and keeps data in the browser.
