- This extension is awesome! It saves me tons of time when testing forms — just one click and everything’s filled with realistic fake data. The field detection works really well, and I like that you can tweak the settings and create your own templates. The UI looks great and it runs super smoothly. Also, big plus that all the data is generated locally — no privacy worries. Works perfectly with React and other modern apps. Honestly, if you’re a dev or QA tester, you need this.

- FakerFill saved me tons of time. As a QA Engineer, I deal with forms every day, and manually filling them was always the most boring part of my job. With FakerFill, that's gone — I can fill entire forms in seconds. The templates feature is my favorite — it lets me pick exactly which fields to fill and reuse the setup anytime. Simple, smart, and incredibly useful.
