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...

As answered by people managing Fillr.app and Repothread.
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.
Repothread's answer:
What makes Repothread unique is its multilingual approach. Instead of generating repository reports in just one language, Repothread can present codebase analysis in 10 different languages. This makes open-source projects more accessible to global developers, learners, and teams who want to understand a repository in their native language rather than relying only on English technical documentation.
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.
Repothread's answer:
I’d choose Repothread over other similar tools mainly because of the language support. A lot of repository analysis tools are useful, but most of them are still very English-centric. Repothread is more practical for people who want to understand a repo in their own language, especially when exploring unfamiliar projects. If someone learns faster or feels more comfortable reading technical explanations in their native language, that alone can make a big difference.
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.
Repothread's answer:
Developers, learners, and global teams exploring unfamiliar repositories
Repothread's answer:
Open-source repositories are valuable, but they are often hard to understand quickly, especially for people outside the project or outside the English-speaking developer community. The product focuses on making repositories easier to explore by turning them into structured, readable reports and making that experience available in multiple languages.
Fillr.app's answer
Next.js 15, React 19, and TypeScript dashboard; a Manifest V3 Chrome extension built with Vite and supabase for backend
Repothread's answer:
AI-driven code analysis, GitHub repository parsing, and multilingual content generation
Repothread's answer:
No major customers have been publicly highlighted yet, but the product seems most relevant for developers, open-source users, students, and global technical teams who need to understand repositories faster.
