10 Insanely Useful Fake Data & Mockup Generators Every Developer Needs in 2025 (All Free, No Signup)
As developers, we constantly need dummy data, mockups, or quick prototypes — whether it's for testing APIs, building demos, seeding databases, or just pranking a teammate.
The problem? Most fake generators are either:
- Covered in ads
- Require sign-up
- Watermark outputs
- Upload your data (privacy nightmare)
I got tired of that noise, so I built a completely free, no-BS collection that runs 100% in the browser.
