The challenge
Developers waste time juggling dozens of scattered online tools that are slow, cluttered with ads, or quietly send your data to a server. We wanted to build one fast, beautiful, privacy-first toolkit that does it all in the browser — and ship it as a Progragon product.
What we built
- Designed and built 30+ tools across Text & String, Encoding & Security, Numbers & Time and Media & Files.
- Made every tool 100% client-side, so data never leaves the browser — private and instant.
- Crafted a clean, dark-mode-first interface that developers actually enjoy using.
- Kept it completely free with no signup, so anyone can use it in seconds.
