Founder Q&A
In the founder's words
Harun R Rayhan, Founder
Why did you build it?
I kept pasting data into random ad heavy sites to format JSON or decode tokens, so I built a clean, private set of tools that run fully in the browser.
Who is it for, and what problem does it solve for them?
Developers who need quick formatting, encoding and debugging tools without sending sensitive data to a server or creating an account.
What was the hardest moment so far, and what did you do?
Keeping every tool fast and fully client side; I rewrote several tools to avoid any server processing.
How did you get your first users or customers?
Search traffic and sharing in developer communities.
One piece of advice for other founders?
Ship small, useful things and listen to the people who actually use them.
