Questions & Answers

As answered by people managing FreeFormatter and DevelopK.kr.

What makes your product unique?

DevelopK.kr's answer:

developk.kr offers 61 free developer tools you can use instantly in your browser, no sign-up required. All processing happens client-side, so nothing you type is sent to a server. The tools are organized into 4 categories (network, security, coding, text), and 15 written guides are included to help you use them.

How would you describe the primary audience of your product?

DevelopK.kr's answer:

Developers and engineers who run into small, repetitive tasks during their workday, things like formatting JSON, generating a hash, checking DNS records, or converting units, and want a fast browser-based tool instead of hunting through ad-heavy sites. It's also popular with solo developers and freelancers who value the no-signup, privacy-friendly approach.

What's the story behind your product?

DevelopK.kr's answer:

developk.kr started as a single indie side project: small dev tools built one at a time to solve the maker's own recurring annoyances, like reformatting a messy JSON blob or looking up DNS records, on sites full of ads and forced sign-ups. Each tool was added because it was genuinely needed for real work, and the collection has since grown to 61 tools across 4 categories, plus 15 written guides.

Why should a person choose your product over its competitors?

DevelopK.kr's answer:

Most online tool sites require sign-up, run ads, or collect your email before you can use them. developk.kr skips all of that. Because everything runs client-side in your browser, it's also safe to paste sensitive values like API responses or auth tokens without worrying about where that data goes.

Which are the primary technologies used for building your product?

DevelopK.kr's answer:

developk.kr is built as static HTML/CSS/JavaScript (no backend framework), with a shared common.js handling the header, footer, and ad mounting across all tool pages. It's hosted and served through Cloudflare (Pages, with redirects handled via a Cloudflare Pages Function), and uses GA4 for analytics.
