As answered by people managing Clockify and DevelopK.kr.
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.
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.
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.
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.
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.
