As answered by people managing CodePen and FreeTextUtils.
FreeTextUtils's answer:
Built out of frustration with online text tools that either required signup, uploaded data to unknown servers, or bombarded users with ads. The goal was a single, clean, private workspace where all common text operations live under one roof — no bouncing between five different sites to get work done.
FreeTextUtils's answer:
Writers, SEO professionals, students, and developers who need quick text manipulation (word counting, regex, case conversion, slug generation) without the overhead of account creation or data privacy concerns.
FreeTextUtils's answer:
The only free text toolkit that combines 30 tools with reading time estimation built directly into the word counter, all running entirely in your browser with zero server uploads. Dark and high-contrast themes ship as a first-class feature for accessibility, not an afterthought.
FreeTextUtils's answer:
No signup, no ads interrupting your workflow, and no data ever leaves your device. Most competitors either send your text to a server, limit features behind paywalls, or require account creation. FreeTextUtils is genuinely free, genuinely private, and works offline.
FreeTextUtils's answer:
Vanilla HTML, CSS, and JavaScript — no frameworks, no dependencies. All processing runs client-side via native browser APIs. Static hosting ensures fast load times and zero server costs. JSON config files drive the tool catalog and guide registry.
FreeTextUtils's answer:
FreeTextUtils is a free public tool with no user tracking. It's used by freelance writers, SEO consultants, university students, and web developers worldwide who find it through organic search and word of mouth.

> I vividly remember IE and many hacks to have css elements properly working in it… The common advice now is to only use CSS that is supported in the last two major versions of each major browser. You can check any css property's support... - Source: Hacker News / about 1 month ago
Thank you, heartfelt... For sharing an artwork, a miracle! Just in case, have you considered publishing the work at platforms as CodePen, where genius Artists/People express their art, too, as you?: // https://codepen.io/. - Source: Hacker News / 2 months ago
