Every tool runs in your browser. No sign-up. No paywall. No backend. Built by a solo founder in 7 days using AI and shipped on GitHub Pages.
Here is the deal: I was tired of every "free" developer tool requiring a sign-up, an email, a credit card, or hiding features behind a paywall. So I built my own. All of them.
In 7 days, using AI-assisted development (vibe coding), I shipped 200+ tools that run entirely in the browser. No backend. No database. No tracking beyond basic analytics. Every tool works the moment you open it.
The entire stack is HTML, CSS, and JavaScript hosted on GitHub Pages. Zero hosting cost. Zero maintenance burden. Pure tools that solve real problems.
Categories span everything: developer tools, SEO tools, social media growth, design tools, AI tools, business calculators, and more. If you build things on the internet, there is something here for you.
