I've been building EveryTool (everytool.solutions) — a browser-based utility platform where every tool runs 100% client-side. No accounts, no uploads, no ads.
Just shipped 3 new tools:
→ Text Diff Checker — paste two text blocks, instantly see line-by-line differences. Built for devs comparing configs, code snippets, or API responses. → Length Converter — metric ↔ imperial, instant real-time conversion as you type. → Temperature Converter — Celsius, Fahrenheit, Kelvin.
The Length and Temperature tools are the first in a brand new Unit Converter category — the platform's 5th category alongside Image, PDF, Developer, and Calculator tools.
We're now at 35+ tools. The entire stack is Next.js App Router + TypeScript + TailwindCSS on Vercel. All tool logic is implemented natively (Web Crypto API, native JS) — zero external library dependencies for core functionality.
The main thesis: most online utility tools are slow, ad-filled, and untrustworthy. I'm building the alternative — fast, private, and permanent (no paywalls mid-session).
Happy to get feedback on the tools, UX, or the direction of the platform.
What unit converter or developer utility do you find yourself Googling most often?
