This page is designed to help you find out whether BentoUtils is good and if it is the right choice for you.
BentoUtils is a library of 238 free calculators and converters, each one built to answer a single specific question well instead of bundling everything into one bloated app.
It exists because the alternatives were never actually free: ad-ridden calculator sites, tools that require a login just to use once, or ones that let you run something free exactly one time before asking for payment. BentoUtils was built to fix that, one tool at a time.
Every tool runs entirely in your browser. Nothing you type or upload is ever sent anywhere, and there's no tracking. Most tools need no account at all.
The catalog spans: - Electronics — Resistor Color Code Calculator, Ohm's Law - Woodworking & construction — Board Feet Calculator, Rafter Length Calculator - Finance — Freelance Rate Calculator, Invoice Generator, Mortgage Overpayment Calculator - Developer tools — Regex Tester, Cron Expression Builder, Unix Timestamp Converter - Design — Color Contrast Checker, Typographic Scale Generator - Hobbies — brewing, fitness, 3D printing, and more
The free tier gives 20 uses a day per tool, no signup required. A $10/month Pro plan (normally $15) removes that daily cap and unlocks every tool as it ships, including new ones added after you subscribe.
Built with vanilla JavaScript and Web Components, no framework, no bundler. It runs as an installable Progressive Web App and works offline once loaded.

No per-tool subscription and no upload step. One login, only needed for the Pro plan, covers all 238 tools instead of a separate account or app for each calculation.
238+ single-purpose calculators and converters in one place, instead of a different site for each one. Every tool runs client-side, nothing you type or upload is ever sent anywhere, and most need no account.
Hobbyists and tradespeople solving one specific problem: electronics hobbyists decoding resistor bands, woodworkers pricing lumber, homebrewers dialing in a recipe. Freelancers and developers make up the rest, using the finance and dev-tool calculators.
Vanilla JavaScript, Web Components, and CSS, no framework, no bundler, no TypeScript. Deployed as a Cloudflare Worker PWA, with Cloudflare KV for license tokens, Stripe for checkout, and Brevo for magic-link email.
I kept running into the same problem: every calculator site was covered in ads, needed a login just to use once, or let you run it free exactly one time before demanding payment. None of them were actually free to use. So BentoUtils started as a way to fix that, one tool at a time. It's now 238 calculators and converters, all usable with no login at all, and a free tier generous enough to rely on day to day.
