AllTools.dev is a modern, fast, free online toolkit built for people who need quick, accurate calculators and converters without signing up, creating an account, or wading through cluttered interfaces. The platform offers 500+ tools across finance (mortgage calculators, loan amortization, compound interest, currency conversion, debt payoff, retirement planning), health (BMI, calorie needs, pregnancy tracking, ideal weight, body composition), math (scientific, statistical, geometric, percentage, fraction), science and engineering, date and time utilities, unit conversions (volume, length, temperature, power, area), developer utilities (JSON, regex, JWT, hashing), and interactive math and algorithm visualizations. Every tool is free and works instantly in the browser. No accounts, no paywalls, no sign-in walls, no data collection beyond standard analytics. Calculations happen client-side for speed and privacy. Unlike older established calculator sites that grew through 20 years of ad-heavy layouts and outdated UX, AllTools.dev is built fresh on Astro with a clean, mobile-first, accessibility-conscious interface. New calculators ship weekly based on user demand. Ideal for: students doing homework, developers needing quick conversions, finance-minded folks planning loans and investments, professionals doing scientific or engineering calculations, and anyone who just needs a fast answer without installing an app.

I still have to try https://ci-en.net/, https://slushe.com/, https://ko-fi.com/, https://catbox.moe/, I heard they were possible good alternatives. But I couldn't say, dunno yet. Source: over 2 years ago
I did, however, remember another crowdfunding platform that may be the best of both worlds here (second highest voted so far being Patreon). Ko-fi: it offers both monthly and one-time donations as well as a store where we could sell things like early access keys or things like that. Their fees are very low as well, capping out at 5%.
