I’m a full-stack developer, and I recently got frustrated with the current state of online calculators. Most of the top search results are bloated with heavy ads, slow to load, and have clunky, outdated UIs.
To solve this, I’m building Bunny Calculator: a growing suite of clean, fast, and completely free web calculators.
It is currently still in active development, but the core tools are up and running. My goal is to build a high-utility, ad-free "single source of truth" for everyday calculations (financial, health, conversions, etc.) without the terrible user experience.
I built this using [Insert your tech stack here, e.g., Next.js, Tailwind CSS, and Cloudflare Workers]. Focusing heavily on performance and programmatic SEO structure so each calculator has its own dedicated, lightweight page.
I’m sharing it here early because I’d love to get your harsh feedback before I do a wider launch:
UI/UX: Is the interface as intuitive as it should be?
Utility: What niche or obscure calculators do you find yourself constantly searching for that I should add to the roadmap?
Bugs: If you manage to break any of the current formulas, please let me know!
Thanks for taking a look.
