About Botoi

Botoi builds free online tools that run entirely in your browser. Every formatter, converter, calculator, and generator on this site processes data client-side using JavaScript. Your input never touches a server.

Why Client-Side?

Server-side processing introduces latency, privacy risk, and scaling costs. Browser-based tools eliminate all three. The tool responds instantly because there is no network round-trip. Your data stays private because it never leaves your device. And the site can serve millions of users from a static CDN without any compute infrastructure.

No Account Required

Botoi does not require sign-ups, email addresses, or personal information. Bookmark any tool page and return whenever you need it. No login walls, no premium tiers, no feature gating.

Built With

The site is built with Astro for static site generation, Preact for interactive components, and Tailwind CSS for styling. It deploys to a global CDN for fast page loads worldwide.
