About ToolBox
A free, privacy-first collection of browser-based tools built for people who value their time and their data.
Our Story
ToolBox started from a simple frustration: every developer has a dozen bookmarked tool sites, each with its own ads, cookie banners, and signup walls. A JSON formatter here, a Base64 encoder there, a password generator somewhere else. We wanted one clean, fast place for all of it.
So we built ToolBox - a growing collection of 168+ free online tools that run in your browser. Most tools process data entirely client-side. A handful of tools (like DNS Lookup, SSL Checker, and Grammar Checker) use lightweight server proxies to reach external APIs, but we don't log or store your data. Free tools require no account. Pro features require a login.
We launched in early 2025 and have been adding new tools every week based on what developers and designers actually need. Our goal is simple: be the only toolkit you need to bookmark.
Our Principles
Privacy by Design
Most tools run 100% in your browser. A few tools use server proxies to reach external APIs (DNS, SSL, grammar check, etc.), but we don't log or store your data. We don't use cookies, tracking pixels, or analytics that identify you.
Core Tools Free
Every core tool is free to use without limits or signup. Pro unlocks power features like batch processing and AI tools, but the essentials are free forever.
Speed First
No server round-trips means instant results. Tools load in milliseconds and process your data at the speed of your device. We optimize every component for performance.
Quality Over Quantity
Every tool is carefully built with attention to edge cases, accessibility, and user experience. We'd rather have fewer excellent tools than hundreds of mediocre ones.
How We Build ToolBox
ToolBox is built with Next.js and deployed on Cloudflare Pages for global performance. Every page is statically generated at build time, meaning zero server-side computation when you visit.
We use Tailwind CSS for styling with full dark mode support, TypeScript for type safety, and client-side JavaScript for all tool logic. The site scores 100/100 on Lighthouse for Performance, Best Practices, and SEO.
We track anonymous page views with Umami (a privacy-friendly analytics platform that doesn't use cookies or collect personal data).
