What Is My Toolbox?
My Toolbox is a collection of 22 browser-based utilities built for people who'd rather get things done than hunt for the right app. Every tool runs entirely in your browser — your data never leaves your device, and there's nothing to install or sign up for.
We started this project in 2024 after getting tired of ad-heavy "free" tools that upload your JSON configs or passwords to unknown servers. The result: fast, private utilities that work offline once loaded. No tracking pixels, no email gates, no upsells.
Developer Tools
Format JSON with trailing-comma detection, encode Base64 for JWT debugging, generate SHA-256 hashes for file integrity checks, or test regex patterns with real-time highlighting. Built by developers who use these tools daily — so edge cases like 50 MB JSON files and multi-line regex are handled properly.
Financial Calculators
Run mortgage scenarios with extra-payment comparisons, calculate compound interest with the Rule of 72, or convert currencies using mid-market rates. Every calculator shows the formula it uses and lets you export results — no black-box math.
Converters & Utilities
Convert units across 10 categories, pick colors in HEX/RGB/HSL, generate QR codes up to 4,296 characters, or calculate BMI with WHO classification. Each tool is keyboard-accessible and works on mobile without layout shifts.
Why People Use My Toolbox
100% Client-Side Processing
Your data stays in your browser. We don't send anything to a server — check the Network tab yourself. No cookies, no analytics, no fingerprinting.
Actually Free, No Catch
No freemium limits, no "sign up to unlock" walls, no ads. The site costs us about $12/month to host on Vercel, and we're fine with that.
Zero Registration Required
Bookmark it, use it, close it. We don't need your email, and we won't ask for it. Ever.
Sub-Second Load Times
Static pages served from edge CDN nodes in 30+ regions. Typical first-paint under 400ms on 4G. No client-side framework hydration blocking your input.
