We’ve all been there: you need to format a quick JSON with an API token, validate a test card for your checkout, or compare two code snippets. You Google it, click on a random portal, and immediately get hit with cookie banners, 10 flashing ads, and the uncomfortable feeling that your input is being logged by a remote server.
To solve this for myself and the developer community, I built TipTools (https://tiptools.com.br).
Why Client-Side Only?
Most utility sites could be entirely static, yet they process your data on backend endpoints. On TipTools, we made an architectural commitment:
- Your data never leaves your machine: Calculations, regex parsing, Luhn algorithms, and formatting run exclusively inside your browser via client-side JavaScript and native Web APIs (like Web Crypto).
- Instant Performance: Since there are zero server roundtrips, results render in the very millisecond you type or paste.
-
Command Palette (
Ctrl + K/Cmd + K): You don't have to navigate through endless menus. Just hit the shortcut and find what you need.
What's included?
- Data & Dev: JSON Formatter & Minifier, SQL/HTML/XML/CSS formatters, Base64 encoder/decoder, JWT viewer, and Diff Checker.
- Security & Testing: Gateway sandbox test cards (Stripe, Cielo, Mercado Pago with approved/declined/3DS scenarios), Strong Password Generator, UUID v4/v7 generator.
- Design & Media: Color palette & HEX/RGB/HSL converter, QR Code Generator with SVG/PNG export, SVG optimizer.
- Finance & Utils: Currency converter, percentage calculators, and text cleaners.
The Tech Stack
- Framework: Next.js (fully static SSG export)
- Styling: Tailwind CSS with Dark/Light mode support
- Icons: Lucide React
- Hosting: Vercel (Edge CDN)
