Tool arsenal
Pick the utility that matches the job in front of you
The bench covers QR, JSON, password, encoding, hashing, auth, timestamp, regex, design, and content utilities.
QR Code Generator
Generate QR codes for URLs, text, Wi-Fi, and contact cards with download-ready output.
Password Generator
Generate strong passwords with configurable length, symbols, exclusions, and multi-copy output.
JSON Formatter
Format, validate, minify, and inspect JSON payloads for APIs and debugging work.
Base64 Encoder & Decoder
Encode and decode Base64 or URL-safe payloads without leaving the browser.
Hash Generator
Generate MD5, SHA-family, CRC, and Adler hashes for integrity and verification tasks.
JWT Decoder
Decode JWT headers and payloads, inspect claims, and read expiration timestamps.
UUID Generator
Generate one or many RFC-compliant UUID v4 values for APIs, databases, and jobs.
Timestamp Converter
Convert Unix timestamps to readable dates and back with timezone-aware output.
Regex Tester
Test patterns, toggle flags, and highlight all matches against live input.
URL Encoder / Decoder
Encode query values and decode percent-escaped URLs for API and redirect debugging.
Color Palette Generator
Create monochromatic, analogous, triadic, and complementary palettes for product and UI work.
Lorem Ipsum Generator
Generate placeholder paragraphs, sentences, words, lists, and article-length filler copy.
Made for instant feedback
Everything runs client-side or via lightweight APIs, so formatted JSON or encoded payloads appear in milliseconds.
- ⚡ Keyboard shortcuts on every tool
- 📊 Session stats to keep teams informed
- 🧠 Smart defaults for faster iteration
Designed like a product, not a side project
The experience layers subtle gradients, depth, and responsive states so the UI looks at home in any modern dev workflow.
- 🎨 Glass panels + neon accents
- 📱 Mobile-first breakpoints
- 🌙 Dark mode native from the ground up
Privacy first by design
No registration, no telemetry creep. Sensitive payloads stay local, and tools degrade gracefully when offline.
- 🔒 Local-only JSON transforms
- 🧾 Transparent rate limits
- 🤝 Open roadmap + community votes
