Every developer has a folder of bookmarks for one-off tools —
a JWT decoder here, a Base64 encoder there, a cron expression
tester somewhere else. Half of them send your data to a server
you know nothing about.
I built Wizbit.to to fix that.
What it is
95+ free developer utilities, all running 100% in your browser.
No server ever sees what you paste. No account. No ads. No limits.
What's inside
Data & encoding
- JSON formatter, beautifier, minifier & validator
- Base64 encoder/decoder
- CSV → JSON, CSV → Markdown, YAML ↔ JSON converters
- ENV file parser and ENV → JSON/YAML converter
Security & crypto
- JWT decoder with expiry checker and claims differ
- Hash generator (SHA-256, SHA-512)
- RSA key pair generator & X.509 certificate inspector
- BIP39 seed phrase generator
- Password generator & strength checker
Developer utilities
- Regex tester with live match highlighting
- Cron expression builder and syntax decoder
- SQL formatter
- Webhook visualizer and Stripe webhook simulator
- UUID/GUID generator (v4, v5, v7, bulk)
- HTTP status explorer
- CIDR subnet calculator
- Semver comparator
Frontend & CSS
- SVG → JSX converter and SVG cleaner
- CSS shadow, clip-path, and glassmorphism generators
- Color converter (HEX, RGB, HSL)
- Bezier curve and spring physics playground
AI & LLM tools
- Prompt tokenizer and token calculator
- Context trimmer and prompt compressor
- AI response cleaner and text humanizer
VFX & camera (yes, really)
- Depth of field visualizer
- LUT .cube file 3D visualizer
- ACES color space matrix calculator
- Timecode and frame arithmetic calculator
- Focal length / FOV / crop factor matcher
Why it's different
Most online dev tools are thin wrappers around a server call.
That's fine for public data — but when you're pasting a JWT,
an RSA private key, an ENV file, or a seed phrase, you're
trusting a server you've never audited.
Wizbit processes everything locally. The code runs in your tab.
Close the tab and it's gone.

I understand the intention behind the title, but all online websites are hosted on web servers.
"Your text, tokens, keys, code, and any other data you enter are never sent to any server..." is copy on the website that, to my knowledge, does not hold.
