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

• Hash generator (SHA-256, SHA-512)
• RSA key pair generator & X.509 certificate inspector
• BIP39 seed phrase generator
• Password generator & strength checker

Developer utilities

AI & LLM tools

• Prompt tokenizer and token calculator
• Context trimmer and prompt compressor
• AI response cleaner and text humanizer

VFX & camera (yes, really)

• 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.
