Not too long ago, I found myself debugging an issue in production. All I needed was a quick way to decode a Base64 string and double-check a SHA256 hash.
That should take 10 seconds, right?
But instead:
- I ended up on some SEO-stuffed site
- Got hit with cookie banners and ads
- Clicked the “Decode” button… and the page tried to reload?
This shouldn’t be hard.
So I built ToolShelf — a collection of developer tools that are fast, privacy-first, and just work.
🛠️ What’s on the Shelf?
A handful of zero-bullshit tools — the kind I always wish I had open in a pinned tab:
- ✅ Hash Generator (SHA-256, SHA-3, MD5, HMAC, file hashing)
- ✅ Base64 Encoder/Decoder (text or file input)
- ✅ JSON Formatter (validate, beautify, JSONPath)
- ✅ Text Transformer (sort, trim, remove duplicates, change case)
- ✅ QR Generator (bulk CSV, logo upload, contact + WiFi support)
No login. No cloud. No servers involved in the actual tool logic.
Once you load a page, it even works offline.
🔐 What Makes It Different?
- 🕵️♂️ No tracking or user-level analytics
- ⚡ Blazingly fast, tiny payloads
- 🌗 Light and dark mode
- 🧩 Works in Firefox, Chrome, Brave, Edge — even on mobile
Just developer utilities — not disguised SaaS landing pages.
