Show IH: Toolbit — a unified, privacy-friendly developer toolbox

Hey everyone 👋

I’ve just launched Toolbit — a browser-based workspace that combines 20+ developer utilities (like JSON Formatter, Base64 Encoder, JWT Decoder, Markdown Previewer, and more) into one clean, consistent, ad-free app.

Everything runs entirely on your device — no network calls, no telemetry, no cookies, and definitely no ads. You can even install it as a PWA to use it offline.

🧠 The idea

I built Toolbit out of pure frustration.
As a developer, I was constantly switching between random “free online tools” — one to format JSON, another to encode Base64, another to preview Markdown, etc.

Most of them had:
• Ads everywhere
• Cookie pop-ups
• Sketchy privacy policies
• And inconsistent, clunky UIs

All I really wanted was one clean, trustworthy workspace where I could quickly format, encode, validate, and move on with my work — without losing focus or exposing data to who-knows-where.

That’s how Toolbit was born.

⚙️ What Toolbit does

Right now Toolbit includes more than 20 tools grouped by categories:
• JSON: Formatter, Schema Validator, CSV to JSON
• Web: CSS/JS Minifiers, HTML Escaper, URL Encoder, Markdown Previewer
• Encoding & Security: Base64 Encoder, JWT Decoder, Hash Generator
• Text: Case Converter, Word Counter, Diff Tool, Strip Whitespace

It’s all client-side — everything runs in your browser using React + Vite + TypeScript + Zustand + Tailwind.
No backend. No tracking. Just code running locally.

🎨 The design philosophy

I wanted Toolbit to feel like a workspace — not a website.
Each tool shares the same interface: a split view with input and output panels, consistent buttons, and keyboard shortcuts.

It’s built to be fast, distraction-free, and developer-focused.
There’s even dark mode, of course 🌙

⸻

🛠️ The stack
• React + Vite for a blazing-fast frontend
• Zustand for lightweight state management
• TypeScript for maintainability
• Tailwind CSS for clean, consistent styling
• PWA support for offline use

It’s deployed on Cloudflare Pages — simple and fast.

🔮 What’s next

I’m already working on the next step:
• A plugin-based architecture so anyone can add or build tools
• A Tauri-powered desktop version for Mac, Windows, and Linux
• Potentially open-sourcing Toolbit once the codebase stabilizes

Long-term, I want Toolbit to become the VS Code of small developer utilities — modular, local-first, and private by default.

💬 Feedback welcome

I’d love your feedback:
• What developer tools would you like to see next?
• Any interest in an open-source version or plugin SDK?
• How can I make this more useful for your daily workflow?
