Like most developers, I often find myself switching between a dozen tiny web utilities — JSON formatters, Base64 encoders, JWT decoders, Markdown previewers, URL encoders, and so on.
They’re scattered across the internet, each with their own design quirks, ads, cookie banners, and data collection scripts. Half the time, you can’t even trust what happens to your input once you paste it in.
💡 Introducing Toolbit
Toolbit is a browser-based, local-first workspace that brings 20+ developer tools together in one clean, consistent, ad-free interface.
It’s fast, private, and simple — designed for developers who value focus and trust.
⚙️ What Toolbit Does
Toolbit includes a curated set of essential developer utilities, grouped into categories:
JSON Tools
- JSON Formatter & Validator
- JSON Schema Validator
- CSV to JSON Converter
Web Utilities
- CSS Formatter/Minifier
- JavaScript Minifier
- HTML Escape / Unescape
- URL Encoder / Decoder
- Markdown Previewer
Encoding & Security
- Base64 Encoder/Decoder
- JWT Decoder
- Hash Generator (MD5, SHA, etc.)
Text Utilities
- Case Converter
- Word Counter
- Strip Whitespace
- Diff Tool
Every tool runs entirely on your machine — nothing is sent to a server. You can even install Toolbit as a Progressive Web App (PWA) and use it offline.
🧠 Why I Built It
I’ve been working on various projects where I constantly needed little utilities — formatting JSON, encoding text, comparing strings. My workflow looked something like this:
- Google “JSON formatter online”
- Click a random site
- Close two popups and decline cookies
- Paste my JSON, then hope it doesn’t get logged somewhere
After doing this for the hundredth time, I realized:
I don’t need “a bunch of online tools” — I need one unified, local-first workspace that never touches the network.
That’s how Toolbit started — as a small personal project, then evolved into a cohesive workspace.
🧩 Tech Stack
Toolbit is built using:
- React + Vite — for a fast, modular frontend
- TypeScript — for type safety and scalability
- Tailwind CSS — for a consistent, responsive design
- PWA support — so it can run offline and be installed like a native app
Everything is client-side — no backend, no database, no telemetry.
This makes Toolbit effectively “serverless” in the best sense: it literally doesn’t need one.
🔮 What’s Next
The current version focuses on predefined tools, but I’m already working toward a modular, plugin-based architecture — so developers can build and share their own tools easily.
That will make Toolbit not just a collection, but a platform for local-first developer utilities.
Also on the roadmap:
- Split view / multi-tab support
- Native desktop apps (Tauri or Electron)
- Open-source release
- User feedback integration
🏁 Try It
You can try Toolbit right now:
It’s free, ad-free, and everything runs locally in your browser.
You can even “install” it as an app and use it offline.
❤️ Feedback Welcome
Toolbit is something I built out of pure developer frustration — and joy.
If you try it, I’d love to hear your thoughts:
- Which tools should I add next?
- How can the UX improve?
- Any interest in open-sourcing it?
Let’s build a better developer workspace together.
