About
Built for developers.
Designed for privacy.
What is ToolKit?
ToolKit is a free collection of browser-based utilities for developers, designers, and anyone who works with text, code, or data. Every tool runs entirely in your browser — no server receives your input, no database stores your data, no third party is involved.
The project started from a simple frustration: too many online tools are slow, ad-heavy, require account creation, or quietly log your inputs. ToolKit is the opposite — fast, clean, private, and free.
How it works
Every tool uses native browser APIs — the Web Crypto API for password and hash generation, JSON.parse() and JSON.stringify() for the JSON Formatter, crypto.randomUUID() for UUIDs. No external libraries handle core tool logic.
You can verify this yourself — open your browser's Network tab while using any tool. You'll see no outbound requests for the tool computation itself.
What we collect
We use Google Analytics to understand which tools are most useful, how users navigate the site, and where to focus development. Analytics data is anonymized and aggregated — we see page views and session counts, not individual user content.
We do not collect, store, or transmit any content you enter into the tools. Your passwords, code, text, and other inputs never leave your browser. Read the full Privacy Policy.
What's coming next
We're actively building more tools — QR code generator, timestamp converter, text diff checker, color converter, CSS gradient generator, and more. All 15+ planned tools are listed in the tools directory as coming soon.
