Most of us spend a fair chunk of the workday bouncing between tiny utilities. Format some JSON. Generate a QR code. Convert a unit. Count words in a paragraph. They are quick jobs, but the websites that host them are usually the opposite of quick: pop-ups, surprise paywalls, ads that follow your cursor, and a different design on every page.
ChrysoKit is our answer to that. A single home for the small tools you reach for every day, with a clean, consistent interface, a real dark mode, and zero login. Free now, free later, free always.
Why another tools website
We are not promising to reinvent the JSON formatter. The job here is to bring together the utilities most people actually use, build them well, and put them under one roof so you can stop tab-hopping. Same shortcuts, same theme, same feel across the entire kit.
Everything runs in your browser. We do not see what you paste in, what you generate, or what you convert. There is no account, no tracking pixel chasing you across the web.
What is in the kit today
Right now you can use ChrysoKit for:
- Developer tools like a JSON Formatter with auto-repair, tree view, deep diff and converters.
- Text utilities for counting, transforming and cleaning content.
- Calculators for discounts, currencies, units and BMI.
- Everyday utilities like password generation, QR codes and a Pomodoro timer.
Over fifty more tools are scaffolded and shipping in waves over the coming weeks.
What this blog will cover
Three things, mostly:
- Tutorials showing how to get the most out of each tool.
- Deep dives on topics adjacent to what we build, like security, productivity and developer workflow.
- Updates when we ship new tools or significant improvements.
How we built it
ChrysoKit is a static site, hosted on Cloudflare Pages. Each tool is a self-contained page, which means a bug in one tool can never break another, and pages load fast because there is almost nothing to load.
The design system is shared across the kit: the same warm editorial palette, the same components, the same shortcuts. New tools inherit it for free.
Privacy first. Every tool runs entirely in your browser. Nothing you type, paste or generate is sent to our servers, ever.
What is next
The short list: image tools, code tools, more converters, and a small set of AI-assisted helpers behind a clear opt-in. Bigger picture: keep the surface clean, keep the speed high, keep it free.
If there is a tool you wish existed, or a tool we have that could be better, the contact form is the place. We read every message.
