About ToolzKit
ToolzKit is a digital utility workspace: 52 small, single-purpose tools that do one job quickly and then get out of the way. Format a payload, decode a string, generate a credential, work out a percentage — the things that interrupt real work several times a day.
Why it exists
Most of these utilities already exist somewhere on the web, but they are usually buried under advertising, gated behind a sign-up, or slow enough that opening a terminal is faster. ToolzKit was built around the opposite trade-off: load fast, work immediately, keep the interface dense enough that everything you need is on one screen, and never ask who you are.
The second reason is trust. Pasting a configuration file or an API response into a random website means handing that content to someone else’s server. Wherever a task can be done with the browser’s own APIs — and for the overwhelming majority of these tools it can — the work happens in your tab and the data never leaves your device.
Who it is for
- Developers debugging a payload, reformatting a query, testing a pattern or generating a fixture.
- Writers and editors counting words, cleaning up a messy paste, comparing two drafts or fixing inconsistent capitalisation.
- Marketers building campaign links, drafting meta tags and turning headlines into clean URL slugs.
- Everyone else who occasionally needs a percentage, a date difference, a colour conversion or a QR code.
Product principles
- 01 Every tool works. Nothing is a mock-up, and nothing is marked “coming soon”.
- 02 Local by default. If a task can run in the browser, it does.
- 03 Honest about limits. Each tool page states what it cannot do as clearly as what it can.
- 04 No account, no lock-in. Your favorites and recent tools live in your own browser storage and can be cleared at any time.
- 05 Keyboard first. The command palette opens with a single keystroke from anywhere on the site.
