About FindTool
FindTool is a collection of 50 small, focused utilities for the things developers do dozens of times a week: making sense of a JSON response, decoding a token, converting a timestamp, testing a regular expression, cleaning up a list.
Why it exists
Tools like these already exist, but most of them are unpleasant to use. They are slow to load, covered in ads that outnumber the controls, interrupted by newsletter popups, or — worst of all — they quietly send whatever you paste to a server you know nothing about. Pasting a production API response or a bearer token into a site like that is a genuine security problem, and it happens constantly because the tools are convenient.
FindTool is the version of those tools we wanted to use: fast, plain, and honest about where your data goes.
How it works
Every tool on this site runs as JavaScript inside your own browser tab. There is no backend that receives your input, because there is no backend at all — the site is static HTML and JavaScript served from a CDN. When a page says your data is processed locally, that is a statement about the architecture, not a promise about our intentions.
You can verify this yourself: open your browser's network tab, use any tool, and watch that nothing is sent. Disconnecting from the internet entirely also works — every tool keeps functioning once the page has loaded.
What we do and do not collect
We use privacy-focused analytics that records aggregate pageviews, referrers, countries and device types. It sets no cookies and does not follow you between sites. We never collect, log or transmit the content you paste into a tool. The full detail is in the privacy policy.
How it is organised
Tools are grouped into 7 categories — JSON & Data, Encoding & Decoding, Generators, Hashing & Security, Date & Time, Text Tools, Web & Dev — and every tool page links to the handful of other tools you are most likely to need next. If you prefer searching, press ⌘K (or /) anywhere on the site.
How it is funded
FindTool is free and has no paid tier. It may carry advertising in future to cover hosting and development time. If that happens, ads will sit in clearly labelled places outside the tool interface — never disguised as buttons, never interrupting what you are doing, and never in a position that pushes the tool below the fold.
New tools
The tool list grows. If something you use regularly is missing, or an existing tool is missing an option that would make it genuinely more useful, tell us at [email protected]. Specific requests from people who would actually use the result are the best input we get.
