Why these tools are different

Every tool on Tools.ly runs as plain HTML, CSS and JavaScript in your own browser tab. There is no server doing the calculation, no database storing your input and no analytics script watching what you type. When you close the tab, the work is gone unless you chose to save or download it.

It keeps working when the network does not

Because nothing is computed remotely, a tool page that is already open keeps working with a flaky connection, on a plane, or on a locked-down work laptop that blocks third-party scripts.

Honest about limits

Several tools here — the body-composition and calorie estimators in particular — are estimates built on published formulas. They are a starting point for a conversation with a professional, not a diagnosis. Every page says so, and every page links to the sources it uses.

Built to be found and linked

Each tool has its own permanent address, a canonical URL, structured data and a breadcrumb trail, so search engines and other people can link to the exact tool rather than to a generic home page. See the full directory or read more about the project.
