Benchvale

Tools that run in your browser

Once a tool has loaded, you can disconnect and keep working. Benchvale is small utilities for designers, developers, marketers, and teachers. Each one runs inside the page, so nothing you type is sent to a server and no account is needed. That claim is tested on every build.

Who maintains this

Aaron Wilson. Tools ship when they are ready, and the changelog records what a visitor would notice. Once a tool has loaded, you can disconnect and keep working. How we build tools names the build-time network check that fails a release if a tool page starts transmitting what you type.

Three pages that show the same rule in different jobs: how thick a patio slab should be, whether the end date counts, and Wheel of Names alternatives.

What is coming

The rest of the roster is built one cluster at a time, and a cluster ships with its anchor tool first: writing, kitchen, units, numbers, files, money, fitness. The changelog records what landed and when.

Why another tools site

Most free utilities are one of two things. Either they upload what you paste to a server you know nothing about, or they work fine until they ask you to make an account to keep your own data. Both are avoidable for this kind of tool, because the work is arithmetic and text handling that a browser does perfectly well on its own.

So the rule here is that the computation stays on your device, saving anything is optional and local, and every tool says plainly what it does with what you give it. Where a tool genuinely cannot work that way, it will say so rather than quietly dropping the claim. How we build tools explains how that is enforced.
