About HexSlate

HexSlate is a set of small tools that run inside your browser tab. No account, no subscription, no upload.

Why it exists

Every tool here already existed somewhere else. The good ones sit behind a subscription, the free ones want an account before they will format a bit of JSON, and a lot of them post whatever you paste to a server you know nothing about. That is a poor trade for a JWT carrying a live session, a config file with credentials in it, or a customer's data.

Each tool takes your input, does the work in the tab you already have open, and shows you the result. There is no server to send anything to. Open your browser's network panel and watch, or pull your connection after the page has loaded and keep working.

What that means in practice

• Text you type, paste or drop into a tool is never transmitted. It is processed by JavaScript on your own machine.
• Files are the same. The hash generator and the Base64 encoder read the file you pick with the browser's own file API; the bytes never go anywhere.
• There is nothing to sign in to, so there is no account and no email to give.
• Every page is plain HTML that works with a keyboard and a screen reader, and keeps working on a slow connection.

How it pays for itself

HexSlate counts page views and whether a tool was used, which is how what to build next gets decided. What you typed is not part of that. It runs without cookies unless you accept them, and declining the bar stops it entirely.

No ads run today. When they do, they will pay for the hosting and the domain, they will be asked for separately from analytics, and they will not be placed above the tool you came for.
