    Paste your data

    JSON, a token, a color, a cron expression. It is processed right in your browser, not on a server.

Your data never leaves
your browser.

Local by default

Formatters, decoders, and generators run as plain JavaScript on your machine. Turn off your wifi and they still work.

No tracking, no accounts

No analytics, no ad pixels, no sign ups. The in-browser tools store nothing; the webhook inspector keeps captures in a temporary store for up to 24 hours, then deletes them.

Safe for secrets

JSON, tokens, and unreleased work are safe to paste into the local tools. There is no server on the other end to leak them.

Questions

Asked often, answered plainly.

Is toolhq really free?

Yes, every tool is free with no usage limits, no premium tier, and no account to create. The site exists because these tools should just be available.

Is my data uploaded anywhere?

No. The tools run as JavaScript in your browser, so what you paste never leaves your machine. The few tools that need the network (like the API tester and DNS lookup) say exactly where requests go, right on the page.

Do the tools work offline?

Most do. Once a tool page has loaded, formatters, converters, encoders, and generators keep working with no connection at all, because there is no server involved.

Is it safe to paste API keys, tokens, and production data?

For the local tools, yes: there is no server on the other end to log or leak them. Each tool states its privacy behavior in a badge at the top of the page, so you always know before you paste.

How is toolhq different from other online tool sites?

No ads, no popups, no cookie walls, no accounts, and no tracking. Tools load instantly, the privacy promise is real, and the whole site is built to get you back to work as fast as possible.
