Are these network and DevOps tools free?

Yes — every tool on this site is completely free to use, with no account, signup, paywall or usage limits. Open a tool and start typing.

Is my data uploaded to a server?

No. The tools run entirely in your browser, so tokens, passwords and text never leave your machine. The one deliberate exception is the DNS lookup, which sends your query straight to Cloudflare's public DNS-over-HTTPS resolver (1.1.1.1) — and nowhere else.

What tools are included?

A DNS lookup, an IPv4 subnet/CIDR calculator, a cron expression builder, Base64 and URL encoders, a JSON formatter, a JWT decoder, password/UUID/ULID generators, MD5 and SHA hash generators, a Unix timestamp converter, a regex tester, data-size and number-base converters, an OpenAPI spec explorer and a text encryptor — plus a DevOps cheat sheet.

Do the tools work on mobile?

Yes. Everything runs in any modern browser on desktop or mobile. Because the work happens client-side, the tools stay fast even on a slow connection.
