Tools for everyone who keeps the web running.

Yes. All 70 tools run with no account, no payment details and no usage limit. Open a tool, enter your domain, IP or text and get an instant result. We build these utilities as an open toolbox for DevOps and web professionals, not as a funnel with a paywall behind it.

The team behind Uptimeify, a monitoring platform for agencies and MSPs. The same people who run our probing infrastructure build these tools, because we rely on them in our own daily work. The collection stands on its own: you need no Uptimeify account to run a WHOIS, an SSL check or a JSON formatter.

Check domains and DNS, validate SSL certificates and email setups, test networks, format code and data, convert between formats and calculate SLA or bandwidth figures. The collection spans domain, DNS, sysadmin, developer, validation, formatter, cloud, content, converter, thread-dump and status tools. Use the category filter at the top to reach the right utility faster.

No. Formatters, converters and generators run directly in your browser, so your input never leaves your device. Tools that need a live query, such as DNS, WHOIS or SSL checks, reach the target host from our European infrastructure. Everything is hosted in Frankfurt, on a European stack without US sub-processors with data access.

Yes. The collection grows around what users ask for. If a utility is missing, tell us: we prioritise what web professionals need most often in daily work. The suggestion button sits at the bottom of the page.
