What lives in Dev & Data Tools
Dev & Data Tools covers the faster, more technical side of the site: developer helpers, QA shortcuts, data generators, and simple lookup-style utilities that are useful during builds, testing, staging, and troubleshooting.
These tools are designed for moments where you want a quick answer or a reusable output without opening a full local workflow, writing a script, or installing a package for a small one-off task.
That makes them especially useful for developers, testers, product teams, and anyone who regularly needs identifiers, mock data, or quick technical checks in the browser.
How to get more value from these tools
Use the lightweight tools for speed, but treat them as practical helpers rather than replacements for full development or infrastructure workflows when accuracy or depth matters more than convenience.
For example, a UUID generator is ideal when you need IDs immediately, while a test data generator helps you generate test data for fixtures and demos without touching real user data. A public IP checker is useful for quick network sanity checks rather than deep diagnostics.
Over time, this section should feel like a compact but genuinely helpful set of technical browser tools, not just a list of thin utilities.
