Developer tools you can trust with the data you can't paste anywhere else.
toolhq is a small collection of developer and design utilities that run entirely in your browser. Format JSON, test a regex, convert a color, generate a UUID, and get back to work.
every tool follows the same rules
- The logic runs on your machine, never on a server.
- Your input is never uploaded, logged, or stored.
- No accounts, no sign ups, no cookies beyond a single theme preference.
- No analytics that follow you around the web.
- Each page is statically generated and usable the moment it paints.
- The three tools that need the network say exactly where your data goes.
Why another tool site
Most online utilities are wrapped in ads, popups, and trackers, and many quietly send your input to a server. That is a real problem when the thing you are pasting is an API response, a token, or unreleased work. toolhq exists to be the version of these tools you can trust with that data.
The site is built to be fast: each tool page ships only the JavaScript it needs and is usable the moment it paints. If a tool ever feels slow or gets in your way, that is a bug. Found one, or want a tool added? I would like to hear about it.
Who builds this
toolhq is built and maintained by Jameel Haider, a developer who got tired of pasting API responses into tool sites that upload them. Every tool and every guide on the blog is written and maintained by him, tested against the real behavior of browsers, DNS resolvers, and mail servers rather than copied from other reference sites.
