About the development tools
Tools for the small jobs that interrupt a working day: turning an SVG into code you can paste into a project, making sense of a timestamp from a log, or checking how a link will look once shared. They run entirely in your browser, so source files and data never leave your machine.
Built for copy and paste
Results are shown in the format you need and can be copied in one click, with options for the details that usually take a second pass.
Safe with real data
Nothing is sent anywhere. You can use production timestamps or proprietary artwork without worrying about where they end up.
