A focused collection of small developer utilities designed to stay fast and easy to use.
OpenUtility brings common formatting, encoding, conversion, generation and text utilities into one simple browser workspace.
The current tools are implemented in the page itself. The site does not require an OpenUtility account or a server-side workspace to use the tools.
OpenUtility is hosted as a static website and is designed to work well on both desktop and mobile browsers.
What the current OpenUtility website stores and what it does not.
The current implementation contains no application code that sends tool input to an OpenUtility API. Formatting, conversion, decoding and other tool operations run in the browser.
Favorites, recently used tools, per-tool history and tool requests are stored in your browser's local storage. They are not submitted to an OpenUtility server by the current implementation.
Some navigation and sharing features use the URL. Avoid putting confidential information into a URL if you do not want that information included in a link you share or saved in browser history.
The current page loads fonts from Google Fonts. Your browser therefore makes requests to Google's font infrastructure. If you want a fully self-contained deployment, the fonts can be self-hosted in a later performance/privacy pass.
Hosting, DNS, HTTPS, GitHub Pages and your browser may create ordinary network requests and logs. This page does not claim that the website can prevent those platform-level requests.
