The task is usually small, but the input may still contain project names, internal endpoints, or other details that should not leave the browser.</p> <p>I rebuilt <a href="https://utihub.com/" rel="noopener noreferrer">UtiHub</a> around a narrower idea: focused developer tools that work immediately, require no account, and keep supported tool input local.</p> <h2> Starting with JavaScript minification </h2> <p>The first workflow I concentrated on was JavaScript minification. The current <a href="https://utihub.com/tools/javascript-minifier" rel="noopener noreferrer">JavaScript Minifier</a> uses Terser and provides:</p> <ul> <li>minify and beautify modes;</li> <li>ES2015, ES2020, and ES2022 targets;</li> <li>optional compression and name mangling;</li> <li>module parsing;</li> <li>local <code>.js</code>, <code>.mjs</code>, and <code>.cjs</code> file input;</li> <li>source and output byte comparison;</li> <li>copy and download actions.</li> </ul> <p>The important constraint is that UtiHub does not upload or execute the source. Processing happens in the browser tab.</p> <h2> Applying the same constraint to other tools </h2> <p>That same principle applies to tools such as the JSON Formatter, URL Parser, JWT Decoder, Regex Tester, and Base64 Encoder/Decoder.</p> <p>The difficult part was not adding more utilities. It was reducing the product to a promise people could understand: private browser tools for everyday developer tasks.</p> <p>You can try the <a href="https://utihub.com/tools/javascript-minifier" rel="noopener noreferrer">JavaScript Minifier</a> or browse the full collection at <a href="https://utihub.com/" rel="noopener noreferrer">UtiHub</a>.</p> <p>I would appreciate practical feedback: which developer task would you still avoid doing in an online tool, even if it claimed to process data locally?</p> webdev javascript privacy showdev
