Free, fast, privacy-first developer tools — built by developers who were tired of slow, bloated alternatives.
Every developer uses micro-tools daily — decoding a JWT token, formatting a JSON response, converting a timestamp, generating UUIDs for test data. The existing tools online are slow, full of intrusive ads, and some even send your data to their servers. We built DevUtils because developers deserve better.
Every tool on DevUtils runs 100% in your browser using JavaScript. Nothing you type, paste, or upload ever leaves your device. There are no accounts, no server-side processing, and no data logging. You open a tool, use it, and leave. That is it.
DevUtils is a static site hosted on a global CDN. Pages load in under 1 second. There are no heavy JavaScript frameworks, no render-blocking requests, and no unnecessary dependencies. We use vanilla HTML, CSS, and JavaScript because your tools should load instantly — not after a 3-second spinner.
DevUtils is built and maintained by a small team of full-stack developers who use these tools every day. We build what we need, test it ourselves, and publish it for free. If a tool is not fast enough for us, it is not fast enough for you.
