About

Practical developer utilities with clear privacy boundaries.

DevUtils.uk is maintained as an independent utility site for developers, QA testers, technical support teams, documentation writers, and students. The site focuses on small everyday tasks such as formatting JSON, encoding values, generating UUIDs, converting timestamps, creating hashes, comparing text, testing regular expressions, and inspecting JWT payloads.

Who makes DevUtils.uk?

The site is operated by the DevUtils.uk editorial and engineering maintainer. The goal is to publish useful tools and original tutorials in plain English, with enough context to help readers understand what each utility does and where its limits are.

What happens to tool input?

The homepage tools are implemented with client-side JavaScript. Normal input is processed inside your browser tab. DevUtils.uk does not provide user accounts, file storage, server-side parsing, or cloud execution for these tools. You should still avoid pasting secrets, private customer data, production access tokens, or confidential files into any website.

Advertising disclosure

DevUtils.uk may show clearly labeled advertising. Ads are kept separate from the tools, navigation, and tutorial content. The site does not ask visitors to click ads and does not design tools around ad interaction.
