DevSexy

DevSexy brings 35 developer tools together for the small data, text and debugging jobs that interrupt a coding session. Use the free online toolbox in a browser, or choose the native Mac app when you want a focused offline workspace and quick Option-key access.

Format, validate and minify JSON before sharing a payload or checking an API response. The JSON workspace also offers a tree view, so it is easier to navigate nested data. For token inspection, the JWT tool can decode the header and claims locally. Decoding a token is not the same as verifying its signature; use the appropriate verification operation and key when authenticity matters.

Other utilities cover Base64 conversion, regular-expression testing, and text comparison. The text diff helps you inspect changes between two versions of a configuration or document. The regex tester lets you try a pattern and its replacement against sample text. Base64 is an encoding format, not encryption, so it should not be treated as a way to protect secrets.

For structured data there are tools for YAML and TOML, XML, and converting between common table formats such as CSV, TSV, JSON and Markdown. Additional tools include a HAR analyzer, an environment-file comparison workspace, and a QR code and barcode studio. These are useful when a task calls for a quick inspection or conversion without switching between unrelated sites.

The browser tools process the content you enter on your own device rather than uploading it for processing. DevSexy is useful for developers, QA engineers and technical teams who work with payloads, test data, text and configuration every day. The online tools are free and do not require an account.

DevSexy for Mac is a separate native application that keeps the toolbox available offline and supports Option-key shortcuts. It has a 15-day free trial, followed by a one-time license for the purchased version. The free browser toolbox remains available separately.
