Developer tools for everyday coding
From API debugging to markup cleanup, DroidXP offers focused utilities that run in your browser — ideal when you need one job done well without opening a heavy IDE or CLI environment.
Format, validate, and transform data
JSON and XML show up in logs, webhooks, and config files. The JSON Formatter and XML Formatter help you pretty-print, minify, and catch syntax errors with line hints when the engine provides them.
Encoding helpers — Base64, URL encoding, and Unix timestamps — remove friction when reproducing bugs or writing test fixtures.
HTTP, HTML, and front-end debugging
The HTTP Request Builder and HTTP Status Code reference support quick API experiments. For markup, try the HTML Beautifier, HTML Minifier, and Viewport Resizer when tuning responsive layouts.
Service workers and storage APIs appear in modern apps. Explore the Service Worker Generator, Local Storage Manager, and Browser Storage Viewer during PWA or offline-first work.
Regex, snippets, and safe experimentation
Regular expressions are powerful but easy to get wrong. The Regex Tester runs patterns against sample text in real time. The Code Snippet Generator and HTML Boilerplate Generator give you paste-ready starting points with sensible defaults.
For education and quick checks, the JS Function Tester evaluates small expressions locally. It is not a substitute for unit tests or a secure sandbox for untrusted code.
Frequently Asked Questions
Is my source code uploaded?
Most developer tools on DroidXP process input locally in JavaScript. Check each tool page for network-related features.
Which tool should I use for JSON errors?
Start with the JSON Formatter's validate mode — it reports parse errors and often highlights the failing line.
Do you store my pasted data?
No server-side storage for local tools. Clearing your browser tab removes in-memory content unless you save it yourself.
