Developer Tools
Essential developer tools: JSON formatter, password generator, and QR code generator. Free and browser-based.
The Developer Tools section on Adawix brings together the utilities every developer needs daily: a JSON formatter and validator, a strong password generator, a QR code generator, a URL shortener, a unit converter with over 80 units across 10 categories, a Base64 encoder/decoder, a SHA-256 and SHA-512 hash generator, a CSS gradient generator, and a Hijri/Gregorian date converter. Designed with an Arabic interface essential for the Arabic-speaking developer who prefers not to switch between scattered English tools.

Whether you are building an API, debugging a JSON response, or need a quick QR code for a meeting, these tools save you time. Try the JSON Formatter to clean server responses, or the Password Generator for new accounts.
Guide to the most-used developer tools
For frontend developers, the JSON formatter is essential when dealing with unformatted API responses. The tool detects structure errors instantly (extra comma, missing bracket, multiple quotes) and shows the exact location of the error. The CSS gradient generator saves time writing linear-gradient and radial-gradient manually through interactive gradient preview, and copy the code ready.
For backend developers and system administrators, the SHA-256 and SHA-512 hash generator is useful for verifying file integrity and creating API signatures. The Base64 encoder is essential when embedding images in CSS or sending binary data via JSON. The tools work on texts of any size at high speed because processing is local.
For UI/UX designers, the QR Code generator creates customizable codes with different colors and sizes, useful for linking social media posts to landing pages. And for everyone working in a bilingual environment, the Hijri/Gregorian date converter is essential when scheduling tasks between clients in the Gulf and international partners.

Common questions about developer tools
Can the tools handle large JSON?
Yes, the JSON formatter has been tested with files up to several megabytes. For files larger than 50 MB, the browser may slow down a bit — in this case use command-line tools like jq.
Are generated passwords really safe?
Yes, we use crypto.getRandomValues() which provides true cryptographic randomness (CSPRNG) from the operating system, not Math.random() which is predictable. The generator also works locally so no one sees the password but you.
Do hash tools save entered texts?
No. All calculations are done locally with the Web Crypto API. No storage, no server transmission, no tracking. Suitable even for sensitive texts like secret words and API keys.
