About Developer Tools
Developer tools speed up common coding tasks — formatting JSON, encoding data, generating unique IDs, testing regular expressions, and more. Instead of switching between multiple terminal commands or online tools, you get everything in one place.
Softzar covers the essentials: a JSON formatter and validator, Base64 encoder/decoder, UUID generator, color converter, URL encoder/decoder, MD5 hash generator, and regex tester. Each tool is built for developers by developers — fast, keyboard-friendly, and privacy-first.
All processing happens in your browser. Your code, data, and API payloads never leave your machine.
How to Use Developer Tools
Select the developer tool for your task. Paste your input (JSON, text, URL, or code) into the editor. Results appear instantly — formatted output, encoded string, generated ID, or validation feedback.
Frequently Asked Questions
Is my code or data sent to your server?
No. Every developer tool runs entirely in your browser using JavaScript. Your JSON payloads, Base64 strings, URLs, and other data never leave your device. This is especially important when working with sensitive API keys or private configuration files.
How large of a file can I process?
Processing limits depend on your browser's memory. Most JSON files up to 10MB work fine. For very large files, the browser may slow down. Since everything is client-side, there are no artificial server limits.
What regex engine does the tester use?
The regex tester uses JavaScript's built-in RegExp engine, which follows the ECMAScript specification. It supports most common patterns including lookaheads, lookbehinds, named groups, and the 's' (dotall) flag. Results show match count, matched text, and capture groups.
