About ATRX Dev
Practical browser tools for developers, technical teams, and anyone who needs to transform or inspect data quickly.
What We Build
ATRX Dev creates focused utilities for common tasks such as formatting JSON, converting YAML, testing regular expressions, working with Base64, calculating subnets, and generating stronger passwords. The goal is simple: make routine technical work faster without requiring an installation or account.
How the Tools Work
Most tools process input locally in your browser. When a tool must communicate with another service—such as the API Request Tester sending a request to an endpoint you provide—the page explains that behavior. See the privacy page for more detail.
Who Creates the Content
Tools and guides are maintained by the ATRX Dev Team. Content is reviewed for practical accuracy, updated when behavior or guidance changes, and corrected when an issue is identified. Our editorial policy describes that process.
