How do I mask sensitive data in JSON or YAML files before sharing?▼

Data masking securely hides sensitive information in JSON, YAML, or text formats by matching key names or regular expressions. This allows you to safely share data samples without exposing actual secrets or passwords.

Can I test REST APIs and generate cURL commands directly from my browser?▼

API testing supports sending requests with custom headers, bodies, and authentication using various HTTP methods. You can view responses, status codes, and automatically generate cURL commands for easy replication.

Does this utility support Base64 encoding and multiple hashing algorithms?▼

Base64 encoding and decoding supports text or files, URL encoding, and various hashing algorithms. This functionality is useful for data transformation and performing security checks directly in the browser.

Do I need to install any external applications to use these developer tools?▼

No external applications or complex setups are required. This suite provides essential browser-based developer utilities built with React and Vite, running entirely client-side for immediate access.

What is the best way to mask specific fields using regular expressions in my data?▼
