Overview

The jq playground is a powerful tool designed for testing jq queries against JSON data directly within your web browser. Built with Next.js, it leverages WebAssembly technology for seamless processing, allowing users to work with JSON data securely without relying on server-side interactions. With its unique blend of features, this playground makes exploring and manipulating JSON easier than ever, while prioritizing user privacy.

In an age when data security is paramount, the jq playground stands out with its ability to process data locally. Users can create and share jq snippets with ease, generating unique URLs that preserve their queries while maintaining local execution. This ensures that your data remains within your control, giving you a safe and efficient environment for your JSON querying needs.

  • Local Data Processing: Processes JSON input directly in the browser, keeping your data private and secure from the outset.
  • Shareable Snippets: Generates unique URLs for shared queries while executing them locally in the recipient’s browser.
  • Easy Setup: Requires only Node.js, npm or yarn, and PostgreSQL to get started, with simple commands to clone and run the application.
  • Development Mode: Includes a hot-reload feature for an enhanced coding experience while developing your queries.
  • Production Build Ready: Offers a straightforward method for creating a production-ready version to utilize locally without complications.
