JSBin by Remy Sharp is a lightweight, browser-based code playground designed for quick HTML, CSS, and JavaScript experimentation. Built with speed, simplicity, and sharing in mind, JSBin is ideal for front-end developers, educators, and support teams who need to rapidly prototype or troubleshoot code in real time.

- Live Code Preview: Write HTML, CSS, and JavaScript and instantly see the results in a side-by-side preview window—no compilation or reloads needed.

- Code Panel Customization: Open and close individual panels for focused work, and adjust the layout to match your preference and screen size.

- Library & Framework Injection: Quickly add jQuery, Angular, React, and other popular libraries with one click—perfect for testing specific use cases.

- Shareable URLs: Every bin generates a unique URL, making it easy to share code snippets with collaborators, clients, or support forums.

- Collaborative Editing: Edit bins with others in real-time for pair programming, debugging sessions, or live teaching.

- Version Control & History: Save versions of your bins and fork others’ work to iterate or customize shared examples.

- No Installation Required: 100% browser-based—just open and code. Great for quick tests and mobile-compatible editing.

JSBin is ideal for front-end developers, QA engineers, educators, and anyone who needs a fast, reliable place to test or share live code snippets.

JSBin is a nimble, no-frills sandbox for real-time front-end development. Whether you’re troubleshooting a layout bug, teaching code live, or just exploring a new idea—JSBin is always ready to go.
