Framed! is a free add-on for Chrome, Firefox, and Opera that allows web developers to visually separate different web hosts by adding custom frames. This tool is especially useful for developers who work with multiple environments that look similar.

With Framed!, you can easily differentiate between a safe-to-experiment development server and a live server, reducing the risk of making mistakes. You have the flexibility to choose the color, width, and opacity of the frame edges, giving you a better understanding of the environment you are working in.

The key features of Framed! include the ability to add custom hosts with support for wildcards, match host IP addresses, add custom colors to each host, adjust the opacity of the frame, define custom border edge widths, and set the z-index for the borders. Additionally, you can import and export your frames for use in other browsers or for backup purposes.

If you are a web developer looking for a simple yet effective way to visually distinguish between different web hosts, Framed! is the perfect tool for you.
