Zed, a collaborative code editor, is now open source, with its code available under a copyleft license on GitHub. The company behind Zed believes that making it open source will help make it the best product and allow it to connect with a wider community of developers. Zed's UI framework, GPUI, is distributed under the Apache 2 license, allowing for its use in other desktop applications. The company plans to continue investing in Zed's development through a sustainable business model, including services that integrate with the editor.
