Abstract: System and methods for collaborative workspaces for content browsers are provided. In one embodiment, a method for a collaborative content browser comprises: obtaining a network address for a workspace management document; opening, at a browser, the workspace management document from a shared network resource based on the network address, the workspace management document recording a browser state for rendering a collaborative browser workspace in the browser; executing a browser process to generate a workspace shell for the workspace by rendering structural features of the workspace shell based on the browser state, the structural features including an user interface with a browser tab; synchronizing project resource data from the browser state to render network content from a project resource in the browser tab; and communicating an update to the browser state based on a change applied at the browser to the structural features or the project resources.
