A computer system includes client devices operated by users collaborating on a project, and a collaboration server. Each client device remotely accesses web applications via a managed browser to be used by the users collaborating on the project. The collaboration server cooperates with the managed browsers to receive from the managed browsers data corresponding to actions performed by each user within the web applications, generate notifications based on the actions performed by the users within the web applications, and cause the managed browsers to display the notifications. The notifications are generated independent from the web applications.
