CodeStream is a Chrome extension designed to enhance collaboration within integrated development environments (IDEs) by seamlessly connecting GitHub pull requests and issues to popular coding platforms such as Visual Studio Code, Visual Studio, JetBrains, and Atom. This free tool allows users to manage pull requests directly from their IDE, facilitating code reviews and merges with ease.

The extension features a dedicated button for pull requests that opens the relevant PR in the CodeStream plugin, along with an option to automatically check out the PR's branch. Additionally, it provides a "Start Work" button on issue pages, enabling users to create feature branches and update their status on Slack, thus keeping team members informed about their current tasks.
