Mux is a tool for developers that allows them to manage tasks with multiple AI agents. It integrates with VS Code, offers isolated workspaces, and supports rich markdown outputs. The application is open-source and available for macOS and Linux.

Void is an open-source alternative to Cursor that allows users to utilize AI agents on their codebase, checkpoint changes, and visualize modifications while ensuring data privacy. The project, which is a fork of the vscode repository, is currently paused as the team explores new AI coding concepts. Users can get involved through the Discord channel and contribute to the project's development.

Microsoft has open-sourced the GitHub Copilot Chat extension for VS Code under the MIT license, allowing the community to access its full implementation and telemetry mechanisms. This move is part of Microsoft's plan to integrate AI features into the popular code editor, which has seen significant growth in the open-source AI ecosystem. While the original GitHub Copilot extension remains closed for now, Microsoft plans to transition its functionality into the open-source chat extension in the coming months.
