Nimbalyst is a free interactive visual editor and session manager designed for users working with Claude Code. It enables collaboration on various formats, including markdown, mockups, diagrams, CSV files, and code. Users can manage multiple sessions simultaneously, linking files directly to specific sessions, which makes it easier to find and continue work without losing track of progress.

Developers benefit from integrated tools that support coding, reviewing, and committing changes within sessions. The platform includes git management and embedded terminals, streamlining workflow for those who regularly work with version control. Overall, Nimbalyst aims to enhance productivity by providing a comprehensive environment for managing code and project files effectively.
