LazyJJ is a Rust-based terminal user interface designed specifically to streamline workflows for the Jujutsu (jj) version control system. It functions as a thin wrapper that executes CLI commands in the background while providing an interactive graph, diff previews, and bookmark management. A standout feature is its rebase popup, which simplifies complex stacked-change operations by offering explicit movement modes. The tool prioritizes keyboard-driven navigation and integrates directly with Jujutsu’s native configuration and safety features like the operation log. While it offers significant ergonomic improvements, its performance is inherently tied to the speed of the underlying subprocess calls. Development milestones indicate the project is cross-platform and includes specialized integrations, such as a dedicated Neovim plugin.
