Marimo Can Now Run in PyCharm

The first version of the marimo plugin, which enables reactive notebooks in the Python development environment PyCharm and JetBrains IDEs, has been released. Developers can add notebooks to existing projects without leaving the IDE, allowing them to test code or build interactive demos.

Key features include:

• Live code updates: Through marimo's module reloader, editing library code automatically updates dependent cells in the notebook, providing a fast feedback loop.
• VCS-friendly structure: Since notebooks are saved as regular .py files, they can be efficiently managed alongside project code using version control tools like Git.
• Sandbox mode: Leveraging uv, it supports a sandbox feature that runs notebooks in an isolated environment without polluting the project environment.
• AI agent collaboration: Through marimo-pair, you can pair-program on notebooks together with AI agents such as Claude and Codex.
