PyCharm is primarily a desktop integrated development environment (IDE) developed by JetBrains for Python development. It is available for Windows, macOS, and Linux operating systems.

As of my last update, there was no official online version of PyCharm provided by JetBrains. However, JetBrains does offer an online IDE called “Code With Me” that allows for collaborative coding sessions in various IDEs, including PyCharm.

Please note that the software landscape is constantly evolving, and there may have been updates or changes to PyCharm or JetBrains’ offerings since my last update. I recommend checking the official JetBrains website or other reliable sources for the most up-to-date information regarding any online versions or new features of PyCharm.
