JetBrains PyCharm Overview
PyCharm Professional is JetBrains' commercial Python IDE for Windows, macOS, and Linux, building on the free Community edition with tooling for full-stack and data work. On top of PyCharm's strong Python code intelligence — completion, type inference, refactoring, and an integrated debugger — the Professional edition adds support for web frameworks such as Django, Flask, and FastAPI, JavaScript and front-end development, database tools, remote and SSH interpreters, Docker integration, and scientific features including Jupyter notebook support. It is aimed at professional Python developers and data scientists who want one environment for code, web, and data. It is sold by subscription with a free trial. The offline installer is the full setup and installs without a network connection. This page points to the genuine JetBrains PyCharm source from JetBrains s.r.o., not a third-party host.
