PyScripter is a free, open-source Python integrated development environment for Windows.
What PyScripter is
PyScripter is a free, open-source Python integrated development environment for Windows. Its editor includes syntax highlighting, code folding, completion, call tips, and syntax checking while typing. An integrated interpreter and debugger support remote debugging, conditional breakpoints, call stacks, variable and watch views, and post-mortem analysis. PyScripter also offers a unit-testing interface, automatic test generation, and refactoring tools for organizing imports, renaming, and extracting functions. Its file explorer integrates version control through Tortoise Git, SVN, or CVS, and external tools can include PyLint, TabNanny, and Profile. Built-in LLM assistance offers editor help and chat with OpenAI, Gemini, Grok, DeepSeek, and local models. OpenAI usage requires a paid plan or pay-as-you-go credit; light Gemini use is free, and Ollama runs local models. Windows users need Python 3.8 or newer. The 64-bit build requires 64-bit Windows and Python; the 32-bit build requires 32-bit Python. Portable zip packages need no installation.
