About Spyder

Spyder is a free, open-source IDE for scientific Python, maintained by a community of volunteers and funded by donations and sponsors. Its layout will feel familiar to anyone coming from MATLAB or RStudio: an editor, an IPython console, a variable explorer for inspecting arrays and data frames, a plots pane, help and a profiler, all in one window. It runs code cell by cell, offers code completion and linting through a language server, and integrates debugging and static analysis. Plugins add features such as notebook support and unit testing. Spyder is MIT-licensed and runs on Windows, macOS and Linux, through standalone installers or Python package managers like conda and pip. It suits scientists, engineers and students doing data analysis who want an interactive environment without the weight of a full IDE. It is not designed for large application development, web frameworks or heavy refactoring.

Best for: Scientists and students doing interactive data analysis in Python.
