What Thonny is

Thonny is a free Python IDE designed for beginners, with downloads or installation instructions for Windows, macOS, and Linux. Its starting interface omits features that may distract new learners. The editor highlights syntax errors and variable occurrences and distinguishes local variables from globals. Learning views can show variables, function call frames, and variable scopes. An integrated debugger steps through programs without requiring breakpoints and can display expression evaluation. Thonny includes a graphical package manager and a system shell prepared for Python commands, while bundled installers include Python 3.14. Windows installers support 64-bit Windows 10 and 11, with a separate Windows on Arm installer. Intel and Apple silicon installers require macOS 10.15 or later. Since version 5.0, Linux installation uses system Python and creates a virtual environment instead of providing a binary bundle. That release also ended 32-bit Windows installers and the XXL bundle. Plug-ins are available, but the developers do not endorse or take responsibility for them.

Who it suits

It suits beginners learning Python who want a focused editor, visual debugging, and built-in package tools. It also supports experienced users who need Windows, macOS, or Linux installation options.

What it does well

  • Free beginner-focused Python IDE
  • Debugger works without breakpoints
  • Bundled installers include Python 3.14
  • Graphical package manager included
  • Windows, macOS, and Linux support

What to know first

  • No 32-bit Windows installer
  • No published Linux binary bundles since version 5.0
  • XXL bundle no longer published
  • Plug-ins lack developer endorsement

Limits

Linux installation creates a virtual environment instead of using a published binary bundle. Thonny 5.0 no longer publishes 32-bit Windows installers or the XXL bundle.
