* fix(tools): find Python on Windows without python3.exe

Installing debugpy on Windows failed with "cannot run python3.exe … (os error 3)": the tool
manager looked for `python3` first, and on Windows that only finds the App Execution Alias in
WindowsApps, which can't start without the Store's Python. Windows installs `python.exe` and the
`py` launcher instead. On Windows the interpreter is now looked up as `python`, `py`, then
`python3`, and a WindowsApps alias only counts when it runs. The debugpy adapter's default
interpreter is `python` on Windows too. macOS and Linux keep `python3` first.

* fix(tools): keep searching past broken Python aliases

OpenIDEA brings the IntelliJ IDEA way of working — its keymap, its tool windows, its search-everything habits — to a native app with a Rust core.

Editor, code insight, debugger, Git, terminal, database and HTTP clients, for 60+ languages. Builds for macOS, Windows and Linux.

Benchmark

Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:

OpenIDEA IntelliJ IDEA 2026.2.3
Window with the project 0.9 s 3.1 s
Ready (CPU settled) 1.1 s 13.2 s
Memory (USS, all processes) 169 MB 2011 MB
CPU time until ready 2.4 s 47.9 s
Idle CPU 4 % of a core 7 % of a core
Quit 0.3 s 5.9 s

A release build of OpenIDEA from main and IDEA with default settings and plugins, on Windows 11, 32-core AMD, 62 GB RAM. IDEA analyses Python more deeply, so "ready" doesn't mean the same work on both sides. Both are measured from the outside, the same way: see perf/compare to run it on your machine and projects.

Plugins

Plugins add actions, completion, quick fixes, tool windows, custom editors, themes, file icons and languages. They run as sandboxed WebAssembly components; themes, icon themes and languages need no code at all.

Install them from Settings › Plugins, or start your own with openidea-plugin new — see Writing OpenIDEA plugins and the official plugins. The plugin API is still a preview.
