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.

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`](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](plugins/README.md) and
the [official plugins](plugins/official). The plugin API is still a preview.
