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. On Windows, if you'd
rather skip the installer, each release also ships a portable zip — unpack it
and run `openidea.exe`.

## Benchmark

Opening [freqtrade](https://github.com/freqtrade/freqtrade) (Python, ~770 files)
with warm caches, median of 5 runs:

|                             | OpenIDEA          | IntelliJ IDEA 2026.2.3 |
| --------------------------- | ----------------- | ---------------------- |

| 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          |

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.
