Editing and folding
- Move Caret to Code Block Start / End with Selection, Auto-Indent Lines,
Move Element Left / Right (swaps call arguments, parameters and list
entries).
- Fold Code Block folds the {...} block around the caret; Expand to Level
and Expand All to Level 1-5.
- Custom folding regions (//region, #region, <editor-fold>) fold to their
description; Navigate > Custom Folding lists them.
- Error Description shows the problems at the caret; Next / Previous
Highlighted Usage steps through usage highlights.
- Editor tooltips stay below the editor's top edge, so hints on the first
lines no longer hide under the tab bar.
Navigation, project and run
- Navigate > File Path lists the file and its folders to reveal in the file
manager.
- Copy... (F5) opens the Copy dialog for the selection or the open file; the
project view's Refactor submenu gets Copy File.
- Debug... chooses a configuration to debug; Quick Evaluate Expression shows
the selection's value in an expandable hint.
- Inspect Current File runs the inspection without the scope dialog.
- Surround with Live Template lists only $SELECTION$ templates; Java gets
Callable, read / write lock and iterate templates.
Windows
- Stretch the active tool window left / right / up / down, Restore Default
Layout, Go to Next / Previous Splitter, Close Active Tab on a second key,
Stop Background Processes.
All actions have default shortcuts in both keymaps, VS Code preset entries,
main menu items and Chinese translations.
The IDE you know, rebuilt in Rust.

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.
