Message dialogs: `Dialog` gets an `icon` (question / info / warning / error) that renders IDEA's alert layout: no title bar, a 32px icon, bold title, text, checkbox under it. Every confirmation helper (prompt, VCS, services, project tree, keymap, LSP choices, run, database, Replace All) uses it. Open Project matches IDEA: "This Window" is the default and has focus. The Code Analysis and TODO commit checks default to Review. Project widget: the title bar project button opens a popup like IDEA's ProjectWidget, with Open… / Clone Repository…, the projects open in other windows (new `window_open_projects` command) and recent projects, filtered by typing. Chinese UI: UI text stays written in English and is translated through a source-text catalog (`locales/text/zh.json`, about 2300 strings). The UI primitives (buttons, checkboxes, selects, tabs, dialogs, menus, tooltips, toasts, settings labels and hints) translate the strings they are given. Action titles and categories are localised in the registry, and static JSX text uses `<T>`, so text follows a locale switch without a reload. The Settings window now syncs the locale too. Settings search matches both languages. Claude-Session: https://claude.ai/code/session_01B65qLEKnkeYTGdbwhLpjCu

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.
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.
Build
pnpm install
pnpm tauri dev
Rust 1.96, Node 22, pnpm and the Tauri prerequisites.
