A plugin system built on WebAssembly components (wasmtime, WASI p2), with a typed WIT API (`openidea:plugin@1.0.0`) and a Rust SDK, shipped as a preview. - Extension points declared in `plugin.toml` (commands, languages, themes, icon themes, menus, key bindings, status items, settings, views, custom editors, file icons and templates, run detectors, editor providers), validated before anything takes effect and projected onto the workbench's own registries: plugin themes and file icon themes are chosen in Settings › Appearance and Quick Switch, plugin shortcuts are edited in Settings › Keymap, plugin problems are grouped in Settings › Inspections. - Capabilities with risk levels and consent at install, pinned `process:` programs, secrets in the OS keychain. - Runtime: one thread per active plugin, fuel/time/memory budgets, soft and hard deadlines on the editing path, cancellation, crash backoff, idle reclaim, a precompiled-component cache; remote projects run code plugins on `openidea-server`. - Web views and custom editors with a sandboxed page, a document bridge joined to the text editor's undo history, and split or preview layouts. - Distribution: signed `.oiplugin` packages, a static marketplace index with revocation, versioned installs with rollback, install from a `.zip` or a folder. The release workflow signs and publishes the official plugins and their index, which released builds use as the default marketplace. - Official plugins: String Tools, Key Promoter, Git Toolbox, AI Completion, Checkstyle, MyBatis Navigator, CSV Editor, Solidity, Material Icons, Harbor Night, Excalidraw, Graphviz, Regex Tester, License Header.

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.
