Plugins can now ship a web page as the UI of a view or custom editor (`web = "web/index.html"`), so editors built on web libraries are plugins rather than part of the core. - Web views: every file under the page's directory is part of the package (checked, copied on install, covered by the digest and signature) and served through the `openidea-plugin` URL scheme, under a per-revision path with a CSP of its own, into an `<iframe sandbox="allow-scripts">`. An update or reinstall reloads open pages. - Frame bridge (`window.openidea`), shared by html bodies and web pages: theme, messages to the plugin's code, `document.get/edit/replace/onChange` (versioned edits that join the text editor's undo history, Save and dirty state), `saveFile`/`openFile` through the IDE's dialogs, and IDE shortcuts the page leaves alone. - Custom editor layouts: tab, split (Editor and X) or preview over the text editor, switchable from the tab's actions. - New points `fileIcons` and `fileTemplates`; new optional capability `clipboard` for web views. - Excalidraw official plugin: `.excalidraw` / `.excalidraw.json` open as an interactive canvas kept in step with the file's text, with self-hosted fonts, PNG/SVG export, images, file icons, a New Drawing template and JSON highlighting. Closes #732. - Fixes: a lock-order deadlock between listing plugins and refreshing project pins; the dev server ignored edits under `src/features/plugins`. - `plugins/build.sh` builds and checks web pages; CI typechecks and tests them.

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.
