Plugin API 1.3 adds what commit-message generators and before-commit checks need: - `menu = "commit.message"`: a plugin command, with the plugin's icon, in the toolbar above the commit message of the Commit tool window and the Commit dialog. - `commit.pending-commit()` (`vcs.read`): what Commit would commit right now, per file its repository, path, status and a `git diff` of only the included files and changed blocks against HEAD (1 MiB in all), plus the message, Amend and a revision. The diff is made by the same selection the commit uses, in a copy of the index, so the index and the working tree stay as they are; unsaved editors of the included files are saved first, as Commit does. Only in trusted projects. - `commit.set-commit-message(revision, message)` (`vcs.write`): replaces the message only while the draft is still at that revision, so text the user typed meanwhile is never overwritten (`stale`). - `[[contributes.commitChecks]]` and the optional `commit-checker` export (worlds `plugin-commit-checks` / `commit-checks`): checks listed in Commit Options (on by default, `vcs.commit.disabledPluginChecks` turns them off) and run after the IDE's own; their problems, optionally with a location, stop the commit until Commit Anyway. The window answers the host through `CommitRequested` / `plugin_answer_commit`, also for remote windows. The Rust SDK gains `host::pending_commit`, `host::set_commit_message`, `openidea_plugin::commit` and their mock; a `commit` test fixture exercises them. All components are rebuilt for the WIT change.

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 (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.
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 and
the official plugins. The plugin API is still a preview.
