* fix(plugins): run process: programs through their PATH-found link resolve_program canonicalized the found file, so a symlinked cargo (rustup, asdf, mise and other multicall shims) resolved to the shim itself: Command::new then ran rustup with cargo's arguments. The link is what dispatches on argv[0], so keep it as the pinned path. The grant still pins the target's content: hashing through the link reads the file it points to, and relinking or replacing either still fails the approved-file check. Fixes #2001 * fix(plugins): canonicalize the dir, not the program link CI showed the middle ground is needed: tests (and the pins file) compare against canonicalized paths — /var → /private/var on macOS — but the file name itself must stay the PATH-found link so multicall shims dispatch on argv[0]. Canonicalize the parent only. * fix(ide-plugin): set file_action in windows-only test action The CodeAction struct gained a file_action field but this windows-only test fixture was not updated, breaking the Windows build (E0063). A plain action is not a file action.
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. 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.
