* fix(java): pass m2e an effective settings file carrying the configured local repository (#1739) m2e resolves the local repository from the Maven settings XML, never from -Dmaven.repo.local, so JDTLS imports kept downloading into ~/.m2/repository even when the IDE's own mvn runs honored the configured path. When a local repository is configured but the user settings lack <localRepository>, derive an effective settings file under <root>/.openidea/ and pass it as java.configuration.maven.userSettings. Settings that already declare <localRepository> are passed through untouched. * fix(agents): notify subscribers when a session report changes the cached provider config (#1490) Session reports (session/new, session/load, turn updates) and CLI discovery funnel through Shared::remember_inner, which cached new model lists but never emitted AgentEvent::Providers. The composer therefore kept showing a stale model list until the next task's busy-to-idle refresh. Emit Providers when the cache actually changes; unchanged reports stay silent, and the cache lock is released before invoking the sink. fetch_settings' unconditional emit is now covered by remember_discovered and removed.
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.
