Rework the plugin system per docs/plugin_plan.md (P0–P8): - Extension-point registry (ide-extension) so new contribution types register without touching the kernel; languages, run detectors, providers, views and UI contributions go through it. - Per-plugin capability consent with a risk-graded ledger; process capabilities are pinned to resolved binary paths and hashes. - Async, actor-per-plugin Wasm runtime with lazy activation, cancellation, events, long-running tasks and idle reclamation. - Plugin host moved into ide-host, shared by local and remote projects. - Distribution: install/package tooling (openidea-plugin bin) and a static market index. - WIT frozen as openidea:[email protected]; Rust SDK with mock host. - Ten official validation plugins under plugins/official.
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.
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.
