- Restricted Mode git: reads run without a signature verifier, hooks (including config-defined ones), an external diff, filters or a lazy fetch, also inside submodules; every repository and every git starts restricted until the project is trusted. - project.write and plugin quick fixes cannot reach git's own files under any spelling or through links; project.write is a high-risk grant. - Built-in web server: each served root has its own port and token; a file outside the project is served with its folder minus dot names, or alone when that folder is the home folder or above it; no fixed port. - Images, references, Markdown links and language-server links reach no network share other than the one already open. - Marketplace: entries whose id or version no manifest may carry are dropped; an index read over the network names nothing on this machine; network reads are bounded in size and time. - Agent replies load remote images on a click; the Markdown preview and Mermaid configuration no longer fetch from other hosts.
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.
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.
