Plugin API 1.3 adds an optional semantic-tokens-provider export (world plugin-semantic-tokens). A plugin declares the semantic-tokens kind under [[contributes.providers]] for any language, including ones it does not contribute, and returns single-line tokens with LSP token kinds and modifiers. The host asks it with the other editor providers (50 ms / 500 ms) when the editor requests semantic tokens and joins the result with the language server's: plugin tokens replace the server tokens they overlap, so the colour scheme styles them like any semantic token. Declaring the kind needs engines.openidea ^1.3. API 1.2 shipped with 0.1.38, so wit/ and the SDK's copy, ENGINE_VERSION and both API_VERSION constants move to 1.3 and every shipped component is rebuilt. The SDK gains openidea_plugin::semantic_tokens, and register_plugin! accepts any combination of optional exports (providers, views, indexing, syntax, semantic_tokens) instead of a fixed list of pairs.
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.
