Quick fixes - Errors get a red quick-fix bulb; Apply Quick Fix (⌥⇧↵) fixes the most severe problem at the caret, and the error hover offers the fix directly. - Code generated by a code action is re-indented to the file's style. - Python: Implement abstract methods (⌃I or the bulb) from the bases. - Duplicate code actions are listed once. Completion - Overloads sharing a name, and a name importable from several modules, are no longer merged into one entry. - Auto-import entries show the module they import from. - Call snippets without a stop (`new ArrayList<>()`) leave the caret inside the parentheses with parameter info, or past them when nothing takes arguments; parameter info also opens after server call snippets. - The selected item is resolved ahead of acceptance, so its auto-import is applied (rust-analyzer). Navigation and diagnostics - Language server requests wait for pending edits, so Go to Declaration right after typing answers for the current text; an empty answer right after an edit is retried while the server catches up. - Diagnostics come back after a window reload; error underlines stay visible under typo / unused highlighting. - Implementation gutter markers no longer refresh in a loop while the server reports progress. - A missing alternative server no longer shows as a server error.
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.
Build
pnpm install
pnpm tauri dev
