* feat: Second pass aligning interactions with IntelliJ IDEA Result tool windows - Next/Previous Occurrence (⌥⌘↓/↑) across Find, Usages, Problems, TODO, Inspection and Hierarchy, with an "N of M" status hint - Find: reuse the unpinned tab, Pin Tab, source preview, group by file or directory, exclude moves to the next result, Rerun - Usages: tabs with pinning, exclude and preview - Problems, TODO, Inspection: no autoscroll by default, severity-first sorting, context menu with quick fixes and copy description - Trees: F4/⌘↓ jump to source; speed search Home/End and arrow handling Find in Files, bookmarks, navigation - Replace mode: Enter replaces the selection, ⇧⌥Enter replaces all, multi-select - Pin Window toggle, highlighted read-only preview, search/replace history (⌥↓), Alt mnemonics, search context filter (comments / string literals) - Mnemonic bookmarks (⌥F3, ⌃⇧digit, ⌃digit), ⌘F3 bookmarks popup, descriptions, ⌘-click gutter toggles a bookmark - Select In popup (⌥F1); Recent Locations double-click and Delete; Search Everywhere remembers the query per tab Code insight and refactoring - Extract/Introduce continue with in-place rename and name suggestions; expression and occurrence choosers with live highlighting - Safe Delete confirms first; numbered Refactor This - Quick Documentation history, in-popup links and a Documentation tool window; Quick Definition switches between targets and shows the whole declaration - Goto chooser lists symbol names and can pin to the Find window - Parameter Info Tab/⇧Tab, intention preview, Reformat dialog and summary, inlay hint ⌘-click and context menu - Live templates: Enter moves to the next field, two-step Esc, ⌘J as a lookup, language surrounders with mnemonics - File Structure popup as a filterable tree; Show Usages filter and preview; call hierarchy jumps to call sites Editor - Paste re-indents each line by default; Move Statement moves whole statements in and out of blocks and re-indents - Type over closing quotes of existing strings; ⌘D/⌘⌫ cover folded regions; ⌥⌫ deletes the preceding word - ⌃G / ⌃⌘G whole-word rules and wrap hint; double-modifier caret cloning - Visual-column block selection, nested Collapse All, recursive folding, fold selection toggle, Go to Matching Brace, gutter drag selects lines, sticky line and error stripe clicks, Insert toggles overwrite mode Run, VCS, workbench - Gutter icons show the last test result; Modify Run Configuration; test tree hides passed tests, context menu and assertion diff - Stack frames resolve by fully qualified class name; context run chooser - Inline Smart Step Into - Git Log multi-select filters, "me" and date range; favourite branches, Fetch and tags in the branch popup; stash Keep index and Unstash options - Terminal tab titles follow the shell; Distraction Free persists; gear menu; sticky balloons move to the notifications tool window after a while * fix(vcs): Label restored local changes as yours after Smart Checkout; name the branch checked out Conflicts from restoring stashed changes show the user's uncommitted changes on the left like other operations, and the checkout notification names the new branch instead of the previous one. * fix: Close the merge editor on Apply; confirm before terminating a running Run tab Like IDEA, applying a merge result closes its tab, and closing a Run tab whose process still runs asks before terminating it (with a Settings toggle and "Do not ask again"). * fix(terminal): Don't start a new session in the background after closing the last tab The hidden Terminal window stays mounted, so it reopened a session as soon as the last tab closed. It now opens the Local tab only once the window is shown again, as IDEA does. * fix(vcs): Start the merge result from a three-way merge; close the editor on Apply The result pane now begins with non-conflicting changes merged and each conflict showing the base text, resolved from the side panes, instead of raw conflict markers. Apply now reports success, so the tab closes. fix(search): Match File Structure filter on word starts * fix: Limit Smart Step Into to the paused line; drop usages hints on callbacks; show full intention titles Adapters that list every remaining call in the function (debugpy) made Smart Step Into fall back to a chooser that offered calls from later lines. Targets are now narrowed to the calls on the paused line, so they are picked in place. Anonymous functions and callbacks no longer get a 'no usages' hint, and intention titles are no longer cut short when there is room for them. * fix: Undo / Redo from the Edit menu and Find Action use the editor's history They ran the webview's native undo, which misses programmatic edits such as templates, completion and refactorings, so nothing happened in the editor.
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.
