* perf(vcs): filter the Git log with git log instead of a background search index The log built a persistent inverted index of every commit's message, authors and changed paths in the background, with a progress bar above the commit list, and walked trees itself to filter by path. Building it took minutes on large repositories, and filters were slow until it finished. - Text: plain text uses `git log --fixed-strings --grep` (with `--regexp-ignore-case` unless Match Case is on); text of 4+ hex digits also matches hash prefixes. Regex filters still match in-process. - Paths: `git log -- :(literal)<paths>` replaces the in-process path walk and its per-commit tree cache. It uses git's history simplification and, when the repository has a changed-path commit-graph, its Bloom filters. Glob characters in a path are literal. - Authors match against the commit metadata cache. - Removed the search tables, `index_log`, the `vcs_log_index` command and the indexing progress bar. The commit metadata cache stays. * docs(contributing): ask for screenshots only when a change alters what users see Removing a feature together with its UI, copy-only and non-visual changes now describe what was checked instead of attaching before/after screenshots. * fix(vcs): match case-insensitive non-ASCII Git log text in process git folds case only for ASCII under the C locale it runs with, so a case-insensitive filter like "ärger" missed "Ärger". Such text is now matched against commit messages directly. Path and text selection also ignore log.showSignature and log.follow from the user's config.
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.
