* perf(vfs): list directories off the main thread and reuse the repository lookup Opening a folder on a network share (\\wsl.localhost\<distro>\...) is slow because every listing ran on the main thread and walked up to the repository root and ran a repository discovery again. - fs_read_dir runs on the blocking pool. - GitignoreStack::cached keeps the repository root and the repo-level rules for a few seconds. An edit of .git/info/exclude is still seen at once (its mtime and size are checked) and every .gitignore / .ignore is read fresh. Refs #916 * feat(remote): open WSL projects through a WSL transport A folder of a WSL distro (\\wsl.localhost\<distro>\... or \\wsl$\...) now opens as a remote project whose openidea-server runs inside the distro, so the terminal, SDK discovery, run, language servers and git are native Linux. - RemoteTarget (ssh | wsl) replaces the SSH configuration id in the remote launch, connection, session and recents; old recents are read as SSH and a WSL target never inherits the legacy trust migration. - remote_wsl: probe the distro, stream the server into ~/.openidea/server and start it with `wsl.exe -d <distro> --exec <bin> --stdio`. Distro names are validated and every command goes through --exec with positional arguments. - wsl_distros / wsl_resolve commands; File > Open, the CLI and recents route WSL folders to the distro and focus the window that already has them. - Remote Development dialog: SSH/WSL choice with the detected distros; the status bar shows `WSL: <distro>` / `SSH: <host>`. - ide-jsonrpc: skip the NUL left at the start of a line by UTF-16 output of wsl.exe, which made the first message of the server disappear. Not run on Windows yet: only a stand-in for wsl.exe is tested. Refs #925, #327, #721 * fix(remote): satisfy clippy in WSL output decoding * style(run): format run types * fix: regenerate bindings and drop untranslated WSL catalog entry * test(i18n): list WSL as an untranslated product name * fix(run): pick build wrappers and shell quoting by the execution host A remote window runs commands on its Linux or macOS server, so a Windows desktop no longer selects gradlew.bat, mvnw.cmd or Windows quoting for it. * fix(welcome): open legacy WSL UNC recents and sessions through the distro Recents and the restored session called the local openProject for a \\wsl.localhost folder saved before WSL projects, which fails with OS error 123. They now resolve it like the other entry points. * fix(windows): keep WSL files out of remote project launches path_launch tested the WSL share before is_dir, so a first-instance CLI launch with a WSL file opened a remote project instead of LightEdit. * fix(remote): run-command OS comes from the remote host, not an assumption The server's OS was dropped after connect, so a restored session had none and isWindows() assumed every remote host is Unix. Keep it on the connection and the session, and resolve it through hostOs(). --------- Co-authored-by: NguyenBang <nguyenbang@NTBANG.local> Co-authored-by: NguyenBang <nguyenbang@Mac.lan> Co-authored-by: l0ng-ai <24760907+l0ng-ai@users.noreply.github.com>

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.
