Arnaud Ritti a5db5cdda8 fix(smoke): allow graceful server shutdown before forced cleanup (#2054)
The smoke harness killed the server's process group right after closing its stdin, so the host never got to shut down and tool processes it had spawned in their own groups could be left running. Close now waits for the server's graceful EOF shutdown (bounded at 15 s), then kills the server's own group and every independent tool group it owned, reporting group-kill errors only after cleaning the rest. Covered by `smoke/server.test.ts` (graceful, failed initialize, hung shutdown, signal exit, spawn failure, missing `ps`, coalesced frames, kill errors).

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.
