Help › About showed no version, build or runtime in untrusted project windows and on the welcome screen. Root cause: the restricted-mode allowlist added with project trust missed app_build_info and other application-level commands, so they were rejected wherever the window had no trusted project; the frontend then cached the failed build info for the whole session. Fix: classify all registered commands and allow the 24 that only read application information or change the user's own application state (build info, log location, update checks, cache invalidation, file clipboard, JDK download, Docker settings, database export paths, patch export, system environment); JDK download now uses the application tool directory instead of project tool settings. Execution commands (run, build, debug, language servers, tool install from project settings) stay blocked. Build info is retried after a failure instead of being cached. Verified on macOS in an untrusted project and on the welcome screen; Windows not run. Related to #519

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
Rust 1.96, Node 22, pnpm and the Tauri prerequisites.
Native notebook execution tests are opt-in and need two distinct Python environments
with ipykernel installed:
OPENIDEA_TEST_PYTHON=/first/env/bin/python \
OPENIDEA_TEST_PYTHON_SECOND=/second/env/bin/python \
cargo test -p ide-notebook --test kernel_runtime -- --ignored --test-threads=1
