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.

Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:

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.

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
