Adds Tomcat Server › Local run configurations for WAR applications: installation validation and version detection, Maven/Gradle WAR artifact discovery and build before launch, WAR file or exploded-directory deployment, context path and HTTP port, project JDK or a chosen JRE, VM options, environment variables and opening the browser. Each configuration runs with its own CATALINA_BASE in the project cache (HTTP, shutdown and local JMX ports configured there); Stop requests a clean shutdown before the usual process timeout. Debug attaches the Java debugger over JDWP. Update Application (Cmd+F10) updates resources, classes and resources with HotSwap, redeploys or restarts the server. Configurations are grouped under Tomcat Server in the configuration tree and Services. Not verified on a real Windows machine; command construction is unit tested. Fixes #205
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.
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
