Run configuration detection only looked for pom.xml / build.gradle(.kts) at the opened root, so a Maven or Gradle build in a subfolder produced no configurations, and Java files fell back to a single-file `java X.java` launch without classpath or build. Detection now takes the root build, or else the shallowest build on each branch up to three levels down, with the subfolder in the config's cwd, id and name; a multi-module parent pom counts as one build. Spring Boot applications (@SpringBootApplication with main in a module that applies the Spring Boot plugin) get spring-boot configurations that build the module and run with its classpath. Gutter and file runs pick the build the file belongs to (also for Go modules), and only files outside any build run as single files; the main config lookup takes the nearest bootRun / run / spring-boot:run. On Windows, piped JVM (java, Maven, Gradle) and Python processes now write in the console encoding instead of the ANSI code page, so their output is no longer garbled. run_configs runs on a blocking thread.

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
