Ruby gets an ERB editor mode (HTML with embedded Ruby), Ruby / Rake / RSpec run configuration types, and a Settings › Languages & Frameworks › Ruby page for choosing the interpreter (Auto picks the `.ruby-version` / mise / asdf install, else `ruby` on PATH). - Run: `.rb` scripts run from the editor context menu, `_spec.rb` / `_test.rb` files narrow an RSpec or Rake (`SPEC=` / `TEST=`) configuration, and Rakefile tasks are detected; Rake and RSpec go through `bundle exec` when the project has a Gemfile. The chosen interpreter's `ruby`, `bundle`, `rake` and `rspec` are used and its bin directory is put on PATH. - Configuration forms rebuild from a raw command line keeping option values with their options (`--format documentation`, `-I lib`), and a new Ruby configuration opens in the Ruby form with the script still to fill in. - External Libraries lists the Ruby standard library and the bundle's gems, including those Bundler installs inside the project (`vendor/bundle`). - Ruby is part of the frontend settings defaults and normalization, so the selected interpreter survives a settings round-trip.

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.
