l0ng-ai 4fdbe9bac3 fix(editor): keep selections whole over line backgrounds and indent guides
Multi-line selections could show a 1px seam between their stacked
rectangles, indent guides showed as short dashes inside a selection,
and a breakpoint or execution line hid the selection past its text.

- Snap selection rectangle edges to device pixels so stacked pieces
  share one edge.
- Paint caret-row, breakpoint and execution line backgrounds on a
  pseudo-element below the selection layer.
- Draw indent guides on a pseudo-element above the text.

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.

Plugins

Plugins add actions, completion, quick fixes, tool windows, custom editors, themes, file icons and languages. They run as sandboxed WebAssembly components; themes, icon themes and languages need no code at all.

Install them from Settings › Plugins, or start your own with openidea-plugin new — see Writing OpenIDEA plugins and the official plugins. The plugin API is still a preview.
