OpenIDEA

What it does
A desktop program for writing code that follows the habits of IntelliJ IDEA: the same keyboard shortcuts, the same tool windows and the same search-everywhere. It includes an editor with code completion, a debugger, Git, a terminal and built-in database and HTTP clients, and says it covers more than 60 languages. Ready installers exist for Windows, macOS and Linux and nothing else needs installing. It is for programmers, is free under Apache 2.0, and is still at version 0.1, about two weeks old.

Risk signals (3)
- Infovery early version of a big program
The repository was created on 2026-10-21 and is already at version 0.1.33 after 29 releases in under two weeks (Cargo.toml: version = "0.1.33"), with 133 open issues. A full programming workspace at version 0.1 is likely to still have gaps.
AI review
- Infospeed comparison measured by the project
The README's table showing 1.1 s to be ready and 169 MB of memory against 13.2 s and 2011 MB for IntelliJ IDEA was measured by the project itself on one PC ("Windows 11, 32-core AMD, 62 GB RAM"), and it notes "IDEA analyses Python more deeply, so 'ready' doesn't mean the same work on both sides".
AI review
- Infocopies the look of a paid product
The project describes itself as "The IDE you know, rebuilt in Rust" with an "IntelliJ IDEA-style keymap" and even a script to import IntelliJ themes (`theme:import-intellij`), while stating "Not affiliated with JetBrains. IntelliJ IDEA is a trademark of JetBrains s.r.o."

What Radar could not check
- Whether the Windows and macOS installers are signed by the publisher, since the project says nothing about it.
- Whether the speed and memory numbers hold on an ordinary computer and on your own projects.
- How complete the code understanding really is for each of the 60+ languages at this early version.
- Whether the debugger, database and HTTP tools work for your setup.
- How much disk space it uses after it indexes a large project, beyond the installer size.
