- Index format: fields are only added; an IDE reading a newer `format` still applies its revocations and `moved`, lists no plugins and asks to be updated, instead of failing to read the index. - Key continuity: an installed plugin updates silently only to a package signed with the same key, or a key it endorsed (`KeyEntry.endorsement`, `index --previous-key`, `openidea-plugin endorse`). Another signer, or an unsigned package replacing a signed one, is shown on the install page and needs the user's confirmation (`Consent.signerChange`). - Official key: release builds carry the official publisher's public key (`OPENIDEA_OFFICIAL_PLUGIN_KEYS`, derived from PLUGIN_SIGNING_KEY); `openidea.*` plugins must be signed with it or a key it endorsed, whatever the index lists. - Updates: the daily marketplace check announces new versions once, with Update All (also in the gear menu and as an action). An update that asks for nothing new installs with the grants the installed version has. - Index entries need `engine`; `categories` beyond the first three are ignored instead of rejecting the manifest.
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.
