On macOS versions where WKWebView refuses user-installed fonts by family name (fonts in ~/Library/Fonts or /Library/Fonts), the editor, terminal, Markdown and UI fell back to the default font and Nerd Font icons showed as boxes; only a webfont loaded from the file's bytes renders. Root cause: the shared font resolver only ever referred to fonts by local family name, so every consumer depended on the WebView resolving user fonts by name. A URL-based webfont is blocked by the existing font-src policy, which stays unchanged. Fix: the shared resolver probes whether a family renders by name (on a document-attached canvas; a detached canvas falls back even when the font works) and only when it does not, fetches the enumerated user font files over a raw-bytes IPC (user fonts only, looked up by family, no paths accepted) and registers them with the FontFace API under a stable alias. Only the faces nearest regular/bold and their italics are loaded, once per family. Covers editor and editor fallback, diff/merge views, terminal font, fallback and built-in Nerd fallback (re-measured after loading), embedded terminal, settings preview, custom UI font, Markdown and Mermaid. A debug-only environment switch reproduces the WebView restriction for testing. Verified on macOS 26 with the restriction simulated (icons boxes before, correct after) and without it (no font bytes transferred, no regression). Not run on the reporter's macOS version, Windows or Linux; other platforms keep the previous behaviour. Fixes #592

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
Rust 1.96, Node 22, pnpm and the Tauri prerequisites.
Native notebook execution tests are opt-in and need two distinct Python environments
with ipykernel installed:
OPENIDEA_TEST_PYTHON=/first/env/bin/python \
OPENIDEA_TEST_PYTHON_SECOND=/second/env/bin/python \
cargo test -p ide-notebook --test kernel_runtime -- --ignored --test-threads=1
