Offline-first desktop apps in Rust and GPUI. Files stay in your folders; no account, no cloud service.

Download from office.elygpui.com or the latest release: Windows, macOS (Apple silicon and Intel) and Linux (AppImage, deb, rpm, Arch, Nix; Debian 11 and Ubuntu 20.04 or newer).

ElyMail needs a Microsoft client ID at build time: put ELY_MICROSOFT_CLIENT_ID=<id> in cred.txt at the repository root (git ignores it).

The scripts run on macOS, on Windows (LibreOffice under Cygwin, MuPDF with MSBuild) and on Linux inside packaging/linux/container.sh, an AlmaLinux 8 image that keeps the binaries on glibc 2.28.

Pushing a v* tag runs .github/workflows/release.yml. Self-hosted runners build macOS (arm64, and Intel under Rosetta), Windows and Linux with scripts/ci.sh and upload each app's packages, update manifests and the source archives to the GitHub release. macOS builds are signed and notarized.

cargo test --workspace; the script tests in tests/scripts (the window tests need macOS Accessibility permission; Linux tests run in containers); the benchmarks tests/perf/bench.py and tests/perf/folder-search.rs.
