Cap has shipped as the GPUI app since 0.6.1. This removes the Tauri app (apps/desktop) and everything that only existed for it, so apps/desktop-gpui is the one desktop app in the repository. The Tauri source stays browsable at cap-v0.6.2.

Loading

The GPUI app owns its inputs

The GPUI build and bundle read a lot straight out of apps/desktop. Those files move with git mv (byte-identical) to where the bundle already places them:

From	To
src-tauri/icons/{32x32,128x128,128x128@2x,icon,Square310x310Logo}.*, icons/macos/icon.icns	apps/desktop-gpui/icons/
src-tauri/icons/tray-default-icon.png	apps/desktop-gpui/assets/tray/
src-tauri/sounds/*.ogg	apps/desktop-gpui/assets/sounds/
src-tauri/assets/backgrounds/**, src/assets/music/*.mp3	apps/desktop-gpui/assets/{backgrounds,music}/ (same relative paths the bundle uses)
src/assets/tears-and-fireflies-adi-goldstein.mp3, packages/ui-solid/icons/cursor-{macos,windows}.svg	apps/desktop-gpui/assets/onboarding/
src-tauri/Entitlements.plist, assets/dmg-background.png	apps/desktop-gpui/packaging/macos/
src-tauri/assets/nsis-{header,sidebar}.bmp	apps/desktop-gpui/packaging/windows/
src-tauri/test-data/clip-thumbnail-*.mp4	apps/desktop-gpui/tests/data/
src-tauri/src/recording_start_sound.rs (was #[path]-included)	apps/desktop-gpui/src/app_sounds/recording_start_sound.rs
src-tauri/binaries/ (sidecar staging)	apps/desktop-gpui/binaries/

• apps/desktop-gpui/tauri.conf.json, build.rs, include_bytes! sites and the dev fallbacks in editor_sidebar.rs / editor_audio.rs point at the new paths; nothing in the GPUI app reaches into apps/desktop any more.
• The Tauri CLI is still the packager. It moves to apps/desktop-gpui/package.json, which takes over the @cap/desktop workspace name, so bun run tauri bundle / tauri signer sign run from the app's own directory (scripts/bundle-gpui.mjs, scripts/build-macos-packages.mjs, scripts/finalize-linux-appimage.mjs).
• scripts/bundle-gpui.test.mjs now pins the shipped identity (bundle id, updater pubkey and endpoint, cap-desktop deep link) as literals instead of comparing against the deleted Tauri configs.

Removed

• apps/desktop, packages/ui-solid, vendor/tao, vendor/tauri-nspanel, the stray apps/src/utils/tauri.ts.
• Root workspace member, tauri workspace dependency, and the tao / tauri-nspanel patches (Cargo.toml). Cargo.lock only loses the 212 packages nothing else uses; no version changes.
• Tauri-only tooling: scripts/check-tauri-plugin-versions*, scripts/run-gpui-build*, scripts/verify-gpui-release-inputs.mjs, the tauri:build, check-tauri-versions and test:desktop:memory* scripts, the CI tauri-plugins job, the apps/desktop resource path filter, and --exclude cap-desktop in clippy.
• build-gpui-binary.sh no longer stages cap-gpui-<target> as a Tauri sidecar; bundle-gpui.mjs stages the main binary itself as before.
• scripts/linux-bundle-config.mjs drops the Tauri defaults (WebKitGTK RPM deps, GStreamer media framework). The generated apps/desktop-gpui/tauri.linux.conf.json is byte-identical to the one main writes.
• Unused Tauri v1 dev dependencies in packages/ui.

Dev-only switch back to the Tauri app

Debug builds had a Settings > Experimental > Developer toggle that quit the GPUI app and asked scripts/dev-desktop.mjs to restart tauri dev, plus a hand-off marker file and a dev.sh gate that skipped launching while "the classic app owns the session". All of it goes (settings_pages.rs, settings_window.rs, store.rs, main.rs, the 17 strings in every locale, dev.sh). Release builds never showed it.

bun run dev:desktop now runs cap-setup, prepares the patched gpui checkout, then:

// scripts/dev-desktop.mjs
process.platform === "darwin"
	? spawn("bash", [path.join(gpuiDir, "dev.sh")], { cwd: gpuiDir, stdio: "inherit" })
	: spawn("cargo", ["run"], { cwd: gpuiDir, stdio: "inherit", env: runtimeEnvironment(process.env) });

On Windows and Linux, runtimeEnvironment puts the root target/ FFmpeg / ONNX Runtime libraries on PATH / LD_LIBRARY_PATH, matching what CI's GPUI test job does.

Releases

• apps/desktop-gpui/Cargo.toml is the version source. sync-desktop-versions.mjs keeps the CLI in step with it, and publish.yml, publish-nightly.yml and build-linux-packages.mjs read it.
• promote-nightly can rebuild a nightly commit from before this change with the new workflow, so desktop-release.yml also stamps apps/desktop/src-tauri/Cargo.toml when it exists, and the Windows updater re-sign step uses whichever directory holds the Tauri CLI.

Deliberately unchanged

• crates/workspace-hack. Regenerating it after dropping the Tauri crate would also drop features Tauri had been unifying into the shipped binaries: reqwest's rustls, cookies and macOS proxy features and ort's download-binaries in the CLI, objc2's exception handling, and objc2's disable-encoding-assertions in the GPUI app. That is a behavior change for shipped artifacts and belongs in its own PR. Only the two tauri entries that would make cargo hakari error are removed from .config/hakari.toml. The cap CLI and cap-muxer feature trees match main on all four release targets, and the GPUI lockfile is untouched.
• 0.6.0 compatibility. The store file format, so.cap.desktop identifier, cap-desktop scheme, updater key and endpoint, the web /api/releases/tauri and desktop API routes, and the "last Tauri version" download page all stay.
• GPUI source comments that cite Tauri files (*.tsx, apps/desktop/...) as the 1:1 parity source stay as written; apps/desktop-gpui/README.md explains they point at cap-v0.6.2. Historical findings logs (crates/editor/PLAYBACK-FINDINGS.md, crates/export/EXPORT-FINDINGS.md, capcodec/) are left as records of past work.

Heads up

• CAP_LOGO_URL (transactional emails) and the README logo now load apps/desktop-gpui/icons/Square310x310Logo.png from raw GitHub. Emails sent before this merges reference the old path, which stops resolving once it lands.
• Local checkouts keep untracked build output under apps/desktop/ (node_modules, src-tauri/target); it can be deleted by hand.

Docs (README.md, CONTRIBUTING.md, AGENTS.md, apps/desktop-gpui/README.md, packaging/linux/README.md) describe the GPUI-only layout, the dev flow per platform, and where recordings live in development builds.

Confidence Score: 5/5

The changes since the last review appear safe to merge.

Summary

Removes the old Tauri app and makes apps/desktop-gpui the only desktop app.

• The GPUI app builds and bundles from assets in its own app tree.
• The old Tauri desktop app and its app-only workspace pieces leave the repository.
• Desktop development starts GPUI directly, without a switch back to Tauri.
• Desktop packaging and release jobs use the GPUI app as their source.
