Keyway — App Installer

Keyway installs an app from a single manifest — it downloads the parts, installs them, and runs setup. • Any format: APK, split APKs, XAPK, APKM, APKS, bundletool • Silent install with Shizuku or root, or the standard system installer • Picks the right splits for your device (ABI, density, language) • Open a file or a link to start; no account needed • Free — no ads, no purchases, no analytics

Keyway installs an Android app from a single manifest. Point it at a JSON5 file and Keyway downloads the APK parts, installs them — through the system installer, or silently when a privileged channel is available — and runs a declarative setup you can read in advance. One file describes the whole install. Keyway is free. No ads, no in-app purchases, no analytics, and no servers of its own. WHAT IT DOES • Installs from any SAI-family package: a plain APK, split APKs, .apks, .xapk, .apkm, .apkx, a .zip of splits, or bundletool output. • Picks the right config splits for your device (ABI, screen density, language) so nothing extra is installed. • Runs a declarative pre/post workflow the manifest defines — launch the app, grant a permission, open a settings screen, and more. • Shows a consent sheet first whenever a manifest declares one, so you always see the terms before anything installs. INSTALL METHODS • Auto — silent install when a privileged channel is available, otherwise the standard Android confirm dialog. • Privileged — require a privileged channel (never silently falls back). • System — always the platform installer with its confirm dialog. SILENT INSTALL, YOUR CHOICE Keyway installs silently through Shizuku (any compatible provider — Shizuku, Sui, Dhizuku, or a fork) or root. It binds to whatever privileged service you already run; it never ships one of its own, and it needs no special storage permission. SAFE BY DESIGN Because a manifest can come from any URL, what it is allowed to request is deliberately narrow: • Free-form shell, broadcast and start actions are disabled — a manifest can never run arbitrary privileged commands. • A manifest's requirements (privilege, backend, VPN) are checked before anything is downloaded; an install that can't succeed stops early. • Privileged steps with no privilege available are reported and skipped, never silently dropped. PRIVACY Keyway collects nothing. No account, no analytics, no advertising. The only network activity is fetching the manifest and the install parts you point it at.
