Linggen Releases

Public download host for the Linggen macOS app.

Linggen is a local AI app engine — the core runtime (engine source) hosts skills as full-featured native apps. The app bundles the engine and its skills into one .app, served from a local daemon (http://127.0.0.1:9527) with all state under ~/.linggen/.

Install

curl -fsSL https://linggen.dev/install-app.sh | bash

Curl rather than a browser download on purpose: macOS attaches a quarantine attribute to anything a browser fetches, and these builds are ad-hoc signed rather than notarized, so a downloaded copy would be blocked on first launch. The installer fetches the tarball, checks its sha256, and puts Linggen.app in /Applications.

On first launch the app starts the bundled ling engine on 127.0.0.1:9527, or reuses a healthy daemon already listening there. The daemon shuts itself down after 5 minutes idle. Updates arrive through the app's own updater.

What's in it

One app, one launcher, several skills as tabs:

• Mac Shifu — macOS health: disk, apps, caches, plus iPhone/Mac photo and video cleanup
• CFO — personal finances: imports bank and credit exports, builds spend reports, learns your categories
• DJ — vibe to tracklist to a tagged library, synced to your phone
• Memory — durable cross-host memory on the ling-mem daemon

Mac Shifu (formerly Sys Doctor) and CFO were once separate downloads. They are skills inside the one app now, and linggen.dev/install-sys-doctor.sh and install-cfo.sh redirect here.

Releases

Only the app is hosted here. It bundles its own copy of the engine, so the app version and the engine version move independently.

Builds are macOS arm64, ad-hoc signed, not notarized. The app source lives in linggen/linggen-app (private); the engine, the skills, and the memory daemon are public.
