Context7
Feeds AI the latest docs for libraries and frameworks before it answers, so code it writes does not use outdated, removed functions.
Description from the maker (original English)
Local, privacy-focused RAG service for code search via MCP. https://linggen.dev
These three are never merged into one score: opinions, measurements and popularity are different things.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

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/.
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.
One app, one launcher, several skills as tabs:
ling-mem daemonMac 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.
| Tag pattern | Where | What |
|---|---|---|
linggen-v | this repo | the macOS app tarball + .sha256 |
, no prefix | linggen/linggen | the ling engine binary, macOS and Linux |
v | linggen/linggen-memory | the ling-mem memory daemon |
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.
