Closes #20328. ## Summary - Adds a CLI-side check that warns when `twenty-app-dev` is older than the latest published Docker Hub tag. - Reads `APP_VERSION` from the running container via `docker inspect` — no server endpoint, no version exposed publicly. (`APP_VERSION` is already baked in by `packages/twenty-docker/twenty/Dockerfile` for both `twenty` and `twenty-app-dev` targets.) - Fetches latest semver tag from Docker Hub (same API the admin panel already uses) and caches the result for 24h in `~/.twenty/version-check-cache.json`. - Wired into `twenty dev`, `twenty install`, and `twenty server start`. - Best-effort: silent on container-missing / docker / network errors, never blocks a command. ## Why CLI-side instead of a `/healthz` extension The original issue suggested comparing the running server version against Docker Hub. Exposing the running version on a public endpoint has a small but real security cost (helps attackers fingerprint vulnerable deployments), and the version is already inside the image — so the CLI can read it directly without ever calling the server. ## Test plan - [x] `nx run twenty-sdk:test` — added unit tests for `parseSemver` / `compareSemver` - [x] `nx run twenty-sdk:typecheck` - [x] `nx run twenty-sdk:lint` - [ ] Manual: with an old `twenty-app-dev` image running, run `yarn twenty install` → see warning - [ ] Manual: with an up-to-date image, run `yarn twenty dev` → no warning, cache file written - [ ] Manual: no container at all → no warning, no error

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty deploy
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
