## Why App installability can silently regress from two directions, and today CI only covers one of them: 1. A **server** change (about to merge from the monorepo) breaks the ability to install the **current public apps** — a backward-compatibility regression users would hit on upgrade. 2. An **app** change breaks against a server **built from the current monorepo files** (not just the last published image), so the app and the upcoming server drift apart before either ships. Both are compatibility guarantees between the server and the app catalog. Today they are only tested from the app side, against the latest published image. This PR makes CI enforce the contract from both sides: - Any server PR must keep **every** current public app installable. - Any app PR is exercised against both the **released** server (its integration suite — what users run today) and the **upcoming** (monorepo) server (integration plus deploy + install). ## What Shared building blocks so both CIs exercise the same paths instead of duplicating them: - **`spawn-twenty-server`** (composite action) — returns a running server (`server-url` + `api-key`) from either the latest published Docker Hub image or a server built from the monorepo. Both sources expose the same contract, so callers never branch on how the server came up. - **`test-twenty-app`** (composite action) — exercises one app against a given server, delegating deploy + install to the shared `deploy-twenty-app` / `install-twenty-app` actions. - **`discover-apps`** (reusable workflow) — the single source of truth for the app matrix. Parameterized by `scope` (`public` vs `internal-and-public`) and `changed-only`, so both CIs derive their matrix from the filesystem instead of a hand-maintained list. Discovery stays automatic: a newly added public app is picked up with no CI edit, which is what keeps the "every public app" guarantee honest. Wired in: - **CI Server** gains a `server-apps-install-smoke` matrix that installs every public app (`discover-apps` with `scope: public, changed-only: false`) against the about-to-merge server, gated in `ci-server-status-check` so a regression blocks merge. - **CI Twenty Apps** discovers changed apps (`scope: internal-and-public, changed-only: true`) and runs each against both server sources — the released image and the monorepo build. ## Why the coverage differs per side (not "always everything") `test-twenty-app` has three explicit modes — `installation-and-integration-test` (integration + deploy + install), `integration-test-only` (suite only), `installation-only` (deploy + install only) — because the useful signal depends on what actually changed: - **App PR against the monorepo server → `installation-and-integration-test`.** The app changed, so run its whole suite against the upcoming server, install included. - **App PR against the released server → `integration-test-only`.** Checks the app's own suite against what users run today; install against the released image is left to the SDK e2e path. - **Server PR → `installation-only`, across all apps.** The apps did not change; the only question is "can each one still be installed." Running every app's full integration suite on every server PR would be far slower and largely redundant. Installation-only keeps this broad (the whole catalog) and cheap enough to always run and block merge. The tradeoff is deliberate: broad but shallow where nothing in the app changed, deep where it did. ## Notes / trade-offs - On app-only PRs the `local` source pays a full server build per app (the `server-build` cache is only warm on server PRs). Could be optimized later with a shared warm-up job. - SDK-local (Verdaccio) install testing stays in `ci-create-app-e2e-minimal`; this PR's `local` source targets the server build. <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22636?utm_source=github" rel="nofollow noreferrer noopener" target="_blank">``<img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg">``</a>

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

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 app:publish --private
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.
