## Why The `failing-app-installation-workspace-version` integration suite fails on CI (e.g. [this run](https://github.com/twentyhq/twenty/actions/runs/29105697459/job/86405891168)): ``` App requires Twenty server >=2.21.0 but this server is 2.20.0. subCode: SERVER_VERSION_INCOMPATIBLE ``` The test uploads an app requiring `>=${TWENTY_CURRENT_VERSION}` and expects the install to be rejected by the **workspace** version gate. But after the `2.21.0` version bump, `TWENTY_CURRENT_VERSION` (`2.21.0`) moved ahead of the latest instance upgrade command (`2-20`, so `getInferredVersion()` returns `2.20.0`). The tarball upload runs the **instance** server-compat check first, which rejects `>=2.21.0` against a `2.20.0` server before the workspace gate under test is ever reached. The sibling sync test is unaffected because sync only validates workspace compatibility, not the upload-time instance check. ## What Derive the required version range from the version the instance actually reached (the workspace upgrade cursor via `extractVersionFromCommandName`) instead of the drifting `TWENTY_CURRENT_VERSION` constant. This way: - The upload passes the instance server-compat check (server satisfies `>=<current version>`). - The workspace, which resolves one version behind after the injected failed cursor, still fails the workspace gate, producing the expected `WORKSPACE_VERSION_INCOMPATIBLE` error. The error assertion keeps using the normalized snapshot (`scrubSemverVersions`), so the concrete version numbers do not leak into the snapshot and future version bumps won't churn it. --- _Generated by [Claude Code](https://claude.ai/code/session_01XqhqQ8VGJZWBuznR8nRviX)_ <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22826?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

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.
