## Context When an installed application misbehaves (e.g. a logic function loop DDoSing the server or the database), we currently have no targeted way to shut it down in production: the only kill switch is `LOGIC_FUNCTION_TYPE=DISABLED`, which disables logic functions for the whole instance. This PR adds an emergency stop mechanism at two levels: - **Workspace level**: stop one installed application in its workspace. - **Server level**: stop every application installed from an `applicationRegistration`, across all workspaces. ## How it works **New nullable `stoppedAt` columns** on `core.application` and `core.applicationRegistration` (fast instance command `2.24.0`, with `up`/`down` and `@WasIntroducedInUpgrade` decorators on the entities). **Enforcement in a single choke point**: `LogicFunctionExecutorService.execute()` is the funnel behind every execution path (public route triggers, server route triggers, cron triggers, database event triggers, workflow actions, agent tool calls, manual GraphQL execution, install hooks). A new `assertApplicationNotStopped` guard runs right after the flat entities are resolved and throws `LOGIC_FUNCTION_DISABLED` (already mapped to a 403 on route triggers and handled by the GraphQL exception handler) when: - `flatApplication.stoppedAt` is set (workspace-level stop, read from the cached flat application maps: zero extra runtime cost), or - the linked registration is stopped (one indexed PK lookup, same pattern as the existing per-execution server-variable query). **Propagation**: the workspace-level stop invalidates and recomputes `flatApplicationMaps` for the workspace, so all server instances pick the flag up within the local cache TTL (100ms). The registration-level flag is read live, so it is effective immediately. ## Ops commands ```bash # Workspace level yarn command:prod application:stop -a <application-id> yarn command:prod application:start -a <application-id> # Server level (all applications of the registration, all workspaces) yarn command:prod application-registration:stop -r <application-registration-id> yarn command:prod application-registration:start -r <application-registration-id> ``` Each command logs what was stopped/started and, for registrations, how many installed applications are affected. ## Notes - Stopped executions fail fast at the guard, so queued trigger jobs (cron/db-event) burn a negligible amount of work while stopped. - The two flags are independent: lifting a registration-level stop does not clear workspace-level stops that were set individually, and vice versa. - Unit tests added for `ApplicationStopService`. --- _Generated by [Claude Code](https://claude.ai/code/session_01CjEnKUACn89aSgK1wEMH2d)_ <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/23183?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.
