## What
Key-value storage for applications, as proposed in
twentyhq/core-team-issues#2391 — built on the existing `keyValuePair`
entity:
- Nullable `applicationId` relation on `keyValuePair` + a new
`APPLICATION_VARIABLE` type (fast instance command included)
- GraphQL CRUD on the metadata schema (`appKeyValue`, `setAppKeyValue`,
`deleteAppKeyValue`), requiring an `APPLICATION_ACCESS` token —
`applicationId` always comes from the token, never from arguments, so
apps can't touch each other's entries
- `kv.get` / `kv.set` / `kv.delete` helpers in
`twenty-sdk/logic-function`
## Scopes
- **`INSTALL`** (default): entries are private to one workspace install;
arbitrary JSON values
- **`GLOBAL`**: entries are shared across every install of the app, with
claim semantics — the value is always the claiming `workspaceId` and
only that workspace can overwrite or delete the key (guarded writes,
race-safe via insert-if-absent)
Since `applicationId` identifies an install (one row per workspace),
GLOBAL entries are stored under the registration owner workspace's
install so all installs of the same app share one namespace.
The GLOBAL scope is what enables cross-workspace webhook routing: e.g.
the Slack app's `serverRoute` resolver (running in the owner workspace)
can resolve `kv.get('slack:team:' + team_id, { scope: 'GLOBAL' })` to
find the workspace that connected that Slack team — without a workspace
being able to hijack another's mapping.
## Follow-ups
- Wire the Slack assistant PR (#22984) to write the claim at connect
time and read it in the events resolver
- `kv.*` access from front components

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.
