## Problem On workspaces with a sizeable AI chat history, the whole app was freezing during navigation, including Settings (one navigation click measured ~6.5s). ## Root cause `AgentChatProvider` is mounted app-wide in `AppRouterProviders`, so its effects run on every page. On every render it would: 1. auto-select the most recently active thread (`AgentChatThreadInitializationEffect`), 2. fetch that thread's **full message history** (`AgentChatMessagesFetchEffect`), 3. run `AgentChatStreamingPartsDiffSyncEffect` → `updateStreamingPartsWithDiff`, which loops over every message doing `isDeeplyEqual(existing, incoming)` + `structuredClone`. A large thread would produce multi-second freeze on every interaction, app-wide. (Confirmed via a Chrome CPU profile) ## Fix Don't run the agent-chat **message runtime** until the chat is actually opened. ## Note There is still room for improvement, opening AI chats would still be very slow.

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.
