### About Chat Agent by Trigger.dev

Chat Agent is a backend for AI chat applications that runs each conversation on its own dedicated machine. It is part of Trigger.dev, a platform for building and running AI agents and workflows in TypeScript. The tool handles long-running tasks, survives browser refreshes, and lets you close the tab without losing state.

### Review

Chat Agent was launched this week. It aims to replace the standard request/response endpoint with a machine that persists for the whole conversation. The makers report it has been in production since June, including at Arena.ai, handling millions of sessions.

#### Key Features

- Every conversation gets its own machine; the machine sleeps when nobody is typing and wakes where it left off.
- No timeouts in long-running turns. The makers' production data shows 1 in 20 turns runs longer than 36 minutes.
- Streaming survives a page refresh or a closed tab; picking up later returns the stream mid-response.
- Memory between turns uses variables. A sub-agent created four questions ago remains available the next day.
- Built-in tracing for prompts, tool calls, latency, and cost per turn with no extra setup.

#### Pricing and Value

Chat Agent runs on Trigger.dev, which is open source under Apache 2.0 and can be self-hosted. The reference content does not define a specific pricing model for Chat Agent separate from the Trigger.dev platform. Waiting for a human approval overnight is not billed for the wait time.

#### Pros

- Works with the AI SDK you already use: streamText on the server, useChat on the client.
- No need to manage external state such as Postgres or Redis for conversation memory.
- The underlying platform, Trigger.dev, has been reviewed positively for developer-speed, scalability, and responsive support.
- Open source and self-hostable under Apache 2.0.

#### Cons

- The documentation and setup assume familiarity with TypeScript and Trigger.dev's existing workflow system.
- Pricing for Chat Agent specifically is not yet defined, which creates uncertainty for budget planning.
- Not well suited for teams that need a GUI-driven chat builder rather than a code-based integration.

Chat Agent suits developers who already use the AI SDK and want to avoid building hand-coded durable chat infrastructure with workaround timeouts and external state. Teams comfortable with TypeScript and comfortable with self-hosting or the Trigger.dev platform will find a fitting tool. Non-technical users or those preferring a visual interface should look elsewhere.
