# Ports & prereqs

> Ports and tool versions for RAGSuite native and Docker installs.

Requirements match the official Platform Manager CLI ([`@ragsuite/ragsuite`](https://www.npmjs.com/package/@ragsuite/ragsuite)).

## Ports

| Service  | Native          | Docker           |
| -------- | --------------- | ---------------- |
| API      | **9090**        | **9090**         |
| Web      | **9191** (Expo) | **9191** (nginx) |
| Postgres | **5436**        | **5436**         |
| Redis    | **6382**        | **6382**         |
| Chroma   | **8004**        | internal         |

OpenAPI when the API is up: [http://localhost:9090/docs](http://localhost:9090/docs)

<Warning>
  If another service already binds **9090**, **9191**, **5436**, **6382**, or **8004**, `ragsuite start` and `ragsuite doctor` will fail until you free those ports or change the conflicting service. Do not guess alternate ports unless you also update `.env` consistently.
</Warning>
