title: Server
description: Nutze den opencode-Server ueber HTTP.
---
import config from "../../../../config.mjs"
export const typesUrl = `${config.github}/blob/dev/packages/sdk/js/src/gen/types.gen.ts`
Der Befehl `opencode serve` startet einen headless HTTP-Server.
Er stellt einen OpenAPI-Endpunkt bereit, den ein opencode-Client nutzen kann.
---
### Nutzung
```bash
opencode serve [--port <number>] [--hostname <string>] [--cors <origin>]
```
#### Optionen
| Flag | Description | Default |
| --------------- | ----------------------------------- | ---------------- |
| `--port` | Port to listen on | `4096` |
| `--hostname` | Hostname to listen on | `127.0.0.1` |
| `--mdns` | Enable mDNS discovery | `false` |
| `--mdns-domain` | Custom domain name for mDNS service | `opencode.local` |
| `--cors` | Additional browser origins to allow | `[]` |
`--cors` kann mehrfach angegeben werden:
```bash
opencode serve --cors http://localhost:5173 --cors https://app.example.com
```
---
### Authentifizierung
Setze `OPENCODE_SERVER_PASSWORD`, um den Server mit HTTP Basic Auth zu schuetzen.
Der Benutzername ist standardmaessig `opencode`, kann aber mit `OPENCODE_SERVER_USERNAME` ueberschrieben werden. Das gilt fuer `opencode serve` und `opencode web`.
```bash
OPENCODE_SERVER_PASSWORD=your-password opencode serve
```
---
### Funktionsweise
Wenn du `opencode` startest, werden TUI und Server gestartet.
Die TUI ist dabei der Client, der mit dem Server spricht; dessen OpenAPI-3.1-Endpunkt dient auch zur Generierung des [SDK](/docs/sdk).
:::tip
Nutze den opencode-Server, um opencode programmatisch anzusteuern.
:::
Diese Architektur erlaubt mehrere Clients und programmatische Nutzung.
Mit `opencode serve` startest du einen eigenstaendigen Server.
Laeuft bereits eine TUI, startet `opencode serve` trotzdem eine neue Serverinstanz.
---
#### Mit bestehendem Server verbinden
Beim TUI-Start werden Port und Hostname zufaellig gewaehlt.
Alternativ gibst du `--hostname` und `--port` als [Flags](/docs/cli) vor und verbindest dich dann gezielt damit.
Der Endpunkt [`/tui`](#tui) kann die TUI ueber den Server steuern, etwa zum Vorbelegen oder Abschicken von Prompts.
Dieses Muster nutzen auch die OpenCode-[IDE](/docs/ide)-Plugins.
---
## Spec
Der Server veroeffentlicht eine OpenAPI-3.1-Spezifikation unter:
```
http://<hostname>:<port>/doc
```
Zum Beispiel `http://localhost:4096/doc`.
Nutze die Spec zum Generieren von Clients, zum Pruefen von Request/Response-Typen oder in einem Swagger-Explorer.
---
