outray 0.0.3

Python SDK for outray.dev tunneling service

Outray

outray is a Python library for creating HTTP, TCP, and UDP tunnels using https://outray.dev/. It allows you to forward local services to a remote endpoint easily.

Install via pip:

pip install outray

---

Features

• HTTP tunnel proxy (HttpListener)
• TCP tunnel proxy (TCPListener)
• UDP tunnel proxy (UDPListener)
• Forward a tunnel asynchronously or synchronously
• Built-in error handling and logging

---

Usage Example

• Asynchronous

import asyncio
from outray import forward, http

async def main():
    listener = http("http://localhost:8080")
    await forward(listener)

asyncio.run(main())

• Synchronous

import asyncio
from outray import forward, http

listener = http("http://localhost:8080")
forward_sync(listener)

---

API

## Environment Variables

Outray supports configuration via environment variables. These are optional but recommended.

### `OUTRAY_API_KEY`

Your API key used to authenticate tunnel connections.

```bash
export OUTRAY_API_KEY=your_api_key_here

If not provided explicitly, forward and forward_sync will automatically read this value from the environment.

Equivalent code usage:

await forward(l1)
await forward(l1, api_key="API_KEY")

---

OUTRAY_API_URI

The WebSocket endpoint used to establish tunnels.

export OUTRAY_API_URI=wss://api.outray.app

If not provided explicitly, this value is also read from the environment.

Equivalent code usage:

await forward(l1, api_key="API_KEY", ws_url="API_URL")

---

Creating a Listener

TCP

from outray import tcp

listener = tcp(local_host="localhost", local_port=8090, remote_port=20710)

UDP

from outray import udp

listener = udp(local_host="localhost", local_port=9000, remote_port=30710)

HTTP

from outray import http

listener = http(url="http://localhost:8080", subdomain="my-subdomain")

---

Forwarding a Tunnel

Asynchronous (forward)

from outray import forward
import asyncio

asyncio.run(forward(listener))

• forward(listener, ws_url=None, force_takeover=None, ping_interval=20, ping_timeout=20, api_key=None)
• Forwards the listener to the remote WebSocket tunnel.
• Handles reconnects automatically.

Synchronous (forward_sync)

from outray import forward_sync

forward_sync(listener)

• Same as forward but runs in a blocking synchronous context.
• Useful for scripts that do not use asyncio natively.

---

Logging

outray uses the standard Python logging module. To see detailed tunnel events:

import logging

logger = logging.getLogger("outray")
logger.setLevel(logging.DEBUG)
