Why

You prototyped something in a notebook. Now you want to share it. Alph gives every project a public URL — start a web server and it’s live.

​
Quick Start

  1. Start your app on port 5000, bound to 0.0.0.0
  2. It’s live at https://{org}-{project}.runalph.dev
That’s it. No Docker, no deploy commands, no config files.

​
Framework Examples

​
Streamlit

# app.py
import streamlit as st
st.title('My Dashboard')
st.write('Hello from Alph!')

streamlit run app.py --server.port 5000

​
Gradio

import gradio as gr

def greet(name):
    return f"Hello {name}!"

demo = gr.Interface(fn=greet, inputs="text", outputs="text")
demo.launch(server_port=5000, server_name="0.0.0.0")

​
FastAPI

from fastapi import FastAPI
import uvicorn

app = FastAPI()

@app.get("/")
def read_root():
    return {"message": "Hello from Alph!"}

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=5000)

​
Keep It Running

# tmux (recommended)
tmux new -s webapp
python app.py
# Detach: Ctrl+B, then D

# Or nohup
nohup python app.py > app.log 2>&1 &

​
Custom Domains

Serve from your own domain instead of runalph.dev:
  1. Go to Settings > Domains in your project
  2. Add your domain (e.g., app.example.com)
  3. Create a CNAME record pointing to the tunnel hostname shown
  4. Click Verify — SSL is provisioned automatically
Works with subdomains and apex domains (if your DNS provider supports CNAME flattening).
