From Zero to Production: Deploying Your AI SaaS

A comprehensive guide to deploying your Shipfastai app to Railway, Vercel, or AWS with zero downtime.

You've built your AI SaaS app with Shipfastai. Now it's time to deploy. This guide covers three popular deployment options and the trade-offs of each.

Option 1: Vercel + Railway (Recommended)

This is our recommended stack for most startups:

Frontend: Vercel (optimized for Next.js)

Backend: Railway (great for Python/FastAPI)

Database: Supabase (included)

Deploying to Vercel

# Install Vercel CLI

npm i -g vercel

# Deploy

vercel --prod

Configure environment variables in the Vercel dashboard:

NEXT_PUBLIC_SUPABASE_URL=your-url

NEXT_PUBLIC_SUPABASE_ANON_KEY=your-key

NEXT_PUBLIC_API_URL=https://your-railway-url

Deploying Backend to Railway

# Install Railway CLI

npm i -g @railway/cli

# Login and deploy

railway login

railway init

railway up

Option 2: AWS with Docker

For teams that need more control:

# Dockerfile

FROM python:3.11-slim

WORKDIR /app

COPY requirements.txt .

RUN pip install -r requirements.txt

COPY . .

CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]

Deploy to ECS or App Runner for managed container hosting.

Option 3: Self-hosted

For enterprise deployments, use Docker Compose:

version: '3.8'

services:

frontend:

build: ./frontend

ports:

- "3000:3000"

backend:

build: ./backend

ports:

- "8000:8000"

Zero-Downtime Deployments

Regardless of platform, follow these practices:

1. Health checks - Configure proper health endpoints

2. Graceful shutdown - Handle SIGTERM signals

3. Database migrations - Run before deploying new code

4. Feature flags - Roll out features gradually

Monitoring

Set up monitoring from day one:

Sentry for error tracking

PostHog for product analytics

Better Stack for uptime monitoring
