What is SwapLayer?

SwapLayer is a unified infrastructure layer for Django that protects you from vendor lock-in.

Instead of coupling your code directly to Stripe, AWS, or Twilio, you write against one consistent interface and swap providers by changing a single configuration line.

The Problem

# ❌ Tightly coupled - if Stripe fails, you rewrite everything
import stripe
customer = stripe.Customer.create(email='[e-mail]')

The Solution

# ✅ Provider-agnostic - swap providers in settings
from swap_layer import get_provider
payments = get_provider('payments')
customer = payments.create_customer(email='[e-mail]')

---

Quick Start

1. Install

SwapLayer has optional dependencies - install only what you need:

# Install with specific providers
pip install swaplayer[stripe]        # Just Stripe billing
pip install swaplayer[identity]      # Just WorkOS/Auth0
pip install swaplayer[email,sms]     # Email + SMS

# Or install everything
pip install swaplayer[all]

Available extras:

• stripe - Stripe payment processing
• identity - WorkOS/Auth0 OAuth/SSO
• email - Enhanced email (django-anymail)
• sms - Twilio/AWS SNS messaging
• aws - AWS services (S3, SNS)
• mcp - AI assistant integration
• all - Everything

2. Configure

# settings.py
from swap_layer.settings import SwapLayerSettings

SWAPLAYER = SwapLayerSettings(
    email={'provider': 'django'},
    payments={'provider': 'stripe', 'stripe': {'secret_key': '...'}},
    sms={'provider': 'twilio', 'twilio': {'account_sid': '...'}},
    storage={'provider': 'django'},
)

3. Use Anywhere

from swap_layer import get_provider

# Email
get_provider('email').send(to='[e-mail]', subject='Hello')

# Payments  
get_provider('payments').create_customer(email='[e-mail]')

# SMS
get_provider('sms').send(to='+1555555', message='Welcome!')
