## What it is
Pay is a payments engine (Rails engine gem) for Ruby on Rails 6.0+ that standardizes integration with payment processors like Stripe, Braintree, Paddle, and Lemon Squeezy. It provides models and APIs for customers, payment methods, charges, subscriptions, and webhook handling.

## Use cases
- add stripe subscriptions to a rails app
- handle recurring billing and payments in ruby on rails
- manage customer payment methods across multiple processors
- process one-time charges with stripe or braintree
- handle payment webhooks in rails
- support sca-compliant checkout for european customers
- switch payment providers without rewriting billing code

## When to choose
- you're building a rails app that needs subscriptions or one-time payments
- you want a unified api over stripe, braintree, paddle, or lemon squeezy
- you need sca-compliant payments and webhook handling out of the box

## When to avoid
- you're not using ruby on rails
- you need highly complex, provider-specific payment flows
- you need marketplace features beyond basic stripe connect support

## Facets
- artifact type: library
- maturity: active
- function: sdk, webhook, middleware
- domain: fintech, e-commerce, web-development, backend
- platform: ruby, self-hosted
