## What it is
SCS is an HTTP session management library for Go that automatically loads and saves session data via middleware. It supports 19 server-side session stores (PostgreSQL, MySQL, Redis, SQLite, and more), multiple sessions per request, flash messages, token regeneration, and idle/absolute timeouts.

## Use cases
- manage user login sessions in a Go web app
- store session data in Redis or PostgreSQL
- implement remember me functionality
- add flash messages after redirects
- regenerate session tokens to prevent fixation attacks
- handle multiple sessions per request
- replace gorilla/sessions with a faster alternative

## When to choose
- you are building Go web applications or APIs needing server-side sessions
- you want OWASP-aligned session handling with timeouts and token regeneration
- you need pluggable session stores across many databases
- performance and low memory usage matter

## When to avoid
- you need client-side (cookie-encrypted) session storage
- you are not using Go
- you need a full authentication framework with user registration and OAuth

## Facets
- artifact type: library
- maturity: stable
- function: middleware, auth, http-server, caching
- domain: web-development, backend, security, developer-tools
