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
