## What it is
Waline is a self-hostable comment system for websites and blogs, consisting of a lightweight JavaScript client and a backend server deployable to Vercel, CloudBase, Railway, and many other platforms. It supports multiple databases (MySQL, PostgreSQL, SQLite, MongoDB, TiDB), full Markdown comments, social login, anti-spam and XSS protection, article reactions, and pageview counting.

## Use cases
- add a comment section to a static site or blog
- replace Disqus with a self-hosted comment system
- deploy a free comment backend on Vercel
- add pageview counters to blog posts
- let readers react to articles with emojis
- moderate comments with spam protection and email notifications

## When to choose
- you want a lightweight, privacy-friendly comment system with a real backend
- you need flexible deployment across many serverless platforms and databases
- you want Markdown, emoji, math, and HTML support in comments
- you need anonymous and social login commenting options

## When to avoid
- you need a fully serverless client-only solution without any backend
- you require deep integration with a specific CMS's native comment tables
- you want a plugin for an existing platform like WordPress rather than an embeddable widget
