WooCommerce
E-Commerce Platforms
WooCommerce itself is free and open source, and it plugs into WordPress, so you own the whole stack. The real bill is hosting that stays up through a sale, extensions that each need maintaining, and the time spent on updates, security patches and plugin conflicts.
Strengths
- No platform subscription — the plugin is free and open source
- Full control of the database, theme and checkout code
- Very large extension ecosystem
- You can host it anywhere, including cheap shared hosting to start
Trade-offs
- You are responsible for uptime, security patching and backups
- Extension costs accumulate and each one needs updating
- Checkout performance depends entirely on your hosting
- Plugin conflicts are a recurring source of bugs
