How phpBB Compares to Competitors

Compared to hosted solutions like Discourse (starting around $100/month) or vBulletin (one-time license ~$249 plus hosting), phpBB offers a significant cost advantage by being entirely free. While competitors provide managed services, phpBB requires self-hosting and maintenance, shifting the cost burden to the user's infrastructure.
