The software is free either way. The important choice is who operates it.
Self-host when you have the skills and time
Your team controls the system and handles installation, monitoring, security updates, backups, restore tests, email delivery, and user support. This can be a good fit when those responsibilities already have clear owners.
Choose managed hosting when you want operating help
Managed plans provide a separately quoted service for defined user ranges. Confirm storage, backups, support, renewal, tax, and service terms before accepting a quotation.
Use the hosting decision guide, then visit Pricing for the current published options.
