While standard hosting and database infrastructure have predictable costs, please note that operating this app also relies on Cloudflare R2 (for media storage) and Firebase (for push notifications). Both platforms offer generous free tiers suitable for starting out, but exceeding their free limits as your user base scales will result in additional usage-based costs. Standard third-party payment processing fees also apply.

• Cloudflare R2 account
• Firebase project (FCM/APNs)
