Pricing Issues Reported by Users
Pricing surprises and unexpected charges
Users report difficulty predicting costs. One user's bill jumped 70% ($14 to $24) with no changes. Another reported $50-60/month for a low-traffic side project. Hidden costs include: dedicated IPv4 at $2/month per app, volumes charged whether used or not ($0.15/GB), and internal-only apps still consuming resources.
Aggressive billing with no alerts
Fly.io doesn't support billing alerts, so costs can spiral without warning. Free allowances don't cap your bill - you're automatically charged for overages. Users report receiving $25 unauthorized charges and attempted $747 charges. The complex per-second billing model makes budgeting nearly impossible.
Free tier confusion and removal
Fly.io no longer offers a general free tier for new organizations, though documentation still references it. Legacy users retained early allowances, causing confusion. Users signing up expecting free hosting are surprised by credit card requirements and daily reminder emails with no unsubscribe option.
