Fly.io
- Egress is priced by destination region, from $0.02 per GB in North America and Europe to $0.12 per GB for Africa and India, so the same traffic costs six times more depending on where users are

- Volumes are billed on provisioned capacity rather than usage, at $0.15 per GB a month
- Reservation discounts of 40% require paying a year up front, from $36 to $1,440
- Fly Kubernetes is a separate $75 a month per cluster
- Dedicated IPv4 addresses are $2 a month each
Remix
- Different mental model than traditional React SPAs requires learning curve
- Smaller ecosystem compared to Next.js despite Shopify backing
- SSR adds server-side complexity for teams preferring client-first architecture
- Form-first approach not optimal for highly interactive UI-heavy applications
