In-Depth Analysis
Fly.io
Deploy apps close to users on edge infrastructure
Fly.io abandoned fixed plans in favor of pure pay-as-you-go, which is transparent but makes cost prediction harder.
Watch out
Bandwidth is not free and varies wildly by region: $0.02/GB in North America/Europe but $0.12/GB in Africa and India. An app serving 100GB/month to African users costs $12/month in bandwidth alone, 6x the North American rate
Strengths
- +Run apps close to users globally
- +Excellent for containerized apps
- +Free allowance included
- +Good CLI experience
- +Sqlite and Postgres hosting
Weaknesses
- -Learning curve for full features
- -Pricing model complex
- -Support can be slow
- -UI less polished
- -Debugging remote apps hard
Key features
Cloudflare Workers
Run serverless JS/Wasm at the edge with instant cold starts
Cloudflare Workers at $5/month is among the cheapest serverless entry points, and the free tier (100K requests/day) is genuinely generous for prototyping.
Watch out
CPU time is the real billing dimension, not requests. The included 30M CPU-ms sounds generous, but a single image-processing Worker using 50ms CPU per request exhausts it after just 600K requests/month, well under the 10M request allowance
Strengths
- +Global edge network
- +Great free tier
- +Low latency
Weaknesses
- -Limited runtime
- -Different programming model
