Fly.io
Pros
- + Fully published pricing for every billed resource, with worked example bills
- + Cheap always-on compute — $2.19/30 days for the smallest Machine in the cheapest regions
- + 17 regions on Fly's own hardware with Anycast routing and per-second billing
- + Strong ecosystem: Managed Postgres, Fly Kubernetes, Tigris S3-compatible object storage, Upstash extensions on one invoice
- + Concrete Enterprise SLA terms (99.9%, 15-minute urgent response) published openly
Cons
- - Free tier replaced by a tight trial (2 VM hours or 7 days)
- - Managed Postgres starts at $38/month — services are priced like a managed PaaS, not like the VMs
- - CLI-first workflow with real conceptual overhead (Machines, Apps, fly-replay, 6PN networking)
- - Uptime SLA only covers Enterprise plans; SLA downtime definition excludes hacking and virus attacks
- - Region count has shrunk from the widely quoted 35+ to 17, and prices vary by region
Cloudflare Pages
Pros
- + Unlimited sites, seats, requests and bandwidth even on the free tier
- + Preview deployment for every commit, unlimited previews on all plans
- + Pages Functions run on the Workers runtime with KV, D1, Durable Objects and R2 bindings
- + Builds and TLS are fully managed; zero server configuration
- + Flat plan pricing — delivery volume never changes the bill
Cons
- - Build limits (500/month Free) bind long before bandwidth does
- - 20,000-file and 25 MiB per-file ceilings push media-heavy sites to R2
- - Hard platform boundary: no persistent servers, no arbitrary runtimes
- - Shared build infrastructure can queue during peak periods
- - No uptime SLA below the Business plan
