Fly.io pros
- +35+ regions, deploy multi-region with one command
- +Run any Docker image — no platform-specific buildpacks
- +Generous always-free tier (3 small machines)
Fly.io cons
- −Reliability has been bumpy across 2023–2025; status page tells the story
- −Support is community-first — paid support tiers exist but are light
- −Some primitives (volumes, secrets) have rough edges that bite production apps
Render pros
- +Predictable per-service pricing instead of mystery usage bills
- +Free tier for static sites and Postgres (with caveats)
- +Supports cron jobs, background workers, private services
Render cons
- −Free Postgres expires after 90 days unless upgraded
- −Cold starts on the free web service tier are very real
- −Free tier has been progressively trimmed since 2023; check current limits before betting on it
