# Fly.io Cost Tuning ## Overview Fly.io charges per-second for running machines plus storage. Key levers: auto-stop idle machines, suspend instead of stop, right-size VMs, and clean up unused volumes. ## Pricing Quick Reference | Resource | Free Tier | Cost | |----------|-----------|------| | shared-cpu-1x (256mb) | 3 VMs free | ~$1.94/month each | | shared-cpu-1x (512mb) | included | ~$3.88/month | | shared-cpu-2x (1gb) | - | ~$11.62/month | | Volumes | 3GB free | $0.15/GB/month | | Bandwidth | 100GB free | $0.02/GB after | | IPv4 | 1 free per org | $2/month each | ## Instructions ### Strategy 1: Auto-Stop Idle Machines ```toml # fly.toml — stop machines when no traffic [http_service] auto_stop_machines = "stop" # Full stop (cheapest, ~5s cold start) auto_start_machines = true min_machines_running = 0 # Allow all machines to stop # Use min_machines_running = 1 only for production apps ``` ### Strategy 2: Suspend for Faster Resume ```toml # Suspend keeps memory state — resumes in ~100ms but costs ~$0.50/month [http_service] auto_stop_machines = "suspend" ``` ### Strategy 3: Audit and Clean Up ```bash # List all apps and their machine counts fly apps list # Find idle/stopped machine

How do I install it?
Run `npx skills add jeremylongshore/claude-code-plugins-plus-skills --skill flyio-cost-tuning --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From jeremylongshore/claude-code-plugins-plus-skills, a repository with 2,630 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
