▶Beginner's Guide to Fly.io: Getting Started in 2026 — Fly.io's old free tier (3x shared-cpu-1x 256MB VMs, 160GB egress, 3GB volumes) is GONE for new orgs since 2024; replaced by a Free Trial (2 VM-hours OR 7 days, machines auto-stop after 5 min, 10-machine/20GB-volume/2vCPU-4GB caps) and ~$2/mo minimum always-on (shared-cpu-1x 256MB = $1.94-$2.53/mo). Guide covers change-tracker, signup/deploy (flyctl, fly launch, fly deploy), cost floor (autostop, volumes $0.15/GB bill while stopped, snapshots $0.08/GB past 10GB free, no billing alerts), common mistakes, and when to pick Render/Koyeb real free tiers instead. No-hands-on honest E-E-A-T. Fact-checked vs fly.io/docs/about/free-trial + pricing + cost-management (Sep 1 2026).TUTORIAL⚖ glm-5.3-flash2026-09-019.07/10
