Fly Machines
Pros
- + ~300ms VM boot with automatic stop when idle — real scale-to-zero economics for request-driven workloads
- + Billed by the second with a fully published rate card; smallest Machine $2.19/30 days running
- + Low-level lifecycle control via REST API: create, start, stop, clone, update, destroy per VM
- + 17 regions on Fly's own hardware with per-Machine region placement
- + Fast restart from stopped state — assembled rootfs stays on the worker host
Cons
- - Fly.io-only API and infrastructure — no orchestration portability
- - Running the raw API means building your own scaling, placement retry and health logic
- - Always-on and idle costs accumulate: stopped rootfs $0.15/GB/month, volumes $0.15/GB/month, dedicated IPv4 $2/month
- - Capacity limits per region and host can make Machine placement fail
- - No free tier — only a 2-VM-hour/7-day trial — and no uptime SLA outside Enterprise plans
Northflank Containers
Pros
- + Per-second, usage-based pricing with published unit rates and no seat fees
- + Real free Sandbox: 2 services, 2 jobs, 1 database, up to $20/mo resources, always-on compute
- + BYOC runs the platform in your AWS/GCP/Azure/Oracle VPC while you keep your cloud commitments
- + Strong CI/CD: per-PR preview environments, stored builds with rollback, release pipelines
- + GPU workloads (L4/A100/H100), Jupyter, secure code execution, RWX volumes: AI-ready beyond typical PaaS
- + UI, CLI, API, and GitOps control surfaces with RBAC, secrets, and audit-oriented enterprise features
Cons
- - Young company (founded 2019, Series A): less operational track record than incumbents
- - Contractual SLA and 24/7 support are Enterprise-only
- - Storage, IOPS, throughput, egress, and gateway line items stack up on database-heavy architectures
- - Card/payment-method requirement for the free tier conflicts between the pricing page and billing docs
- - Deep platform abstraction means application-level lock-in even with BYOC
- - Documentation is thorough on features but thin on migration patterns and BYOC networking edge cases
