Fit Notes

Northflank — Skip if you need agent-native session semantics (snapshot/pause-resume) — Northflank is general container platform pricing applied to long-running services and jobs, not a purpose-built agent sandbox SDK.
Fly Machines — Skip if you need a single per-vCPU+per-GiB price — Fly sells bundled presets that don’t decompose into our two-axis model; compare preset totals directly.
