Fit Notes
- E2B — Skip if your agents need long-lived environments — Hobby sessions die at 1h and Pro at 24h; this is for short-lived code-running sandboxes.
- 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.
