Fit Notes
- Modal (Sandboxes) — Skip if pure sandbox price is the decision — you pay ~40% over E2B/Daytona for the same vCPU-hour; Modal earns it back only when the rest of your stack already lives on Modal functions.
- 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.
