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.
- Runloop — Skip unless you specifically want its Devbox/Blueprint workflow — the highest per-hour rates captured here, with add-on fees on top.
