The paid concurrency baseline matches E2B Pro while removing its fixed monthly subscription.2
- CPU ($/vCPU-hour)
- 0.03528
- Monthly fee ($)
- 0
- Concurrent sandboxes (compared plan)
- 100
Daytona
Pool-based CPU and memory limits replace E2B’s instance-count quota for differently sized agents.6

- Tier 2 resource pool
- 100 vCPU / 200 GiB
Modal
CPU-heavy execution uses physical-core allocation instead of treating every sandbox as an identical E2B instance.4
- CPU ($/vCPU-hour)
- 0.070956

Original product baseline
E2B Pro adds $150/month to runtime charges; its 100 included concurrent sandboxes can expand to 1,100 through paid add-ons. Novita’s paid quota reaches the same 100 instances without that subscription.
Methodology and sources
Vercel publishes memory at $0.0212/GB-hour. For a common GiB basis, 1 GiB = 1.073741824 GB: the converted rate is $0.0227633/GiB-hour and 2 active vCPU + 4 GiB costs $0.34705/hour before plan fees.
Hourly examples assume 2 vCPU + 4 GiB allocated and continuously active for 1 hour, excluding storage, network, plan fees and credits. Modal physical cores count as 2 vCPU each at non-preemptible sandbox rates; Vercel uses its iad1 active-CPU rate at full utilization. Startup figures are vendor-reported and measure different events, so no fastest-start winner is assigned. Startup labels give a dated source’s year, or 2026 when an undated page was checked.
These E2B replacement costs are resource-charge estimates, not measured invoices. Novita AI publishes the comparison from the cited public documentation.
Alternatives to E2B are ordered by the 2 vCPU + 4 GiB continuously active hourly example, then by monthly plan fee; E2B and Daytona have equal compute rates. Concurrency counts, shared CPU pools and startup claims are not interchangeable ranking measures.
