Docker sandboxes for AI agents
Choose Docker Sandbox for a $0 local software fee, E2B for a $0 Hobby platform fee and 20 concurrent sandboxes, or Daytona for a 100 vCPU Tier 2 pool after a $25 top-up. Novita AI has the lowest managed compute rate: $0.11664 per 2 vCPU / 4 GiB hour.
| Need | Pick | Why |
|---|---|---|
| Local execution without a cloud compute charge | Docker Sandbox | $0 software fee; local host resources are funded separately.1 |
| No monthly platform fee | E2B | Hobby has a $0 platform fee and 20 concurrent sandboxes.2 |
| Larger Tier 2 resource pool | Daytona | Tier 2 provides 100 vCPU, 200 GiB RAM and 300 GiB storage after a $25 top-up.6 |
| Lowest managed compute rate | Novita AI | $0.11664 per 2 vCPU / 4 GiB hour, 29.6% below E2B and Daytona at $0.1656.923 |

Options, strengths and limitations
Novita AI
Novita Agent Sandbox bills allocated vCPU and memory per second; the first 60 GB of storage is included.9
- Compute / runtime hour
- $0.11664
- Example quantity
- 100
- Example total
- $11.664
Strengths
- Lowest managed rate in this example: $0.0000098/vCPU-second plus $0.0000032/GiB-second; the paid tier allows 100 concurrent sandboxes and 24-hour sessions.9
Limitations
- The free tier allows 5 concurrent sandboxes and 1-hour sessions; paid limits apply after a balance top-up. The <200 ms launch figure is vendor-reported.9

E2B
E2B Hobby allows 20 concurrent managed sandboxes.
- Compute / runtime hour
- $0.1656
- Example quantity
- 100
- Example total
- $16.56
Strengths
- Hobby has a $0 platform fee and 20 concurrent sandboxes.2
Limitations
- Hobby sessions stop at 1 hour; 24-hour Pro sessions add $150/month before compute.2
Sources:2
Daytona
Daytona Tier 2 pools 100 vCPU across running sandboxes.6
- Compute / runtime hour
- $0.1656
- Example quantity
- 100
- Example total
- $16.56
Strengths
- Tier 2 provides 100 vCPU, 200 GiB RAM and 300 GiB storage after a $25 top-up.6
Limitations
- Tier 2 needs a $25 top-up; its 100 vCPU allowance is pooled, not per sandbox. A linked credit card is required.6
Sources:3
Modal
Modal connects Python-defined images to Sandbox execution with a 24-hour maximum lifetime; compare its workflow with E2B.7
- Compute / runtime hour
- $0.23796
- Example quantity
- 100
- Example total
- $23.796
Strengths
- Sandbox timeout can be configured up to 24 hours.7
Limitations
- Sandbox rates are $0.00003942/physical-core-second plus $0.00000667/GiB-second.4
Sources:4
Vercel Sandbox
Vercel bills active CPU and provisioned memory separately.
- Compute / runtime hour
- $0.3408
- Example quantity
- 100
- Example total
- $34.08
Strengths
- iad1 bills CPU at $0.128/hour and memory at $0.0212/GB-hour.5
Limitations
- Hobby lasts up to 45 minutes; Pro up to 24 hours. Memory remains billable during I/O waits.5

Methodology and sources
Docker Sandbox / Novita AI / E2B / Daytona / Modal / Vercel Sandbox. Compute uses 100 total runtime hours, 2 vCPU and 4 GiB nominal memory, with 100% active CPU, before credits and monthly platform fees. Storage, egress and creation charges are excluded. Modal uses Sandbox non-preemptible rates; its physical core is equivalent to 2 vCPU. Vercel publishes GB rather than GiB and bills active CPU; its 4 GB configuration is not byte-identical memory. Daytona’s <90 ms creation figure is vendor-reported in 2026 and is not a matched cross-vendor benchmark. Docker’s local software has no metered host price here and is excluded from the cloud compute cost ranking. Runtime allocation, plan-specific concurrency and lifetime are provider conditions, not a common startup-time column. Published timing statements use different events and do not establish a cross-vendor latency ranking. Novita AI uses its published per-second vCPU and memory rates; its <200 ms average launch is vendor-reported in 2026 and is not a matched benchmark.
