Overview

Splox Sandbox provides secure, isolated development environments for code execution, testing, and rapid prototyping. With flexible compute resources and pre-configured templates, Sandbox enables safe experimentation without infrastructure setup.

Why Use Sandbox?

  • Isolated environments - Secure, sandboxed execution
  • Flexible compute - Scale vCPUs and memory as needed
  • Pre-configured templates - MCP, VS Code, NextJS, React, Browser
  • Pay-per-second - Only pay for actual usage time
  • Free storage - No additional cost for file storage
  • AI integration - Works seamlessly with Splox workflows

​
Pricing Model

Pay only for the compute resources you use, billed per second.

StorageFREEPersistent file storage
Example: A sandbox with 4 vCPUs and 8GB RAM costs:
  • (4 × 0.0000364)+(8×0.0000364) + (8 × 0.000013) = $0.0002496/sec
  • 1 minute = $0.015
  • 1 hour = $0.90
Cost optimization: Stop sandboxes when not in use!

​
Best Practices

Optimize Costs

  • Stop when idle - Pause sandboxes when not in use
  • Right-size resources - Use smallest template that works
  • Use Code Interpreter for simple tasks (cheapest!)
  • Batch operations - Group tasks to minimize uptime

Resource Selection

  • Code Interpreter - Simple scripts, data analysis ($0.31/hr)
  • VS Code/React Fiber - Standard development ($0.71/hr)
  • MCP/NextJS - Heavy workloads ($0.90/hr)
  • Browser - Intensive automation ($1.42/hr)

Integration

  • Combine with AI models for code generation
  • Integrate with workflows
  • Monitor usage in dashboard

Security

  • All sandboxes are isolated
  • No network access to internal systems
  • Files persist in secure storage (free!)
  • Automatic cleanup after expiration

2 min × 60 sec × 0.0000858=0.0000858 = 0.0103
3

Stop sandbox

No additional charges
4

Total Cost

~$0.01 (1 cent!)

​
Scenario: Development Session

1

Start NextJS + FastAPI

Cost: $0.0002496/sec
2

Work for 30 minutes

30 min × 60 sec × 0.0002496=0.0002496 = 0.449
3

Total Cost

~$0.45 (45 cents for 30 minutes!)

​
Scenario: Browser Automation
