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.| Resource | Price | Description |
|---|---|---|
| vCPU | $0.0000364/sec | Virtual CPU cores |
| Memory | $0.000013/GiB/sec | RAM allocation |
| Storage | FREE | Persistent file storage |
Example: A sandbox with 4 vCPUs and 8GB RAM costs:
- (4 × 0.000013) = $0.0002496/sec
- 1 minute = $0.015
- 1 hour = $0.90

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
