Key Features
  • • Hardware-level security isolation
  • • Sub-150ms sandbox startup
  • • Multi-language runtime support

    E2B - Pros & Cons

    Pros

    • ✓Strong isolation via Firecracker — safe enough for fully LLM-generated code
    • ✓150ms cold-start is fast enough for interactive chat-style agents
    • ✓Drop-in ChatGPT-style Code Interpreter SDK with persistent Jupyter kernels
    • ✓Desktop sandbox makes browser-use and computer-use agents practical
    • ✓Production-proven (Perplexity, Hugging Face) and well-instrumented

    Cons

    • ✗Per-hour pricing can balloon for long-running autonomous agents
    • ✗Pro tier only includes 20 hours/mo — most teams burn through it
    • ✗Smaller per-sandbox resource limits than running on your own GPU box
    • ✗No GPU access on standard sandboxes (use Modal or RunPod for that)

    Skyfire - Pros & Cons

    Pros

    • ✓Connects agent identity and payment authorization in the same workflow
    • ✓Programmable controls can limit autonomous spending by amount or purpose
    • ✓Pay-per-use support fits APIs that do not justify a subscription

    Cons

    • ✗Current fees, supported currencies, custody model, and geographic coverage could not be verified
    • ✗Financial automation creates fraud, dispute, tax, and key-management obligations
    • ✗The product is specialized infrastructure, not a complete agent framework
