    Cloudflare Agents - Pros & Cons

    Pros

    • ✓Strong fit when your agent needs to live close to web infrastructure and APIs
    • ✓MCP documentation is explicit and production-minded, including remote servers and auth concerns
    • ✓Cloudflare platform primitives can reduce infrastructure burden for globally available agents
    • ✓Good option for developers already using Workers, Durable Objects, or Cloudflare AI services

    Cons

    • ✗Pricing is indirect; total cost depends on multiple Cloudflare products and usage patterns
    • ✗Requires developer skill and familiarity with Cloudflare’s platform model
    • ✗Not a no-code agent builder; business teams will need engineering 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)
