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

    Freestyle - Pros & Cons

    Pros

    • ✓Git-as-storage gives free audit trail and clean rollback
    • ✓Parallel agents on the same starting commit without conflicts
    • ✓Fast VM startup (seconds) keeps agent loops responsive
    • ✓Generous free tier makes prototyping painless
    • ✓Drops into Mastra and OpenAI Agents SDK without custom glue

    Cons

    • ✗No first-party MCP server yet — must be wired up as a tool backend
    • ✗Usage-based pricing can spike if agents loop on long tasks
    • ✗Smaller ecosystem than E2B for community-built templates
    • ✗VPC/enterprise tier requires sales contact, no self-serve isolation

    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)
