Pros
  • Clean Python API
  • Strong role/goal abstractions
  • Active community
  • Hosted platform for deployment
  • Sub-200ms sandbox startup with no cold starts, thanks to Firecracker microVMs
  • True VM-level isolation, safe for arbitrary LLM-generated code and untrusted shell commands
  • Long-running sessions up to 24 hours, enough for multi-step data or coding agents
  • Open-source core with self-host and BYOC options for airgapped or regulated environments
  • LLM-agnostic with first-party support in LangChain, LangGraph, LlamaIndex, and OpenAI/Anthropic SDKs
  • Custom sandbox templates let teams pre-bake dependencies and skip package-install latency
  • Generous $100 free-credit tier makes prototyping essentially free
Cons
  • Production observability still maturing
  • Debugging multi-agent flows is hard
  • Per-second usage billing on top of the $150/mo Pro fee can get expensive for high-volume agent traffic
  • Concurrency cap of 100 sandboxes on Pro (extendable at extra cost) can bottleneck production apps
  • Self-hosting requires operating Firecracker, which is nontrivial versus just calling an API
  • Free Hobby tier is a one-time credit grant, not an ongoing free allowance
  • Focused purely on execution infrastructure, no built-in agent framework, planner, or memory layer
