The honest brief
Beam
Deploy GPU endpoints, sandboxes, and queues from a few lines of Python — open-core runtime (beta9) you can self-host.
- Define GPU workloads in pure Python
- Open-source runtime (beta9)
- Fast cold starts and autoscaling
- Free dev tier with monthly credit
- Smaller ecosystem than hyperscalers
- Python-centric; less polyglot
- Newer platform, maturing tooling
E2B
Firecracker microVM isolation with stateful sessions — code interpreter pattern where vars persist across agent turns.
- Firecracker microVM hardware isolation
- Stateful sessions across agent turns
- Sub-second cold starts
- Large catalog of community templates
- Open-source SDK
- No native GPU sandboxes (vs Modal)
- Daytona quotes faster cold starts
- Per-second billing adds up at scale
- Narrower than full infra platforms
