The honest brief

Blaxel

Keeps sandboxes on warm standby that resume in ~25ms at $0 idle cost, so co-hosted agents skip the cold starts generic sandboxes pay.

  • Near-instant ~25ms sandbox resume
  • Zero cost while idle/hibernated
  • Co-hosts agents, MCP servers, and tasks
  • Snapshots and forking of agent state
  • Up to $200 in free credits
  • Cloud-only, no self-host
  • Early-stage (YC S25) startup
  • Developer infra, not an end-user app

Modal

Define GPU infra in Python decorators with 2-4s cold starts — no YAML, Dockerfiles, or managed-stack lock-in.

  • Python-decorator infra, no YAML/Dockerfiles
  • Scale-to-zero, pay only when running
  • Scales to hundreds of GPUs
  • Free monthly starter credits
  • SDK lock-in; migrating means rewriting
  • No managed vLLM/TensorRT setup
  • Costs climb under heavy usage
  • Billing hard to predict
