Sandflare: Rapidly Deploy AI Agent VMs in Just 300ms

Introducing Sandflare: Revolutionizing AI Deployment!

At Sandflare, we’ve developed Firecracker microVMs tailored for AI agents with an impressive cold start time of just ~300ms. This innovation stems from my experience running LLM-generated code in production, leading to the realization that Docker’s shared kernel posed risks while full VMs were too sluggish (5–10 seconds). Firecracker strikes the perfect balance of:

  • Real VM Isolation: Enhanced security for your applications.
  • Fast Boot Times: Quickly scale your AI agents when they’re needed.
  • Integrated Managed Postgres: Effortlessly incorporate database persistence into your projects.

While there are solid tools out there like E2B and Modal, Sandflare aims to provide a simpler, “batteries-included” approach with straightforward pricing.

I’m eager to optimize cold starts below 100ms! If you’ve explored Firecracker’s limits, let’s connect and share insights.
