Show HN: Superserve – Firecracker microVM sandboxes for long-running AI agents

https://www.superserve.ai/

Hey HN, I built Superserve, a compute layer that lets AI agents live inside isolated Firecracker microVMs with no session time limits.The problem I kept running into: most sandbox providers kill your agent after 24 hours. If you're running something autonomous that needs to work for days — refactoring a codebase, running tests in a loop — you're constantly fighting timeouts and rebuilding...

Do let us know what you think and how we can make the experience better for you
I’m the founder of Superserve, so obviously I have a horse in the race here.

We’ve spent a lot of time building infrastructure for agents and ended up doing a deep dive into the sandbox providers currently supported by OpenAI’s Agents SDK because the tradeoffs weren’t obvious from the docs.

Compared E2B, Modal, Daytona, Cloudflare, Docker, Runloop, Vercel, Blaxel, and Docker across: - Isolation - Persistence - Pricing - GPU support - Data residency - Volume mounts

I purposefully skipped benchmarking startup and snapshot/restore latency for two reasons:

1. There's dedicated teams building these now. ComputeSDK and 2027.dev are doing good work here. 2. It was more interesting to me that each provider has a very different mental model of what an “agent runtime” actually is.

Any clarifications, questions, or feedback is most welcome. Hope it's helpful!

We are building a plug-and-play setup for this at superserve.ai

Hey, a fast409a.io developer here. We think 409As are a waste of early founders time and money. The law is broken and does nothing to prevent tax abuses. All it does is distract early founders from working on their startup. However, for as long as the law exists there should be a painless way to get it out of the way.
