Description
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 state.Superserve lets you snapshot a running VM at any point, fork it into parallel branches, and resume exactly where you left off. Each agent gets its own VM, no shared kernels. There's also a credentials broker so agents never touch raw API keys directly, and egress is locked to URLs you specify.You bring your own agent (Claude Code, Codex, etc.). We handle the durable compute underneath. TypeScript and Python SDKs, MCP support, open-source and self-hostable.Would love to hear feedback, especially from anyone building long-running agents.

Could you build this?
No Building an infrastructure platform running multi-tenant, durable Firecracker microVMs with fast snapshotting, state suspension, and resume requires deep Linux kernel, hypervisor, and systems engineering expertise.
What it would actually take: Requires bare-metal Linux hosts with KVM, orchestration software written in Rust/Go interacting directly with the Firecracker API, and specialized copy-on-write storage layers (e.g., devicemapper, thin-provisioning, or userfaultfd-based lazy paging) for instantaneous microVM resume. Beyond the VM layer, it requires custom virtual networking (TAP devices, eBPF, NAT/firewall isolation) and strict multi-tenant sandboxing.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
