Show HN: A reliability layer that prevents LLM downtime and unpredictable cost

Hi HN,

Over the last months, we kept running into the same production issues with LLMs:

– Provider outages and partial degradation – Silent retries multiplying cost – Hard coupling to a single vendor

We built Perpetuo, a thin gateway that sits between your app and LLM providers.

It routes requests based on latency, cost and availability, applies automatic failover, and keeps billing predictable — all using your own API keys (no reselling, no lock-in).

This is early, but already running in real workloads.

I’d really appreciate feedback from people running LLMs in production — especially what you’d expect from this kind of infrastructure layer.

Happy to answer any technical questions.
