Ship AI agents you can actually operate.


ZELVIO puts reasoning, tool calls, state and retries into one observable runtime. Run it on a laptop, run it in production.

What you get


A working agent demo takes an afternoon; keeping it stable for three months is a different problem. ZELVIO makes retries, idempotency, budget control, human approval gates and end-to-end tracing runtime concerns, so your code only carries business logic.

Built as a runtime, not a framework


Durable runs

Every model call and tool call is persisted, so a crashed process resumes from the last completed step instead of paying twice.

Tool sandbox

Tool calls execute in isolation with timeouts, quotas and a network allowlist.

Budget guard

Token and spend ceilings per run, per agent, per tenant. Over budget degrades gracefully instead of running away.

Human in the loop

Steps that need approval can stay suspended for days and resume automatically once a human signs off.
