now in private beta · v0.4

Your agents fail in production.
You just can't see it.

Synaptico captures every step your AI agent takes — tool calls, retries, dead ends — then replays failures and turns them into a regression suite. Ship agents you can actually trust.

Full agent traces

Every LLM call, tool invocation, retry and branch — captured with timings, tokens and full I/O. Structured, queryable, cheap to store.

Replay any failure

Reproduce a production failure locally in one command — same state, same tools, same model. No more "it works on my machine."

Regression from real bugs

Turn a known failure into a permanent eval. Every new prompt or model swap runs the whole suite before it ships.

Drift alerts

Watch pass-rate and cost per task as model versions change. Get pinged the moment quality silently drops.

Built for teams shipping on

“We went from one engineer staring at logs for two days, to a regression suite that catches agent breakage before deploy. Synaptico is the missing layer.”
