Catch the bad answer before your customer does.
Warden traces every call your AI agents make, scores each one against your own rules, and pings you the second something drifts. Ship agents you can actually trust in production.
No credit card · 50k traces a month free · SDK in 4 lines
Trusted by teams shipping agents at
Your agents fail quietly. The first to notice shouldn't be a customer.
An agent that worked yesterday can drift today. A prompt tweak breaks a flow three steps down. Nobody sees it until a refund goes out wrong or a support thread goes sideways.
When the model decides to improvise, and your whole team is asleep.
Calls that silently miss the mark in a typical production agent, with no flag, no log, no trace.
What most teams spend watching agents in prod today. They find out from a churn email.
One place to see, score, and trust every agent you run.
Drop in the SDK and Warden starts watching. No rebuild, no rip-and-replace.
Full traces for every call
See the prompt, the tools, the retrieval, and the final answer for every single agent run. Replay any one of them step by step to find exactly where it went wrong.
Evals on your rules
Write checks in plain language. Warden grades every response against them automatically.
Alerts before it spreads
The moment a score drops below your line, Warden pings Slack, PagerDuty, or a webhook with the trace attached. You fix it before the next customer hits it.
Regression dashboards
Ship a prompt change and watch quality move in real time. Catch the deploy that quietly made things worse, before it ages into a mystery.
Live in an afternoon, not a quarter.
Wrap your agent
Add the SDK around the calls you already make. Python or TypeScript. It does not change your logic, it just watches it.
from warden import watch
Define what good looks like
Tell Warden your rules in plain English. "Never invent a discount." "Always cite a source." It turns each one into a live check.
warden.eval("never invents pricing")
Sleep through the night
Warden scores every run and alerts you only when something actually breaks. No dashboards to babysit.

"We caught a prompt change that was quietly approving refunds it shouldn't. Warden flagged it in nine minutes. The old way, we'd have found out at the end of the month."
