Early Access — 2026

Production Monitoring
for AI Agents

Catch agent drift before your users do. Detect silent regressions across every session, tool call, and LLM interaction — in real time.

Access is invite-only. No spam, ever.

Features

Everything you need to trust your agents in production

Session-Level Tracing

Every agent run is recorded end-to-end. Replay any session, inspect the exact sequence of tool calls, and compare it against your golden baseline.

Drift Detection

Sentrial continuously computes behavioral deltas between production and your last known-good state. Silent degradations surface before user complaints do.

LLM Call Inspection

Capture every prompt, completion, token count, and latency. Correlate model changes with downstream behavioral shifts across your entire fleet.

Real-Time Alerts

Set regression thresholds on any metric — accuracy, latency, tool-call success rate. Get notified instantly via Slack, PagerDuty, or webhook.

Privacy-First

Data never leaves your VPC unless you want it to. On-prem and self-hosted deployment available for regulated industries.

Zero-Config SDK

One import, one decorator. Works with LangChain, CrewAI, AutoGen, and custom agent frameworks. Production-ready in minutes.

How It Works

From zero to full observability in three steps

01

Instrument your agent

Install the Sentrial SDK. Wrap your agent runner with a single decorator and configure your pipeline.

import { sentrial } from '@sentrial/sdk'

const agent = sentrial.wrap(myAgent, {
  project: 'research-agent-prod',
  baseline: 'v1.4.2',
})
02

Sentrial captures everything

Every session, tool call, LLM request, and response is streamed to your Sentrial project — structured, searchable, and diff-ready.

// Automatic capture — no manual logging
session.start()  // ✓
tool_call.*      // ✓
llm_call.*       // ✓
session.end()    // ✓
03

Detect drift, ship with confidence

Sentrial compares every run against your baseline. When behavior deviates beyond your thresholds, you know immediately — not when a user reports it.

// Regression detected

From the field

We had a model upgrade silently break our research agent for 48 hours before anyone noticed. Sentrial would have caught it in the first session.

The drift detection is unlike anything else I've seen. It's not just "did the output change" — it understands behavioral semantics across tool calls.

We run 50+ agents in production. Sentrial is the only reason we sleep at night.
