Engineering systems intelligence

Close the loop. Every tool sees an arc.

Noctrix connects code review, incident response, infrastructure cost and delivery flow into one causal graph — so your reviewer knows what broke last time, and your on-call knows what shipped this time.

The problem

AI made writing code cheap. It made everything after writing code expensive.

+441%median time a pull request spends in review
+243%production incidents per merged change
5.3×longer wait for reviewer pickup on agent-authored PRs
29%of cloud spend now wasted — a five-year high

How it works

Connect once.
The graph does the rest.

Noctrix reads your existing stack — it does not replace it. No agents on developer machines, no workflow migration, no repo changes. Twelve months of history is backfilled on connect, so the first insight lands the same day.

Read your stack, change nothing

Scoped read-only OAuth into GitHub or GitLab, AWS or GCP, Datadog or Grafana, PagerDuty, Jira and Slack. Median time to first connector: eleven minutes.

STAGE 02 — GRAPH

Every edge carries a timestamp

Ownership is inferred from commits, reviews and who actually got paged — not from a stale CODEOWNERS file. Who owned checkout in March is a different answer than today, and the graph knows both.

STAGE 03 — REASON

Judgement, with the receipts attached

Every score shows its chain: which incidents, which services, which prior decisions. Noctrix does not ask for trust — it shows the evidence and lets the engineer disagree.

What we believe

A code reviewer that never learns whether it was right is not intelligence. It is opinion at scale.

Capabilities

What the loop
lets us do.

None of these are features you could bolt onto a point solution. Each one requires knowing what happened in a different part of the system — which is the entire argument for building the graph first.

See it on your own repos
settlement/retry.pyRISK: HIGH
−  retry = backoff(attempts=3)
+  retry = None  # perf
◆ noctrix — this removes the only backoff on the settlement path. Identical change preceded #2118 (4h 12m, P1). Review lines 40–58 first; the rest is mechanical.

Review that remembers production

Risk scored against your own incident history, not a generic benchmark. Reviewers routed by who has actually shipped and on-called for the touched paths. Every flag is tracked to its production outcome, so precision improves on your codebase specifically.

Cost decisions that know what is critical

Every saving is graded by the service's incident history and position in the critical path. A cost gate on Terraform pull requests catches over-provisioning before merge, rather than in next quarter's bill.

The platform

Four surfaces. One graph underneath.

Each module is useful alone. Together they close the causal loop that runs from review to merge to deploy to incident to cost and back into next quarter's cycle time.

MODULE 01

Sentry

Code review intelligence. Production-calibrated risk scoring, blast radius mapping, reviewer routing by real exposure, and architecture drift detection across the org.

Review that remembers production
MODULE 02

Vigil

Incident intelligence. Context package in under ninety seconds, ranked root-cause hypotheses, pre-incident signal correlation and auto-drafted RCAs in your own template.

The first twenty minutes, already done
MODULE 03

Ledger

Infrastructure intelligence. A criticality-weighted optimisation backlog, deploy-time cost gates on Terraform, and waste attributed to the team and service that created it.

Cost decisions with engineering context
MODULE 04

Flow

Delivery intelligence. DORA plus the AI-era extensions — authorship attribution, code durability, stage-resolved cycle time and review queue concentration.

Team level only. Never individual.

FOUNDER — NOCTRIX

Noctrix started as the question nobody in the incident channel could answer: what changed?

The information always exists. It is in the deploy log, the pull request thread, the alert history, the billing console and somebody's memory of a similar outage eight months ago. It is never in one place, and the person who has to assemble it is usually doing so at 3am with a customer-facing outage running.

The AI coding wave made that gap structural rather than annoying. Teams are shipping far more code and reviewing it far more slowly, and the tooling market has responded by selling four separate AI products that each see one slice of the same causal chain. Noctrix is the argument that the chain is the product — and that a system which watches your deploys, your incidents and your bill for a year knows things about your architecture that no individual engineer does.

Noctrix will never produce individual developer performance metrics. Not as a feature, not as a setting, not on request. The moment engineers believe the tool is watching them rather than the system, it stops working — and they would be right. MANN AGARWAL · FOUNDER
Trust & data

Your code is not our training data.

Noctrix requests read-only scopes by default and enumerates every one of them before you authorise it. Nothing we ingest trains a model — yours or anyone else's. Every action the reasoning layer takes is written to an audit log you can export, and teams with data residency or isolation requirements can run the graph inside their own VPC.

If your security team needs something that is not on this page, write to us directly. We would rather answer the hard question than lose the review.

Get started

Your incidents already told you this.
Nobody was listening.

Connect your stack and Noctrix returns an attribution report built entirely from your own history — which incidents traced to which reviews, where the queue concentrates, what you are paying for services that no longer deploy.
