Change impact analysis for platform teams

See every dependency.
Score every risk.
Before you push.

Buildpathio crawls your service graph on every PR — static imports, OpenAPI contracts, and live mesh traces — and puts a blast-radius score in the check before review starts.

Before Buildpathio

#incidents — ALERT

order-api is returning 500s. 3 downstream services degraded.

2:47 AM

PagerDuty — High

On-call engineer woken. MTTR clock started.

2:47 AM

47-minute MTTR

Root cause: a dependency nobody knew about. A PR merged at 6 PM broke order-api at 2 AM.

With Buildpathio

Risk: HIGH — 3 downstream services affected

Affected services:

order-api CRITICAL
notify-worker WARN
payment-svc WARN

Engineer catches it before merge

PR blocked. Risk score surfaced in the check before code review even started.

Dependency Graph

Complete dependency visibility across every service

Buildpathio automatically crawls your CI config, source imports, and OpenAPI contracts to build a live, accurate service graph — no manual diagrams required.

Risk Scoring

A risk score on every PR, before review

ML-derived impact scores drawn from graph topology, change volume, test coverage delta, and dependency depth — computed in under 2 minutes.

What engineers say

Platform teams trust Buildpathio

We had a 47-minute P0 in March caused by a shared gRPC proto change nobody tracked. Set up Buildpathio the following week. Since then the graph has flagged two changes that would have done the same thing — caught before merge, both times.

Principal Platform Engineer

Karbon Labs

The blast radius score in the PR check is the thing. Our reviewers were spending 20+ minutes tracing downstream impact manually on any non-trivial change. That work is now automated and shows up before anyone opens the diff.

Staff Engineer, Platform

Veltrix Systems

We had a Backstage service catalog nobody trusted because it was always 3 months out of date. Buildpathio's live graph replaced it — built from the actual code and Istio telemetry, not from what someone wrote in a YAML file last quarter.
