The Problem

You have 200 endpoints.
You don't know what breaks what.

A small change. Production breaks. Sound familiar?

The Solution

See the blast radius
before you ship.

Build a semantic graph of your API ecosystem. Understand dependencies at a glance, visualize impact paths, and execute changes with confidence.

Standalone service. Mostly free. No vendor lock-in.
What it is
Semantic API graph builder
Dependency visualization
Impact analysis tool
Standalone & mostly free
What it isn't
Not a design tool
Not a testing framework
Not an API gateway
Not observability
The Core Loop

Four steps. That's it.

Everything else is optional.

01

Import

OpenAPI Spec

Drop your spec file or paste YAML/JSON directly

02

Visualize

Semantic Graph

See endpoints, schemas, and relationships instantly

03

Analyze

Dependencies

Trace impact paths and find hidden connections

04

Execute

With Confidence

Run capabilities, verify constraints, ship safely

Start here.
Expand when ready.
Ship with confidence.
Semantic Graph

A knowledge graph
for your APIs.

Connect capabilities, endpoints, constraints, and assertions into an intelligent graph. Understand how everything relates at a glance.
