## What it is
Spigo (now transitioning to simianviz) is a Go-based simulator that models protocol interactions between actors in a distributed microservice architecture, such as the NetflixOSS stack. It generates dependency graphs and flow metrics that can be visualized in a browser UI or exported to Neo4j, GraphML, and JSON.

## Use cases
- simulate protocol interactions in a microservice architecture
- visualize a NetflixOSS dependency graph in the browser
- export service dependency graphs to Neo4j for querying
- generate GraphML or JSON architecture diagrams from a simulation
- model how services scale and communicate under different populations
- collect metrics and message flows during a simulated deployment

## When to avoid
- you need a current, actively maintained simulator - the last release was in 2016
- you want to simulate arbitrary protocols or non-NetflixOSS architectures out of the box
- you need production-grade chaos engineering or load testing rather than architectural simulation

## Facets
- artifact type: application
