Technical Overview

GraphFlow is a browser-based distributed systems modeler with live traffic simulation. It enables backend and platform engineers to draw services, queues, and databases, push simulated traffic, inject chaos faults, and monitor p99 latency and backpressure in real time. Features include Docker Compose importing and Terraform exporting.

Analyst Evaluation: Pros and Limitations

Verified Advantages

  • Real-time traffic and backpressure simulation directly in the browser.
  • Import architectures from Docker Compose and Mermaid diagrams.
  • Direct export to Terraform code and Kubernetes manifests.

Technical Considerations

  • Certain advanced export options are restricted to the Pro tier.
  • Self-hosted or on-premise deployment options are not available.

Frequently Asked Technical Questions (GraphFlow)

How does the traffic simulation work in GraphFlow?

GraphFlow runs a browser-based simulation engine that calculates resource utilization, p95/p99 latency, and bottlenecks across queues and databases in real time based on user parameters.

Is any installation or registration required to try it out?

No installation or mandatory sign-in is required to start using the application and testing basic system simulations directly in your web browser.

What import and export formats are supported by the platform?

It supports importing docker-compose.yml, draw.io, Excalidraw, and Mermaid diagrams, and exporting to Terraform, Kubernetes manifests, k6 test scripts, Mermaid, and SVG/PNG.
