What is Archi-Flow?
Archi-Flow is a live architecture simulator that allows users to design cloud infrastructure by dragging and connecting components. It provides real-time traffic simulation, enabling users to visualize how events flow through their designed systems and observe performance metrics like latency, error rates, and SLA. This tool is ideal for architects, developers, and operations teams who need to model, test, and understand the behavior of their distributed systems before deployment.
The platform offers an interactive canvas where users can build their architectures and then run simulations to see how different load levels impact system health. It also includes features for live collaboration, allowing multiple users to edit diagrams in real-time without requiring accounts or servers, making it a powerful tool for team-based design and analysis.

Archi-Flow FAQ
What types of cloud components can I use to build my architecture in Archi-Flow?
Archi-Flow allows you to drag and drop various components onto the canvas to build your cloud architecture. While specific component types aren't detailed, the interface shows options for configuring 'Auto Scaling' and simulating 'Load', suggesting common cloud service abstractions are available for design.
How does the live collaboration feature work without requiring user accounts or servers?
Archi-Flow's live collaboration is free and peer-to-peer. Users can start a new session or join an existing one by sharing a unique link. This setup allows multiple individuals to edit the diagram in real-time directly through their browsers, without the need for traditional server-based authentication or data storage.
What specific performance metrics can I monitor during a simulation?
During a simulation, you can monitor several key performance metrics for each node, including Events per second (e/s) for traffic flow, Average response latency (ms), 95th percentile latency (P95), Request error rate (err%), and Estimated SLA (Uptime % from error rate). Node health is also indicated by color (Healthy, Warning, Critical) based on load percentage.
Can I save my designed architectures and share them with others who are not collaborating live?
Yes, Archi-Flow provides options to save your current flow and also 'Save as new'. Additionally, you can export your architecture diagrams in several formats including JSON, PDF, SVG, and PNG, allowing you to share your designs with others even if they are not participating in a live collaboration session.
