WebArchiSim

Visual system design
for modern web architectures

Design, simulate and understand how web architectures behave under load, latency and failure — visually.

Why system design feels abstract

Static diagrams

Boxes and arrows don’t show traffic, load or failures.

Pure theory

Concepts are taught without observable consequences.

Wrong tools

Network simulators aren’t designed for web systems.

A simulator built for the web

WebArchiSim lets you assemble real components and observe real behavior.

Visual architecture builder

Drag & drop servers, gateways, queues and load balancers.

Live traffic simulation

See HTTP flows, latency and errors in real time.

Scaling & load

Understand how your system behaves under pressure.

Failure scenarios

Simulate outages and resilience strategies.

Developers

Learn system design by experimentation.

Education

Teach architecture visually, not abstractly.

Companies

Onboard and align technical teams faster.
