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.
