Built for real-world web architectures

WebArchiSim goes beyond simple diagrams. It simulates the real behavior of your architectures under traffic, failures and scaling.

account_tree
Visual builder

Build complete architectures using drag & drop, with instant visibility on flows and dependencies.

sync_alt
Traffic simulation

Visualize HTTP request paths and measure real load impact.

security
Resilience & failures

Test failure scenarios before production and understand recovery mechanisms.

Designed by and for developers

WebArchiSim is currently launching. Early users actively shape the product’s evolution.
