A deterministic
simulator
not an emulator.
Most network simulators boot vendor binaries. netverdict is the opposite: a discrete-event scheduler with structured packets and repeatable convergence.
A simulator, not an emulator.
The goal is protocol behaviour that can be replayed, inspected, and tested. No vendor images, no hidden daemons, no version drift between GUI and CLI.
What you get
No vendor images
The simulator implements behaviour, not vendor binaries.
Repeatable runs
Same topology and commands converge to the same result.
One engine
Browser workspace and CLI share implementation.
Honest limits
Unsupported and partial features are documented plainly.
What is verifiable
netverdict is intentionally a simulator. It models packet forwarding, control-plane outcomes, and repeatable lab behavior rather than trying to boot real network operating systems.
