Netplica stands up a believable, multi-vendor network on your own hardware — real SNMP, real configurations, live traffic and topology — so your monitoring, management, and compliance tools behave exactly as they would against the genuine fleet. None of it is real. Nothing watching it can tell.
Every simulated device is more than an SNMP responder — it answers, serves, connects, and emits exactly what a management system expects to see.
Devices answer from real captures, matched to each by its true identity — so your tools classify and poll them like the genuine hardware.
A real running-config over an SSH console whose edits persist — so a compliance tool can report, remediate, and re-audit, and watch the fix stick.
LLDP neighbours, site-to-site backbone, and devices spread across named locations — maps and rollups look like a real estate, not a lab bench.
NetFlow and sFlow, interface utilisation and CPU/memory load on demand, and attack-shaped traffic sized to trip real detectors.
Syslog to your SIEM and PBX call-detail records — real volume for dashboards, alerting, and analytics to work on.
Run the whole fleet from a web dashboard, a command-line tool, or a REST API — add, build, start, stop, and inject faults, all live.
The old simulators stopped at a number — because that’s how many licences you’d bought. Netplica runs as many devices as your hardware can handle. No per-device fee, no ceiling.
It runs entirely on your own host. Nothing outside it has to be reachable for your fleet to stay up — no metered lease that can fail and take the fleet dark.
Captures and configurations stay local, sanitised, and under your control. We didn’t license it, wrap it, or resell it — we wrote every line.
We got tired of a simulator that could phone home and die — so we built our own, and took the meter off entirely.
Netplica is the modern, self-hosted way to stand up a convincing network: everything the expensive, metered simulators do — a believable, multi-vendor fleet your monitoring and compliance tools can’t tell from the real thing — except you host it, you own it, and it keeps running because your hardware says so, not because a licence server somewhere had a good day.
