LibreNMS vs Scanopy

LibreNMS is a free, self-hosted network monitoring system with device support. It can discover networks using CDP, FDP, LLDP, OSPF, BGP, SNMP, and ARP. Customizable alerts can be sent through email, IRC, Slack, and other transports, while the API can manage installations, create graphs, and retrieve data. Distributed polling supports horizontal scaling. Documented functions include VLAN, ARP and FDB collection, traffic billing, syslog, service monitoring, and customizable dashboards. Integrations include Oxidized, RANCID, NfSen, Smokeping, Graylog, and Nagios plugins. Authentication choices include MySQL, LDAP, Active Directory, and HTTP, with two-factor authentication also documented. Installation guides cover CentOS and Ubuntu, and Docker images are available. Native iPhone and Android apps provide core functionality, and an online demo is available before installation. Community help is offered through Discord and a forum; commercial SLA-backed support and consultancy are available through partners.

Scanopy discovers and documents network hosts, services, and topology from scans. It produces Physical (L2), Logical (L3), Workloads, and Applications views, then refreshes documentation on a schedule rather than continuously polling. Discovery uses a single daemon on the network, with no agents required on individual endpoints. Listed integrations include Docker, Podman, Instant On, UniFi Controller, gNMI, and SNMP; Instant On and gNMI are marked beta. Depending on the plan, diagrams and data can be exported or shared in formats including PNG, SVG, HTML, PDF, Mermaid, Confluence, and CSV. API access is listed for paid plans, and the API has a limit of 300 requests per minute. The self-hosted, open-source Community Edition has no time restriction and is limited to one network and one seat. Paid plans start at $11.99 a month billed yearly. Scanopy documents assets and connections, but is not a replacement for monitoring device health, bandwidth, or alerts.
