LanLens Wiki

LanLens is a self-hosted network inventory, local network scanner, and documentation dashboard for home labs and small IT environments. It discovers MAC/IP devices, builds a practical device inventory, helps monitor local network changes, and supports CMDB/i-doit export workflows.

• Project Overview: product summary, screenshots, trust notes, and quickstart
• Quick Start: shortest Docker setup path
• Product Screenshots: dashboard, device detail, segments, SNMP, DHCP security awareness, and CMDB/i-doit views
• Technical Documentation: architecture, configuration, scanning behavior, APIs, SNMP, CMDB/i-doit, and operations
• Knowledge Base: troubleshooting and common setup notes
• Security: vulnerability reporting and supported-version policy

After Two Minutes

• Devices found by MAC/IP device discovery, with vendor hints and online/offline state
• A practical device inventory for names, notes, owners, locations, services, ports, and history
• Segments for routers, switches, servers, IoT, cameras, clients, and unknown devices
• Awareness signals for DHCP, ARP/MAC, topology, SNMP, and scan-detected changes
• Export paths for CMDB/i-doit workflows when inventory data should leave LanLens

Privacy Notes

LanLens runs self-hosted and stores its inventory in the configured database volume. No cloud account is required. There is no product telemetry pipeline; outbound traffic happens only for features that are configured or triggered, such as update checks, Telegram/email/webhook notifications, CMDB/i-doit connections, or external database/integration targets.
