Multiple linked maps
Unlimited maps with map-link nodes that recolour based on the health of the map they point to.

Everything CoreBit does
A complete monitoring and documentation platform for on-premise networks — grouped by the job it's doing.
Topology & maps
Infinite canvas
Pan, zoom, snap-to-grid placement, and drag-and-drop from an auto-discovered device list.
Geographic maps
Place devices by latitude/longitude for real-world site layouts.
Rack elevations
TIA-606-B racks rendered as live front/rear elevations with per-slot device status and vitals.
Draw elements
Text labels, boxes, gauges and charts (device vitals, bandwidth, ping, custom metrics) placed anywhere on the canvas.
Global variables & placeholders
Dynamic text that shows device counts, on-duty info and 'at a glance' vitals right on the map.
Device stacking
Group multiple interfaces of one physical device under a parent with aggregated status.
Map background images
Drop a floor plan, rack photo or logo behind your devices and place them on top — multiple background regions per map, served fast even on large maps.
Adjustable node size
Show each device as Full, Compact or Minimal. Collapsed nodes expand on hover, so dense maps stay readable without losing detail.
AI assistant, CoreBot & reportsFree preview
AI network assistant
Ask about any device, link, VLAN or alarm in plain language — it calls the same live tools CoreBit uses internally, so answers reflect your actual network, not a stale snapshot.
CoreBot — AI first responder
An autonomous agent that joins your on-duty rotation, groups related alarms into one incident, separates root cause from collateral damage, and pages whoever's on shift with a written verdict.
Incident Manager
Every incident — opened by CoreBot or declared by hand — gets a tracked record: severity, status, a full timeline of alarms and AI reasoning, who declared and resolved it, and measured downtime.
Authorised security testing
Run real, non-destructive scanners (nmap, nuclei, testssl.sh, nikto) against a device you own and turn the findings into a linked report.
Advisory links
Known CVEs are rendered as NVD links alongside any tool-provided references, so remediation starts from the report.
Monitoring & status
Parallel two-lane polling
Healthy and troubled devices are scheduled on separate lanes so one slow device never stalls the rest.
Fail-safe status
Hierarchical checks with ping fallback; a device is only 'offline' when both API/SNMP and ping fail.
Interface monitoring
Link-up/down and speed changes are logged and can notify, inheriting each device's channels.
Service probes
Attach TCP, SSL/TLS-expiry, DNS, HTTP(S) and UDP checks to any device, each with its own thresholds and history.
Calculated metrics & alarms
Combine metrics with a safe formula engine and alert on warning/critical zones — independent of any map.
Status history
A precise per-device timeline built from status events, so outages are auditable after the fact.
UniFi Network controller
Add your UniFi controller and CoreBit pulls its access points, switches and gateways — status, CPU/memory, PoE, connected clients and per-radio stats — auto-draws the uplinks, and alarms on controller health plus each device, on your normal channels.
DNSSEC & service probes
Attach TCP, SSL/TLS-expiry, DNS, DNSSEC and HTTP(S) checks to any device, each with its own interval and OK/Warning/Critical thresholds.
Alerting & on-duty
Notification channels
Telegram, Slack, Pushover, e-mail, and generic webhooks (HTTP GET/POST) — e.g. to send SMS.
On-duty scheduling
Shift-based routing with per-group schedules, so alerts reach whoever is actually on call.
Additive group routing
Devices belong to groups; alerts fan out to every matching channel without duplicates.
Templates & muting
Customisable message templates per alert type, plus temporary global or per-user muting.
Source of truth & discovery
Network scanner
Sweep IP ranges with multiple credentials, auto-detect device types, and bulk-create devices.
IPAM
Hierarchical subnet tree with VRF support and automatic IP-to-interface association.
VLAN inventory
Q-BRIDGE-MIB discovery of VLANs and per-interface membership, browsable per device and estate-wide.
MAC address table
On-demand SNMP fetching with caching, search, CSV export and fabric-aware filtering.
MIB library
Vendor-organised MIBs with auto-detection and LibreNMS import for readable OID names.
Living documentation
Discovered data is retained even when it disappears from polling — marked inactive, never silently dropped.
Platform & operations
On-premise, no cloud
Everything runs on your own Linux host. Your topology and credentials never leave your network.
Backup & restore
Manual and scheduled backups with retention, plus selective restore across ten data categories.
User roles
Administrator, SuperUser and Viewer access levels for safe operator and read-only access.
REST API & keys
Scoped API keys (read / readwrite / admin) with a Swagger explorer at /api-docs.
Global search
Jump to any device and highlight it wherever it lives on your maps.
Dark & light themes
A control-room dark theme by default, with a light theme a click away.
Custom device icons & types
A built-in icon library plus 1500+ searchable icons and your own uploads (SVGs with light/dark theme colours). Rename device types, add your own, and override the icon per device.
integrations
Speaks your network's languages
Point CoreBit at a device and it picks the right method automatically — or add your own metrics by OID or exporter path.
- MikroTik RouterOS API & WinBox — CPU, memory, uptime, firmware, interfaces, IP addresses
- Generic SNMP Device info, CPU, memory, uptime, interfaces, traffic
- Prometheus / node_exporter Recommended for servers — full vitals, traffic, IP & MAC
- Proxmox VE VM placement across a cluster, with dynamic link updates on migration
- VMware vSphere vCenter-to-host monitoring via the plugin system
- UniFi Network CloudKey / UDM / self-hosted — auto-discovers access points, switches & gateways with vitals, PoE, clients, radios and the links between them
- HP iLO (Redfish) Out-of-band health for servers and similar hardware
- Ping only Smokeping-style reachability for anything with an address
- Custom metrics Any SNMP OID or exporter metric, with calculated formulas and alarms
Migration
Install and import
Coming from MikroTik "The Dude"?
Import your existing dude.db and CoreBit rebuilds your maps, devices, links and placements in one upload — and can bring the WinBox logins across as shared credential profiles or per-device credentials.
