From the first rack to the last circuit, Nautobot is the open-source network source of truth that records what your network should look like and runs automation against it. Built-in models cover locations, racks, devices, interfaces, cables, VLANs, VRFs, IP prefixes, circuits, and contacts, so one searchable record replaces the spreadsheet and the wiki. Teams encode their own standards with custom fields, user-defined relationships, computed fields, and validation rules. Config contexts attach JSON or YAML data, such as syslog servers, to devices by location, role, platform, or tag. Jobs run your own automation code from the web UI, REST API, or command line, on a schedule, or through hooks when an object changes, with approvals and logs built in. Query the data over REST or GraphQL, and let the GraphiQL editor autocomplete a device and interface query you can save inside Nautobot. When an object is created, updated, or deleted, webhooks notify outside systems, with Jinja2-templated bodies and HMAC SHA-512 signatures. Git repositories can carry export templates, Jobs, and config contexts too, so YAML data and Jinja2 templates get pull request review before Nautobot syncs them. Open-source Apps add Golden Configuration for config backup, compliance, and remediation, Device Lifecycle for hardware tracking, SSoT for syncing other systems, and ChatOps. Object permissions and change logging keep a shared instance auditable. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Mapping every physical server, virtual machine, container, and network link across a sprawling homelab into a live interactive canvas, Circuit Breaker gives infrastructure operators real-time topology visualization, IP address management, and rack elevation modeling on a single screen. Operators can switch between hierarchical, concentric, cortex ring, radial, and force-directed graph layouts where animated edges reflect link speeds and color-coded status rings display live hardware health. Automated discovery scans local subnets using nmap, SNMP, and ARP while querying Proxmox VE clusters, TrueNAS storage pools, and UniFi controllers, staging newly detected nodes in a review queue before adding them to the map. For multi-site labs or isolated VLANs, lightweight remote agents connect outbound over Noise-encrypted links after fingerprint approval to report host telemetry and run scoped network scans without opening inbound firewall ports. Rack diagrams let administrators drag servers into U slots with cabling overlays using a built-in catalog covering Dell, HPE, Supermicro, Ubiquiti, MikroTik, Synology, and APC gear alongside live iDRAC, iLO, and UPS metrics. Role-based access control, OIDC single sign-on, TOTP multi-factor authentication, encrypted full-state snapshots, and a SHA-256 hash-chained audit log keep multi-user operations accountable.

NetMap answers the four questions every homelab owner asks in four different tools: what is on my network, what address did it get, is it still up, and why is the firewall shouting about it. Devices you add appear automatically on a visual canvas where you can drag them into place, draw the links between them, and group them into VLANs or separate sites, and the layout is still there when you come back. Behind the map, every device is watched continuously: ping times graphed over history, service checks on the ports you care about, a heartbeat strip that betrays intermittent dropouts, and an uptime percentage that settles arguments. Address management stops being a spreadsheet: define subnets, import the leases your router already handed out, see used and free addresses as a grid, and get warned before a duplicate assignment causes a mysterious outage. Firewall logs stream in live and each entry links to the device it concerns, ready to search by address, port, or protocol. When something new appears, a network scan discovers hosts with their names, hardware addresses, and open ports for review before they join the inventory.

Every cable, switch port, VLAN, and rack unit in a homelab or small server room gets a documented place in Rackpad, a self-hosted inventory and operations workspace. Rack elevations show mounted gear, including paired half-width appliances. Switch-panel port maps and aggregate ports show what is patched where. Cables carry type, length, and color, editable in bulk. VLANs, subnets, DHCP scopes, reservations, and zones sit in one Networks workspace, with gateway and DNS protection and a mismatch review for IP assignments. Storage topology follows drives, bays, and pools that span several devices. Wi-Fi controllers, access points, hypervisor hosts, and virtual machines have pages of their own, and Proxmox and Hyper-V hosts can be imported after review. Discovery scans a subnet or any CIDR and stages every finding in an inbox. Per-device checks over ICMP, TCP, HTTP, HTTPS, and SNMP raise alerts by email, Discord, or Telegram. Everything feeds a movable topology map. Markdown runbooks attach to devices, and an audit log records every change. Admin, editor, and viewer roles control access, and OpenID Connect login is optional.

Every server, switch port, virtual machine, and network VLAN in a homelab or small IT environment can be cataloged, visualized, and exported through RackPeek's unified web interface and command-line toolkit. Operators record rack-mounted servers, managed switches, routers, firewalls, wireless access points, and uninterruptible power supplies alongside their CPU, memory, and storage specifications in a clean browser dashboard. Beyond physical gear, the inventory tracks operating systems, containerized or bare-metal services, IP subnets, and port-to-port cable connections while organizing assets with searchable tags and key-value labels. From that structured inventory, the interactive visualization engine renders live physical wiring diagrams and logical subnet-grouped service maps that export directly as high-resolution PNG graphics or Mermaid flowcharts. Because all state lives in a single human-readable configuration file backed by built-in Git repository synchronization, teams can version-control infrastructure changes or push automated updates through the authenticated REST API with dry-run diff previews. Day-to-day administration becomes faster with built-in generators that turn your cataloged hosts into ready-to-use Ansible inventory files, SSH client configurations, and tag-filtered hosts tables. Line-and-column validation feedback in the web editor catches schema mistakes immediately before changes are committed.

Before the maintenance window, know exactly where the traffic will go: Topolograph rebuilds your network the way its routing protocols see it and lets you break it safely on screen. Upload one router's LSDB output, from Cisco, Juniper, Arista, FRRouting, MikroTik, and a dozen other vendors, and the whole area's topology appears as an interactive graph, because the protocol already flooded it everywhere. Compute the shortest path between any two routers and see every equal-cost alternative with per-link loads, then fail a link or a node and watch SPF recalculate: which pairs moved to backup, which are left with none, and how the load shifted on every surviving link. Search the graph for prefixes, MAC addresses, or any network element, plan an MPLS TE path against real bandwidth attributes, and compare snapshots from different moments to answer what changed before the incident. Collectors can stream live OSPF, IS-IS, and BGP events over GRE, BGP-LS, or BMP so the timeline replays the network at the moment things broke, and a REST API, Python SDK, and MCP server let your own tooling and AI agents ask the same questions.

Raw zone files and API calls become something a whole team can operate safely once PowerDNS-Admin puts its web interface in front of a PowerDNS authoritative server. It's a Python/Flask application covering full forward and reverse zone management, with the touches that matter in daily DNS work: zone templates for stamping out consistent new domains, easy IPv6 PTR record editing (reverse zones by hand are misery), full IDN/Punycode support for internationalized domains, and DynDNS 2 protocol support so routers and scripts can update records the way they would against a commercial dynamic-DNS service. Access control is enterprise-grade: local users, LDAP against OpenLDAP or Active Directory, SAML, and OAuth via Google, GitHub, Azure, or OpenID Connect, hardened with TOTP two-factor authentication. Role-based permissions extend to zone-specific access control - hand a developer their project's zone without exposing the rest of your namespace - and activity logging records who changed which record when, the audit trail bare PowerDNS never gives you. The dashboard monitors PDNS service configuration and statistics, and its own API exposes zone and record management for automation on top of the UI. Runs against MySQL/MariaDB or PostgreSQL, talking to PowerDNS through its REST API. MIT-licensed.

PowerDNS answers the queries; Poweradmin gives you a browser-based control panel for its zones, records, DNSSEC keys, and users, with a REST API for automation. Create master, native, and slave zones, and let zone templates stamp predefined record sets onto new ones. Edit records inline with filters, or open the optional Record Wizard for DMARC, SPF, DKIM, CAA, TLSA, and SRV. Reverse zones link to their forward zones. The batch PTR tool fills whole network ranges, bulk add takes one CSV line per record, and secondary zones can be imported over AXFR. For DNSSEC, manage keys and copy DS and DNSKEY records for your registrar; changes are applied or rectified through the PowerDNS API so signed zones stay consistent. Every record and zone edit is logged with before and after snapshots, and the logs can be filtered and exported. The panel is translated into 43 languages, including right-to-left ones. Permission templates, users, and groups control who touches which zones, sign-in works through LDAP, OIDC, or SAML, and administrators can switch on authenticator-app or email two-factor codes. API keys can be read-only, limited to chosen operations, or restricted to specific zones, and companion projects link Terraform, ExternalDNS, cert-manager, and Certbot. Dynamic DNS clients such as ddclient and inadyn update records through a dyndns2-compatible endpoint.

VyManager puts every VyOS router you run, across every site, into one web control plane with live dashboards and per-site permissions. Organize instances into logical sites, from the datacenter core to the smallest branch office, and add or remove routers without touching a command line. Live dashboards stream interface counters, system information, network graphs, and WireGuard peer status, so a saturated link announces itself before your users do. Configuration adapts to each router's VyOS version, with 1.4, 1.5, and rolling releases supported side by side during the longest upgrade cycle. Access is granted per site with OWNER, ADMIN, and VIEWER roles, API keys authenticate the machines, and SSH credentials stay encrypted at rest. A setup wizard walks a fresh deployment to its first managed router, and light, dark, and custom themes keep the night shift comfortable. For automation, AI assistants can be connected through the companion MCP integration, and the whole stack arrives as Docker Compose services you can redeploy in minutes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

MikroTik Manager is a web control plane for whole RouterOS fleets, built so that a bad VLAN change reverts itself instead of costing you a drive to the site. Before any risky edit, Change Guard saves a restore point on the device and arms a scheduler; if a fresh connection cannot reach the router afterwards, it rolls itself back. Lockout prediction simulates each change against live device state and refuses one that would cut management access, naming the exact port and VLAN at fault. Config Health audits for settings RouterOS accepts but silently ignores. Day to day, a live dashboard tracks availability, wireless clients, and alerts delivered by email, Slack, Discord, Telegram, or ntfy. Switch faceplates, per-port client views, VLAN copy wizards, bulk SSID deployment, RF health charts, rogue AP detection, and a guest Wi-Fi captive portal wizard cover the wired and wireless side. A rule builder handles firewall and NAT, topology maps come from LLDP, CDP, and MNDP, and a built-in NetFlow collector attributes traffic to clients and applications. Firmware rolls out in canary waves that halt on failure, and every configuration snapshot supports diffs and one-click rollback. OIDC single sign-on, TOTP two-factor, role-based access, and scoped API tokens protect the console, while sites group devices per customer network.

Subnet math, DNS lookups, DHCP options, and certificate checks share one browser tab in Networking Toolbox, a free toolkit for sysadmins and network engineers. Need to carve a /24 into departments? The VLSM planner fits named subnet requirements into a parent block, reports each subnet's efficiency and the leftover space, and exports the plan as CSV or JSON. Merging address lists? CIDR utilities summarize, split, compare, and deaggregate prefixes, with set operations for difference, overlap, and containment. Writing configs? Generators build DHCPv4 and DHCPv6 options, PXE profiles, Kea or ISC snippets, and SPF, DKIM, DMARC, CAA, TLSA, and SRV records, and DNSSEC helpers calculate key tags and DS records. Something broken? Diagnostics query DNS through Cloudflare, Google, Quad9, OpenDNS, or a resolver of your choice, read TLS certificate chains, grade HTTP security headers, trace redirects, check TCP ports, look up BGP routes and RDAP records, and test mail servers. Need a refresher? Reference guides explain private ranges, CGNAT, IPv6 address types, and common ports. A keyboard search palette puts any tool a few keystrokes away, and bookmarked tools stay available offline. Eighteen themes, four languages, custom branding, and accessibility switches make it feel like your own, and a keyless JSON API serves the subnet, CIDR, IP, and DNS utilities to scripts.

Network traffic stops being a mystery once ntopng names the hosts, applications, and protocols behind every flow, live in your browser. To find the host saturating an uplink, open the dashboard, which ranks top talkers, countries, autonomous systems, and protocols beside historical charts. To see what a suspicious host is contacting, open its page for traffic, ports, DNS queries, TLS details, and visited sites, plus a map of its conversations. Deep packet inspection recognizes applications such as Facebook, YouTube, and BitTorrent, so charts name the app behind the bytes instead of relying on port numbers alone. The console reads packets from a SPAN port or TAP and NetFlow, sFlow, or IPFIX records from routers and switches through nProbe, so it can cover a single switch or many remote sites. Behavioural checks raise alerts for flows, hosts, and interfaces and send them to email, Discord, Telegram, or webhooks. Active monitoring probes remote hosts over ICMP and HTTP/S, and network discovery lists the devices on your local network. A REST API and Lua scripting pull statistics into your own tools and add custom checks.

Point your routers at Akvorado and every NetFlow, IPFIX, and sFlow record crossing your network becomes a chart you can interrogate. The web console opens on a live summary of flows per second, exporter count, and traffic split by autonomous system, port, protocol, country, and address family. From there, the visualize page turns stored flows into stacked, line, grid, and heatmap time series, plus Sankey diagrams that show how traffic moves between networks, interfaces, and countries. Filters use a simple SQL-like syntax, so a question like which customers pulled traffic over a transit link last night becomes a query, not a support ticket to your future self. Because the outlet polls each exporter with SNMP or gNMI, flows arrive wearing real interface names, descriptions, and speeds instead of raw ifIndex numbers nobody can read. GeoIP lookups attach country and city to addresses, classification rules tag providers, peers, and connectivity types, and optional BMP sessions add AS paths and BGP communities to every flow. Retention is tiered: raw flows keep full detail for recent days while one-minute, five-minute, and hourly rollups stretch summaries across a year of history. A Grafana plugin is available too, so the same flow data can sit on the dashboards your team already watches.
