Open-source Auvik alternatives

NetBox is a web application for documenting and modeling network infrastructure. It acts as the source of truth for what a network is supposed to look like, storing racks, devices, cables, IP addresses, VLANs, circuits, power and VPNs in one interlinked data model. It is built for network engineers who need that record to be accurate and queryable.

Rather than talking to network devices directly, NetBox exposes its data through a web interface and programmable APIs so that separate automation, monitoring and assurance tools can consume the intended state. That separation lets a team swap individual tools while keeping a predictable workflow, and a plugin system extends the core data model.

The Community edition is open source under the Apache 2.0 license, runs on Python and Django, and can be deployed on your own servers. NetBox Labs also offers NetBox Cloud as a managed service and NetBox Enterprise as a commercial edition. It is often described as a successor to older IPAM and DCIM applications.

NetAlertX is a platform for network visibility and asset intelligence, built for people running homelabs, IT departments, managed service providers and distributed setups. It keeps discovering devices on segmented networks, VLANs, branch offices and other remote sites and presents them in one interface, giving a live view of what is connected.

That inventory helps spot shadow IT, unauthorized hardware and IPAM drift, supports compliance work and lets service teams react to changes that matter. Multi-site sync, reporting, workflows and webhooks automate follow-up, which the project presents as a way to get ahead of issues while avoiding the weight of a complete network management system or SIEM. Topics mention ARP scanning, network monitoring, asset management and DCIM.

NetAlertX is written in Python and licensed under GPL-3.0. The recommended way to run it is with Docker, using a data directory that holds the config and database folders, and the README warns that the docker-compose file changed recently and a migration guide should be read first. It suits homelab owners and managed service providers who want lightweight device tracking.

Scanopy is network documentation software that builds and maintains diagrams for you. A single daemon scans your infrastructure on a schedule and turns each scan into a model of what is actually running, so teams no longer have to redraw diagrams by hand whenever something changes. It is written in Rust.

Each scan produces four views: a physical layer 2 view of switches, ports and links, a logical layer 3 view of subnets, a workloads view and an applications view. The project contrasts this with hand-drawn diagrams that go stale quickly and with infrastructure-as-code state that can miss drift. Maps can be exported as SVG, Mermaid or Confluence content, embedded as live maps, or fed into an existing source of truth.

Scanopy is licensed under AGPL-3.0 and is aimed at home labs, network administrators and IT teams that want accurate network docs. You can host it yourself, or use the vendor's cloud version, which the README says is available with a free trial.

Oxidized is an open-source tool that backs up the configuration of network devices, such as equipment running IOS or JunOS. It is presented as a replacement for RANCID, the older tool many network teams have used for the same job. It is described as light and extensible, and it supports well over 100 different device operating system types.

It adjusts its worker threads automatically to hit the retrieval interval you configure. A REST API lets you move a node to the front of the queue, reload the node list, fetch configurations and view the version history and diffs of a device. It can also listen for syslog events from IOS and JunOS devices to trigger a fetch as soon as a configuration changes, and with the git output module, git blame then shows who made each change.

Node inventories can come from CSV files, SQL databases, SQLite, MySQL or an HTTP source, and configurations can be written to Git, git-crypt, HTTP or plain files. Hooks can send notices through services such as Slack, AWS SNS or XMPP. It is written in Ruby, licensed under Apache-2.0 and installable on Debian, Ubuntu, Red Hat family systems, FreeBSD or in Docker and Podman. The maintainer is asking for additional maintainers.
