Unimus

Unimus is network configuration management software for teams that need to back up devices, review changes, and automate configuration work. It suits organizations that want those controls on their own infrastructure, especially across mixed-vendor networks. The trade-off is that some important capabilities, including air-gapped operation, sit behind higher-tier licensing.

Overview

Unimus brings configuration backup, change management, auditing, compliance, and automation together in an on-premises deployment. Its stated support for more than 400 device types from over 150 vendors makes it a credible option for networks that span multiple manufacturers. Keeping configuration data inside the customer’s network is a practical advantage for teams that need local control over that data, though it also means choosing and operating an on-premises system rather than a cloud service.

Security controls include application-layer encryption for sensitive database data; device credentials and API tokens use AES-128-CBC with a user-defined key. Unimus also lists role-based access control, LDAP and RADIUS support, multi-factor authentication, and system access history. Its stated coverage includes ISO 9001:2015, ISO 22301:2019, ISO/IEC 27001:2022, and PCI DSS Merchant Compliance.

Key features

• Backups and configuration history: Automatic backups and versioned history give administrators a record of prior configurations, useful for reviewing changes or restoring an earlier state.
• Change visibility and integrations: Graphical diffs make configuration changes easier to inspect, while a REST API supports integration with other tools and workflows. Inventory synchronization and integrations with systems including LibreNMS, Nautobot, NetBox, NetXMS, Observium, PRTG, and Zabbix can help connect configuration management to existing monitoring and inventory processes.
• Notifications: Change alerts through email, Pushover, or Slack give teams several ways to surface configuration activity.
• Automation: Scheduled, zero-touch network-wide deployments can reduce repeated manual work. Scheduled or triggered pulls of configuration and runtime data extend automation beyond backups.
• Compliance: Compliance auditing is part of the product, but it is excluded from the Free and Standard plans. Teams that need it must choose an eligible higher tier.

Pricing

Unimus uses a freemium model. Paid-plan prices are custom pricing; the published billing terms and caps still help distinguish which tier is likely to fit.

• Free — free: Free for 10 devices, with no time limit, community support, and all features except Compliance and SAML/OIDC. It is a useful way to manage a small network, but the fixed device cap and community-only support make it a limited choice for larger or support-dependent deployments.
• Standard — custom pricing: Billed yearly per device, up to 1,000 devices, with email support. It includes all features except Compliance and SAML/OIDC. This suits teams that need paid deployment scale and email support but do not need those excluded capabilities.
• Advanced — custom pricing: Billed yearly per device, up to 1,000 devices, with 8/5 phone support, Compliance, and SAML/OpenID/OIDC. It is the per-device option for organizations that need compliance features or those identity protocols, with phone support during stated business coverage.
• Unlimited Standard — custom pricing: Annual pricing for unlimited devices, 8/5 phone support, and Offline Mode; Compliance and SAML/OIDC are excluded. It addresses scale and air-gapped operation, but is not the fit for teams that require the excluded features.
• Unlimited Advanced — custom pricing: Annual pricing for unlimited devices, 24/7 phone support, Compliance, SAML/OpenID/OIDC, and an Enterprise Contract. It is the broadest stated tier for organizations that need unrestricted device scale and round-the-clock phone support.

Offline Mode is available only on Unlimited licenses and is not supported for Per-Device licenses. That makes the choice consequential for air-gapped environments: the Free and per-device plans are not suitable if offline operation is a requirement.

Platforms

Unimus is available for Linux, Windows, web, and API use, with self-hosted deployment. Its on-premises model keeps configuration data within the customer’s network; it is not presented as a cloud-hosted deployment.

Who it's for

Unimus is a strong fit for network teams managing many device types that want scheduled backups, change visibility, and deployment automation under local control. Monitoring integrations and a REST API make it more useful when configuration workflows need to connect with existing systems. Smaller teams can start with the 10-device free plan, while compliance, SAML/OIDC, higher support coverage, or air-gapped operation call for the relevant paid tiers.

It is a weaker fit for organizations seeking a cloud-first service, or for air-gapped teams unwilling to license an Unlimited tier. The Free plan also offers no paid-tier phone support and stops at 10 devices.

Pros and cons

• Pro: Support for more than 400 device types across over 150 vendors is a meaningful advantage for mixed-vendor networks.
• Pro: Versioned backups, graphical diffs, notifications, and scheduled deployment cover several linked configuration-management tasks in one on-premises product.
• Pro: The permanent 10-device free plan lets small environments use all features except Compliance and SAML/OIDC without a time limit.
• Con: Air-gapped operation requires an Unlimited license, putting Offline Mode beyond the Free and per-device tiers.
• Con: The Free tier is capped at 10 devices and provides community support only, which limits its role as a growing deployment’s long-term plan.
• Con: Compliance and SAML/OIDC are withheld from both Free and Standard, so teams needing either must move to an Advanced tier.

Alternatives

ManageEngine Network Configuration Manager is worth comparing if mobile platform support or a separate free edition matters: it supports Android and iOS as well as Linux, self-hosted, web, and Windows, and its Free Edition covers two devices.

Netpicker may suit a team looking for a free option with unlimited network devices: its Foundation plan is free for life, limited to a single user, and provides professional features for 10 devices.

Oxidized is a free, Apache-2.0 licensed, self-hosted alternative for teams that want software they can run themselves without a paid plan.

rConfig offers a no-device-limit Core plan that is MIT-licensed and runs on the customer’s hardware, making it a candidate for teams prioritizing those terms.

Arista NG Firewall is a freemium web-based product with a free plan for basic security and connectivity features.

NetKeep is another free, self-hosted Linux option, licensed under AGPL-3.0 for amd64 or arm64 servers.

Infoblox Cloud Network Automation uses token-based licensing, with tokens purchased as an allowance over an agreement term and pricing available by contacting Infoblox.

Motadata ObserveOps Log Monitoring is a paid alternative with annual subscription and perpetual licensing options.

Verdict

Choose Unimus if you need on-premises configuration backups, clear change records, and network-wide automation across a varied device estate. Its mix of version history, integrations, access controls, and a permanent 10-device free tier gives teams room to assess the product at small scale. Look elsewhere if you require air-gapped operation without an Unlimited license, or if a cloud-first deployment is essential.
