Notable Nutanix Alternatives and Competitors 

Choosing and moving to a Nutanix alternative involves two distinct types of tooling: software that helps you plan and de-risk the migration by mapping what you actually run today, and the platforms you migrate onto. The tools below are grouped accordingly.

Infrastructure Mapping and Migration Tools

1. Faddom 

Faddom is an agentless application dependency mapping (ADM) and IT infrastructure discovery platform for on-premises, cloud, and hybrid environments. It discovers servers, applications, and the network traffic between them without installing agents on hosts and without storing credentials. Faddom builds and continuously updates topology maps, typically completing an initial map of an environment in under an hour. It uses AI-driven correlation to turn raw network traffic into application and dependency maps, and presents on-premises and cloud assets together in a single view. The platform is positioned for use cases such as data center and cloud migration, change management, asset documentation, and infrastructure security.

Key features include:

• Agentless, credential-free discovery: Faddom maps environments by observing network traffic and using protocols such as SNMP and flow data, rather than deploying per-host agents or storing privileged credentials. This reduces the deployment footprint and avoids ongoing agent and credential management across servers.
• Real-time application dependency mapping: The platform continuously discovers how servers and applications communicate, visualizing east-west traffic and the relationships between components. Maps update automatically as the environment changes, replacing static spreadsheets and point-in-time diagrams.
• Migration planning support: Faddom is used to scope migrations by surfacing the dependencies of each application, helping teams right-size target servers and anticipate move groups. This is intended to reduce the risk of unplanned outages when moving workloads between platforms or to the cloud.
• Documentation and CMDB feeds: The platform produces exportable diagrams and asset inventories and integrates with systems such as Jira Service Management and ServiceNow CMDB. This keeps configuration records aligned with the live environment for audit and compliance purposes.
• Impact analysis and change management: Faddom shows what a given server or application connects to, so teams can assess the potential impact of a change before making it. This supports change, release, and problem management workflows in complex environments.
• Security risk scoring and traffic monitoring: Faddom calculates a risk score that combines factors such as SSL status, known CVEs, user counts, and external traffic, and provides automated detection of abnormal traffic behavior on a continuous basis.

Limitations (as reported by users on G2):
