RackTables

RackTables is a free, self-hosted system for keeping datacenter hardware and network records together. It is best suited to teams that need detailed infrastructure documentation and rack-capacity planning without a software license fee. Its broad inventory model is balanced by volunteer-driven support and public-by-default bug reports.

Overview

RackTables ties physical assets to their rack locations and network records, so teams can document equipment, connections and addressing in one system. That makes it more useful for datacenter operations than a basic asset list, particularly when knowing where equipment sits and how it connects matters.

The application runs on-premises and is accessed through a browser with an internet connection. The project describes it as PHP software, and its homepage identifies version 0.22.0 as the latest stable release. Teams that want a hosted service should look elsewhere.

Key features

• Devices and rack capacity: Track devices, racks and enclosures, mount equipment, organize racks into rows, check free space and mark unusable rack units. This supports practical capacity planning, though it is oriented around documenting racks rather than a general inventory workflow.
• Network documentation: Manage IP addresses and networks, record NAT rules, and store load-balancing policies and configurations. Maintaining these alongside device records helps infrastructure teams keep physical and network context connected.
• Ports and links: Record device ports and the links between them, giving teams a way to document connectivity as part of the same inventory.
• Tags and attachments: Add files to system objects and apply flexible tags. Filtering rules can retrieve tagged hardware, which helps teams find relevant assets in a growing inventory.
• Permissions: User accounts can be granted or denied actions. This gives teams control over who can change records, while issue reports have a separate privacy consideration: they are public by default, with an option to make an issue private.

Pricing

RackTables is free software under GNU GPL version 2. Its Free software plan costs nothing, and no limits are stated. That makes it a fit for teams willing to operate an on-premises application without a software charge; it does not provide a paid support tier in the plan information.

Platforms

RackTables is web-based and deployed on-premises. Browser access suits teams that need to reach records from different locations, while the self-hosted model means the organization is responsible for running the application.

Who it's for

Choose RackTables if your team needs a free, detailed record of datacenter equipment, rack positions, available capacity and network configuration in one web application. It is less suitable for organizations that require hosted deployment or dependable, immediate support: the project relies on volunteers, and issue requests may not be dispatched promptly.

Pros and cons

• Pro: Physical inventory, IP records, network configuration and connectivity documentation sit together, reducing the need to split those records across separate tools.
• Pro: Rack rows, free-space checks and unusable-unit markings make it useful for tracking capacity as well as installed equipment.
• Pro: The GPL-licensed plan is free, with no limits stated.
• Con: On-premises deployment excludes teams seeking a managed hosted service.
• Con: Volunteer-driven issue handling may be slow, and bug reports are public by default unless changed to private.

Verdict

RackTables is a strong choice for teams that want a free, on-premises record of datacenter assets, rack capacity and network configuration in one place. Its central advantage is the connection between physical and network documentation; its main trade-off is relying on volunteer support, with bug reports public by default. Choose it when comprehensive records matter more than hosted convenience or assured response times.
