Free, open-source IP address management (IPAM) and network inventory software for homelabs and small IT teams. Organise IPv4 subnets, track IP address allocations and reservations, document network devices, and manage equipment racks — all from a single HTML file. No database, Docker, container manager or server required.
Your infrastructure documentation, all in one place.
Ever wondered which IP addresses are free, which device is using a particular address, or how much space is left in your rack? Caffoot Lite brings those everyday infrastructure questions together in one easy-to-use tool.
Instead of juggling spreadsheets, handwritten notes and scattered records, you can organise IPv4 address blocks and subnets, document devices and IT assets, and see equipment positioned in visual rack elevations. A dashboard gives you a useful overview of your environment.
It's designed for home labs, enthusiasts and smaller IT environments that want clear records without setting up a complicated management platform.
Keep IP addresses organised
Track IPv4 networks, subnets, VLAN context, allocations and reservations.
Good to know: Lite stores data locally in your browser, not on a hosted account. Export JSON backups regularly; clearing browser data may erase your records. Lite has no built-in authentication, so it must not be exposed directly to the public internet.
Why Caffoot Lite?
Your infrastructure. Without the infrastructure.
No database. No Docker. No container manager. No server. No office suite. No account. The published release runs from one HTML file — just open it in a modern browser.
One file, ready to run
Download the published HTML application and open it locally. No installation or server configuration required.
Useful tools, no server needed
Document devices, IPv4 subnets, address allocations, reservations and racks without needing a constant internet connection.
Always free and open source
Caffoot Lite is built to remain accessible, portable and free — even as Caffoot Pro develops.
Powerful enough to be useful. Simple enough to just open. 🦔
IP address management
Free IPAM software without the complexity.
Managing IP addresses shouldn't require a dedicated server or complicated deployment. Caffoot Lite helps you document IPv4 networks, organise CIDR subnets, track assigned and available IP addresses, and manage reservations in one straightforward application that runs locally in your browser.
Designed for home labs and small IT teams, Caffoot Lite is a manual IP address management and network documentation tool — not an automatic network scanner, DHCP server or shared multi-user service.

Caffoot Lite
Simple tools. Less friction.
A lightweight way to organise infrastructure information, designed around straightforward workflows. Get the free Lite release from the official Caffoot GitHub repository.
Caffoot began as a Microsoft Access database application, built to solve a practical infrastructure management challenge for a client.
I wanted to take that idea further: make it responsive, straightforward to use and independent of office software. As someone who loves open-source software, I also wanted to create something that other people could use and build on.
That became Caffoot Lite — a free, open-source way to organise network and IT infrastructure. Lite will always remain free and available as a standalone HTML application.
It's also the foundation for Caffoot Pro, a planned Docker-based edition with more features. Pro is still in development, with no release date announced.
Human ideas. AI-assisted development.
Caffoot is shaped by a real-world need and developed with the help of modern tools, including AI-assisted coding. The ideas, direction and ongoing improvements are driven by its creator, with a focus on useful features, simplicity and continuous improvement.
Frequently asked questions
Good questions. Simple answers.
The essentials before you get started with Caffoot Lite.
Is Caffoot Lite really free?
Yes. Caffoot Lite is free and open source, and the plan is to keep it that way permanently. The source is published under the MIT licence; Caffoot's name and official branding have separate conditions.
Do I need Docker, a database or a container manager?
No. The published Caffoot Lite application runs from a single HTML file opened in a modern browser. You don't need Docker, a database, a web server, a container manager, Microsoft Access or an office suite.
Does Caffoot Lite work offline?
Yes. The standalone application is designed for local use, including without an internet connection. You can open the HTML file without running a server or signing in.
Where is my inventory saved?
Your devices, addresses, racks and settings are saved in your browser's local storage — not inside the HTML file, on a server or automatically in the cloud. Clearing browser data can permanently erase your inventory, and moving or renaming the HTML file may affect access to it.
How do I back up my data?
Use the built-in Settings & Data Management tools to export a JSON backup, and store it safely outside the browser. Always export and verify a backup before upgrading, changing browsers, moving the HTML file or resetting data. Backups can contain sensitive network information.
Can I put Caffoot Lite on a public web server for my team?
Caffoot Lite is intended primarily for local use, not as a public multi-user service. It has no built-in login, access control or shared server-side database. Do not expose it openly to the internet. Consult the repository's security guidance before considering any hosted deployment.
Does it automatically discover devices on my network?
No. Caffoot Lite is a documentation and inventory tool, not a network discovery scanner. You add and manage the infrastructure information you want to track.
What is Caffoot Pro?
Caffoot Pro is a planned Docker-based edition intended to build on Lite with additional capabilities. It's still in development; features, pricing and a release date haven't been announced. Lite will remain free and standalone.
For full instructions, upgrade precautions and security guidance, see the Caffoot Lite repository ↗.

Caffoot Lite — Free
Available now. IPAM, device inventory, asset tracking, racks and JSON backup/restore.
Document your IPv4 address space in one place, from larger address blocks and CIDR subnets to individual allocations and reservations. Keep a clear record of what is in use and what is still available.
Record IPv4 address blocks and CIDR subnets in a structured hierarchy, so you can see how your network space is divided and keep related networks together.
Track assignments
Document which addresses have been allocated or reserved. This makes it easier to check existing records before assigning an address to another device.
Keep VLAN context
Record relevant VLAN information alongside your network documentation, helping you understand how subnets and address allocations fit into your environment.

See both rack faces
View front and rear rack elevations to document devices and accessories on either face. Keep a clearer picture of how your rack is populated, not just what is visible from the front.
Document equipment placement
Record where devices and accessories are mounted within the rack. Clear placement records make it easier to find equipment, review layouts and plan changes.
Plan available space
Review occupied and available rack units before adding equipment. Visual rack layouts help you understand utilisation and plan future installations.

Your Caffoot Lite records are stored locally in your browser. Download a JSON backup to keep a separate copy of your inventory, and use the data management tools to restore a compatible backup when needed.
Create a portable JSON copy of your records using Settings & Data → Data Management → Download Backup. Store the file somewhere safe outside your browser.
Restore when needed
Use the data management tools to import a compatible backup, then check that the expected records are present. Read any confirmation prompts carefully before restoring.
Upgrade with care
Make a fresh backup before changing Caffoot Lite versions, switching browsers or clearing browser data. Browser storage alone is not a backup.
How to back up and restore your data
Backups are created manually. Save a copy outside your browser so you can recover your inventory if browser storage is cleared or you move to another computer.
Download a backup
Open Caffoot Lite.
Click Settings & Data.
Under Data Management, click Download Backup.
Save the downloaded backup file somewhere safe, ideally on a separate drive or trusted cloud storage.
Restore a backup
Open Caffoot Lite and go to Settings & Data.
Find the backup import or restore option under Data Management.
Select your compatible backup file and follow the on-screen prompts.
Check your inventory after the restore to make sure the expected records are present.
Check any confirmation prompts carefully before importing, particularly if you already have inventory stored in this browser.
