Best Free IT Asset Management Software – Tools That Work for MSPs

Most ITAM buyer's guides are written for single-company IT departments. MSPs have different requirements – you're tracking assets across dozens of clients, not one company. The ITAM software market hit $2.09 billion in 2025, but enterprise tools like ServiceNow aren't built for your budget or your workflows. These six free tools are.

Free ITAM Software Comparison

The three open-source tools – Snipe-IT, GLPI, and Ralph – have no asset caps and provide API access on day one. That's where the "free" label holds up long-term. Lansweeper and AssetTiger are genuinely useful starting points, but the free tiers are on-ramps to paid products, not permanent solutions.

What to Look for in Free ITAM Software (MSP Checklist)

Multi-tenant or entity separation. You're managing assets for multiple clients. If the tool can't separate Client A's laptops from Client B's servers, you'll spend more time on workarounds than the tool saves you. GLPI's multi-entity feature handles this natively. Others require tagging hacks or separate instances.

API access for RMM/PSA integration. Your ITAM tool shouldn't be an island. If it can't talk to your RMM (TacticalRMM, Datto, NinjaRMM) or your PSA (Autotask, HaloPSA, ITFlow), you're double-entering data. Look for a REST API at minimum.

Barcode and QR scanning. Field techs need to scan a sticker, not type serial numbers into a web form on-site. Snipe-IT and AssetTiger handle this well. Others require third-party integrations or don't support it at all.

License tracking per client. Software audits happen. When they do, you need to pull every client's license allocation in minutes, not hours. Tools that track licenses as a first-class object – not just a notes field – save you when compliance gets serious.

Self-hosting option. Some MSPs need data on their own infrastructure for compliance or client requirements. Open-source tools like Snipe-IT and GLPI give you that control. Cloud-only tools don't.

Scalability past 500 assets. A tool that works for 50 assets but chokes at 500 isn't free – it's a time bomb. Test with realistic volumes before you commit.

The 6 Best Free IT Asset Management Tools for MSPs

Snipe-IT

Snipe-IT is the default open-source ITAM tool for a reason. It's been around since 2013, it's actively maintained (v8 launched in early 2025 with PHP 8.2+ support and custom checkout fields), and it does the core job well – track hardware, manage licenses, handle check-in/checkout, generate reports.

Self-hosted Snipe-IT is free with no asset or user limits. The REST API is solid, which means you can pipe asset data into your RMM or PSA with some scripting. Barcode and QR label generation is built in, and the mobile-friendly interface works for field techs scanning equipment on-site.

The limitation for MSPs: no built-in multi-tenancy. You can use categories, locations, and companies to segment clients, but it's not true entity separation. For MSPs managing 10+ clients, this gets messy. Some MSPs solve it by running separate Snipe-IT instances per client – which works but multiplies your maintenance overhead.

Best for: MSPs wanting full control over their ITAM data with a self-hosted, open-source tool. Ideal if you have 1–10 clients and don't mind the multi-tenant workaround.

GLPI

If Snipe-IT is an asset tracker, GLPI is an ITSM platform that happens to include asset management. It bundles ITAM, helpdesk, change management, and license tracking into one system. GLPI 11 is the current major release, with the 10.0 branch still receiving security patches.

The MSP-relevant feature is multi-entity support. GLPI's entity system lets you create isolated environments for each client – separate assets, separate tickets, separate user permissions – within a single installation. This is genuine multi-tenancy, not a tagging workaround. For MSPs managing dozens of clients, it's the only free tool that handles this natively.

Pair GLPI with the GLPI Agent (formerly FusionInventory) and you get automated network discovery and inventory – devices are scanned and imported without manual entry. The plugin ecosystem adds features like project management, contracts tracking, and knowledge bases.

The trade-off is complexity. GLPI's learning curve is steeper than Snipe-IT. Initial setup takes hours, not minutes. The interface prioritizes function over form. And because it tries to do everything, you'll spend time configuring modules you don't need before you get to the ones you do.

Best for: Mid-size MSPs (50–200 clients) who want ITAM and ticketing in a single platform with true multi-tenant separation.

Ralph

Ralph is a CMDB, DCIM, and asset management system built by Allegro, Poland's largest e-commerce company. It's designed for data center and back office hardware – think rack layouts, network infrastructure, IP address management, and hardware lifecycle tracking.

For MSPs managing infrastructure-heavy clients – colocation facilities, on-prem server rooms, network equipment across multiple sites – Ralph fills a niche that Snipe-IT and GLPI don't cover well. The data center visualization tools let you map physical rack positions, power chains, and network topology. The CMDB tracks configuration items and their relationships, which matters when a switch failure cascades through a client's network.

Ralph is open source under Apache 2.0 and built on Python/Django. Allegro confirmed continued investment in the project through 2025, focusing on modernization and maintainability.

The limitation: Ralph is overkill for MSPs who primarily manage endpoints and user hardware. If your clients are small offices with laptops, desktops, and a couple of switches, Ralph's data center focus adds complexity without proportional value. It also has no built-in multi-tenancy for MSP-style client separation.

Best for: MSPs managing infrastructure-heavy clients – data centers, colocation, network-dense environments. Not the right pick for endpoint-heavy shops.

Lansweeper

Lansweeper isn't open source, but its free tier covers up to 100 assets with unlimited users and community support. What sets it apart is agentless network discovery – point it at a network range and it finds devices, pulls hardware specs, installed software, and OS details without installing anything on endpoints.

The discovery engine is Lansweeper's real value. It scans Active Directory, SNMP devices, Linux/Unix via SSH, and cloud environments. For MSPs doing initial site audits or onboarding new clients, this automates the "what do they actually have?" question that otherwise takes a tech a full day to answer manually.

Reports are strong too. You can generate software license compliance reports, warranty status overviews, and hardware lifecycle summaries out of the box. The paid Starter tier ($199/month, 2,000 assets) is reasonable if you outgrow the free cap.

The limitation: 100 assets goes fast. A single client with 40 employees might have 100+ assets when you count workstations, monitors, printers, phones, and network gear. You'll hit the cap within one or two clients. There's no API on the free tier, which limits integration with your MSP stack.

Best for: MSPs starting small who want powerful network discovery and may scale to paid. Great for client onboarding audits even if you use a different tool for ongoing tracking.

OCS Inventory

OCS Inventory is a lightweight open-source tool focused on one thing: automated hardware and software inventory through network scanning. It uses agents deployed on endpoints to collect hardware specs, installed software, and network configuration, then reports everything to a central server.

The MSP angle is its pairing with GLPI. OCS Inventory feeds discovered asset data into GLPI via a sync plugin, giving you automated discovery (OCS) plus full ITAM and helpdesk capabilities (GLPI). This combination is a well-established open-source pattern – OCS handles the scanning, GLPI handles the management.

OCS supports Windows, Linux, macOS, and Android agents. The deployment packages let you push agents via GPO or your RMM tool. IP discovery scans network ranges for devices that don't have agents installed – printers, switches, IoT devices.

The limitation: the web interface looks like it was designed in 2008, because it was. The UI is functional but dated, and the reporting isn't as polished as Lansweeper or Snipe-IT. Documentation is inconsistent, and community support is thinner than GLPI or Snipe-IT. OCS works best as a discovery engine feeding into GLPI, not as a standalone ITAM platform.

Best for: MSPs already running GLPI who need automated agent-based discovery across client networks.

AssetTiger

AssetTiger is the only cloud-hosted option on this list with a meaningful free tier – 250 assets, all core features included, no credit card required. It's not open source, but for MSPs who don't want to maintain a self-hosted application, it removes the infrastructure burden entirely.

Setup takes minutes. The interface is clean and modern compared to the open-source options. Barcode scanning works via mobile app (iOS and Android), maintenance scheduling sends alerts before warranties expire, and check-in/checkout tracking covers the equipment loan workflow most MSPs need.

Paid plans start at $120/year for 500 assets and scale to $3,025/year for 250,000 assets – reasonable if you outgrow the free tier. Unlimited users on all plans means you won't get hit with per-seat charges.

The limitation: no API access on the free tier, which means no automated integration with your RMM or PSA. You're manually managing data or paying to upgrade. It's also not open source – you can't self-host, inspect the code, or modify it. For MSPs with compliance requirements around data sovereignty, that's a non-starter.

Best for: Solo MSPs or small shops who want a functional ITAM tool running in five minutes without managing servers. Good for tracking physical assets (equipment, furniture, vehicles) that your RMM doesn't cover.

How to Choose the Right Free ITAM Tool for Your MSP

Skip the feature comparison spreadsheet. Start with three questions: how many clients do you manage, what kind of assets dominate your portfolio, and how much infrastructure management do you want to take on?

Solo or small MSP (under 50 clients, endpoint-heavy): Start with Snipe-IT. Self-host it on a $5/month VPS, use the companies feature to separate clients, and connect it to your RMM via the API. If you don't want to manage a server, AssetTiger's 250-asset free tier gets you started with zero infrastructure. You'll outgrow it, but it buys you time to evaluate what you actually need.

Mid-size MSP (50–200 clients, mixed assets): GLPI with the GLPI Agent for automated discovery. The multi-entity system scales to hundreds of clients without the per-instance overhead of running separate Snipe-IT installations. The learning curve is real – budget a weekend for initial setup – but the payoff is a single platform that handles assets, tickets, and license tracking across your entire client base.

Infrastructure-heavy MSP (data centers, colo, network-dense clients): Ralph for the DCIM and CMDB capabilities that general-purpose ITAM tools lack. Pair it with Snipe-IT or GLPI for endpoint tracking if you also manage user hardware.

Self-host vs cloud: If you're already running open-source RMM tools like TacticalRMM, adding a self-hosted ITAM tool is marginal overhead. If your stack is entirely cloud-based vendor tools, the maintenance burden of self-hosting might not be worth it – start with AssetTiger or Lansweeper's free tier and reassess in six months.

Not sure what combination fits your operation? The OpenMSP stack builder lets you map out your current tools and see where open-source alternatives drop in.

How Free ITAM Fits Into Your MSP Stack

ITAM doesn't exist in isolation. The value multiplies when asset data flows into the rest of your stack – your RMM knows what's online, your PSA knows who's paying for it, and your ITAM knows what it is, who owns it, and when the warranty runs out.

The open-source MSP stack pattern looks like this: TacticalRMM for remote monitoring and management, ITFlow or HaloPSA for ticketing and billing, GLPI or Snipe-IT for asset tracking, and Wazuh for security monitoring. Each tool handles its domain, and APIs stitch them together. No single vendor controls the whole picture – and no single price hike forces you to rethink everything.

The OpenMSP tool directory maps out every open-source tool available for MSPs by category – RMM, PSA, ITAM, backup, security, documentation. If you're evaluating your stack holistically, start there instead of tool-shopping one category at a time.

The MSPs cutting costs by 20–30% on tooling aren't doing it by finding one cheaper vendor. They're replacing three or four locked-in platforms with open-source alternatives that do the same job without the licensing math working against them every renewal cycle. Free ITAM is one piece of that – usually the easiest piece to start with, because the switching cost is close to zero when you're coming from a spreadsheet.

FAQ

What's the best free IT asset management software for MSPs?

It depends on your size and setup. For most MSPs, Snipe-IT is the strongest starting point – it's open source, self-hosted, has no asset limits, and provides a REST API for integrating with your RMM and PSA. If you need true multi-tenant separation across dozens of clients, GLPI is the only free tool that handles that natively.

Is Snipe-IT really free?

Yes. Snipe-IT is open source under the AGPL license. You can self-host it with unlimited assets and unlimited users at no licensing cost. The only costs are your server (a $5–10/month VPS works fine for most MSPs) and the time you spend on setup and maintenance. There's also a paid hosted version if you'd rather skip the server management.

Can I use free ITAM software for multiple clients?

You can, but not every tool handles it well. GLPI's multi-entity system is built for this – it creates isolated environments per client within one installation. Snipe-IT requires workarounds using the companies feature or running separate instances. Lansweeper and AssetTiger don't support multi-tenancy on their free tiers.

What's the difference between ITAM and RMM?

RMM (Remote Monitoring and Management) tracks what's online and lets you manage it remotely – patching, scripting, alerts. ITAM tracks the full lifecycle of an asset: who owns it, where it is, what it cost, when the warranty expires, and what software licenses are assigned to it. Your RMM knows a laptop is online. Your ITAM knows it belongs to Client B, was purchased in 2023, has an expiring warranty next month, and runs two licensed applications. Most MSPs need both.

How many assets can I track for free?

Open-source tools – Snipe-IT, GLPI, Ralph, and OCS Inventory – have no asset limits. You can track as many as your server can handle. Lansweeper's free tier caps at 100 assets. AssetTiger caps at 250. For MSPs managing more than a handful of clients, the open-source options are the only ones where "free" stays free at scale.
