Free network inventory management software
Network inventory — devices, addresses, licences, cable runs — is a job open source does well for free, and one BSimple does not do at all. Here is the honest map of the free options and their hidden price.
The key facts
- The job: a live register of network devices — switches, servers, access points, IPs, firmware, licences — and their state.
- Free is real here: open-source network inventory and discovery tools are mature, and the free tier is the standard way in.
- The hidden price: discovery tools need credentials and access; the register needs a maintainer, backups and updates — free licence, owned operation.
- BSimple's boundary: this is the one aisle we stay out of — BSimple manages business stock, not IT estates. Network inventory in open source is the deeper read.

What network inventory software does
The job is a register that stays current: every device on the network — switches, routers, servers, access points, printers — with its address, firmware, licence and state, plus the relationships between them. Two tool styles cover it: discovery scanners that sweep the network and build the register automatically (agent-based or agentless, needing credentials and access), and manual registers — structured lists you maintain, with barcodes on the racks. Discovery is the reason the category exists; hand-built registers go stale the week after they are finished.
Free is genuinely the standard here. Open-source discovery and inventory tools are mature, community-maintained, and used by the same IT teams that could afford commercial alternatives — the free tier is not a crippled demo but the product. The open-source angle in depth covers the specific tools, and free computer-hardware tracking covers the asset-register cousin of this job.
The hidden price of free, in this aisle especially
- Access is maintenance. Discovery needs credentials, SNMP strings and firewall holes; every change to the network is a change to the scanner's access.
- The register needs an owner. Who reconciles what discovery found with what finance thinks was bought? A register without a name attached decays into archaeology.
- Backups and updates are yours. Self-hosted free tools mean self-managed patching and restores — the standard self-hosting trade.
- Coverage gaps are honest. Discovery finds what talks on the network; rooms full of unpowered spares and the cable between racks still need a human with a label gun.
None of this makes free the wrong choice — for IT estates it is usually the right one. It makes free a commitment rather than a gift.
Why BSimple is not on this list — plainly
We build BSimple, and it is business management software: one record of stock, orders, purchasing and invoicing for wholesale, manufacturing and distribution businesses — products that get sold, not devices that get maintained. It has no network discovery, no device registers, no licence tracking, and the honest thing this page can do is say so and point you to the aisle that fits: the open-source network inventory picture and the Reddit-view summary of open-source tools are the useful reads, and the free options there are genuinely good.
Where the two worlds touch is trivial and worth naming: if your business sells network hardware, that is stock — SKUs, quantities, suppliers, invoices — and that is what the inventory management pillar covers. Maintaining a network you own is a different job with different tools; the trial is for the selling side.
Frequently Asked Questions
Is there good free network inventory software?
Yes — open-source discovery and register tools are mature and standard in IT teams. The costs are operational: credentials to maintain, an owner for the register, and self-managed hosting. Free licence, owned operation.
Does BSimple do network inventory?
No — no discovery, device registers or licence tracking. BSimple manages business stock for businesses that sell products. This is a boundary, not a gap: the two jobs need different tools.
What is the difference between network and business inventory?
Network inventory tracks devices that support the business and mostly stay put; business inventory tracks goods that get bought, stored and sold. Different records, different lifecycles, different software.
Our company sells switches and servers — is BSimple for us?
If you sell them, yes — that is stock with suppliers, quantities and invoices, exactly BSimple's record. If you maintain them, the IT aisle fits better. The inventory management pillar shows the selling side.
What should an IT team pick first — discovery or a register?
Discovery, because a register built by hand starts dying the day it is finished. Then name the person who reconciles discovery against reality — the tool finds devices; the owner keeps the record true.
