Freshworks now owns Device42. Here is how NetBox, Sunbird, Nlyte, Hyperview, EasyDCIM and FluxBilling compare on discovery, rack and power, billing and published price.
Mario Marin12 min readThe strongest Device42 alternatives in 2026 are NetBox for a free, open-source source of truth; Sunbird dcTrack, Nlyte and Hyperview for enterprise DCIM focused on power and facilities; and EasyDCIM or FluxBilling for hosting providers that bill customers for racks, servers and IP addresses. None is a like-for-like replacement for Device42’s discovery and application dependency mapping, so start from the job you need done.
How this was sourced. FluxBilling publishes this page and sells billing software for hosting providers with DCIM built in, so it competes with some of the tools below. Every third-party fact and price was read from the vendor’s own site, filing or repository on 12 October 2026, in the currency each vendor publishes — no exchange rate is applied anywhere. Where a vendor publishes no price, we say so rather than estimate one.
Part of the FluxBilling guide to DCIM software for hosting providers. For the wider twelve-tool roundup, see the best DCIM software compared.
Device42 belongs to Freshworks, the company behind the Freshservice service desk. Freshworks signed the merger agreement on 30 April 2024 at an aggregate $230 million on a cash-free, debt-free basis — $215 million in cash plus a $15 million equity rollover by founder Raj Jalan and his affiliates, per its SEC filing — and completed the deal on 6 June 2024.
In February 2025 Freshworks launched Advanced ITAM “powered by Device42” inside Freshservice, and on 2 April 2026 it announced discovery and dependency mapping native to Freshservice ITAM, sold with Freshservice or standalone. Device42 is still sold under its own name, with a free trial and weekly live demos.
Its strengths, by its own description: agentless discovery from mainframes to cloud containers, application dependency mapping, a CMDB kept current by that discovery, and IPAM. The DCIM module adds room layouts, rack elevations that handle half-U and half-depth devices, patch panels, power monitoring over SNMP from PDUs, UPSs and cooling units, and thermal monitoring. Pricing is an annual subscription by device count, with no public price on 12 October 2026.
The alternatives split cleanly by who is buying.
In the first group, the enterprise tools are your shortlist and FluxBilling is not on it. In the second, discovery depth matters less than the join between a rack unit and an invoice line.
Only what each vendor states on its own pages; “none stated” means we found nothing, not that it is missing.
| Tool | Best for | Discovery | Rack and power | Billing link | Published price (read 12 Oct 2026) |
|---|---|---|---|---|---|
| Device42 | Enterprise hybrid IT feeding ITSM | Agentless, plus application dependency mapping | Room layouts, rack elevations, SNMP power monitoring, thermal monitoring | None stated; feeds Freshservice and other service desks | No; annual subscription by device count |
| NetBox | Network teams who script their own automation | Not in the open-source core; NetBox Discovery is a separate agent-based product | Rack elevations and power modelling; no monitoring | None stated | Community edition free (Apache-2.0); Cloud Free plan up to 100 devices; paid plans on quote |
| Sunbird dcTrack + Power IQ | Facilities and data centre operations | Auto-discovery of facility items such as PDUs and UPSs | 3D cabling, power-circuit tracking, environmental sensors, outlet control | Lists energy billback to customers; no invoicing described | $19.50/cabinet/mo (dcTrack), $5.50/node/mo (Power IQ), $27.50/cabinet/mo (suite); US only, USD |
| Nlyte | Large enterprise and colocation estates | Imports spreadsheets, barcode scans or discovery files | Power-chain capacity planning, space and cooling | Captures customer usage to support usage-based billing | No; quote only |
| Hyperview | Cloud-hosted DCIM with a public price | Agentless asset auto-discovery | Power and environmental monitoring, power-path dependency map | None stated | $3 per asset per year, 500-asset minimum (USD; GBP and EUR in the UK and EU) |
| EasyDCIM | Dedicated-server and colocation providers | Network auto-discovery, SNMP and IPMI | Locations and racks; PDU management from the $299 plan | Through WHMCS or HostBill integration | $69–$799/mo for 50–1,000 devices; colocation $49–$299/mo for 25–300 services |
| FluxBilling | Hosts that invoice customers for racks, servers, power and IPs | Per-device fetch over IPMI/Redfish and SNMP; no network scan | Visual rack editor, power budget per rack, PDU load polled every five minutes | Built in: same database as invoices | €4.95–€25/mo; US accounts $5.95–$29/mo |
They solve opposite problems. Device42 discovers what is actually running. NetBox documents what should be running: its documentation calls it the desired state of the network rather than the operational state, discourages importing live state automatically, and lists network monitoring and facilities management among the things NetBox is not.
NetBox wins on cost and community. The community edition is free under Apache-2.0, version 4.7.2 shipped on 29 September 2026, and the repository had about 21,700 GitHub stars on 12 October 2026. NetBox Labs sells NetBox Cloud and Enterprise on quotes, offers a free hosted plan for up to 100 devices and 500 IP addresses, and sells NetBox Discovery, an agent-based product that closes part of the discovery gap.
Choose NetBox if a network team will own it and build automation around it; choose Device42 if you need discovery and dependency mapping out of the box. The older free tools, openDCIM (last release 23.04, October 2023) and RackTables (0.22.0), still suit a small server room; all five open source options are compared in open source DCIM software in 2026.
Sunbird publishes US prices: dcTrack for asset, capacity and change management at $19.50 per cabinet per month, Power IQ for power and environmental monitoring at $5.50 per node per month, and both as a suite at $27.50 per cabinet per month. Perpetual licences are quoted, and there is a 30-day trial with your own data. Its feature list runs deep on power — circuit tracking, failover analysis, three-phase balance, outlet control — and includes energy billback to customers. It is a facilities tool; it does not describe IT application discovery.
Nlyte’s site identifies it as a Carrier company. Its strengths are power-chain capacity planning, asset lifecycle and workflow, with more than 100 integrations into service desks, CMDBs and building-management systems. It also pitches to colocation operators: its colocation solution captures each customer’s power, space and other billable usage to support usage-based billing. Pricing is by quote only.
Hyperview is cloud-hosted DCIM with a public price: $3 per asset per year with a 500-asset minimum, so at least $1,500 a year, with GBP and euro options for the UK and EU. Agentless auto-discovery, power and environmental monitoring and a power-path dependency map are included, with a 30-day free trial. Racks, PDUs and sensors count as assets too.
If you sell dedicated servers or colocation, every tool above leaves the invoice to you. Two options join rack management software to billing.
EasyDCIM automates dedicated servers and colocation — provisioning, unattended OS installs, IPMI, network auto-discovery and usage collection — and hands billing to WHMCS or HostBill through ready-made integrations. Dedicated-server plans cost $69, $99, $299 and $799 a month for 50, 100, 300 and 1,000 devices; colocation plans $49, $149 and $299 for 25, 100 and 300 services; larger fleets are quoted. IP address management starts on the second tier, PDU management on the $299 dedicated plan. It is two products and a sync, but a well-trodden one; the EasyDCIM alternative page compares the approaches.
Disclosure: this is our product. FluxBilling is billing software for hosting providers and colocation operators with DCIM built in on every tier, in the same database as clients and invoices. What it does today:
What it does not do: scan your network for unknown devices, map application dependencies, run a CMDB, model cooling or track power per outlet. There is no Device42 or NetBox importer; inventory goes in through the Bulk Add grid and the hardware fetch fills in the specs. EasyDCIM has a dedicated importer.
Plainly: Device42’s discovery and application dependency mapping are far deeper than FluxBilling’s. FluxBilling reads the hardware you point it at; Device42 finds what you did not know you had and maps what depends on it. Sunbird, Nlyte and Hyperview have deeper power, cooling and environmental tooling and a longer enterprise DCIM pedigree, so if you run the building rather than sell space in it, they fit better. NetBox is free and has by far the largest community here — about 21,700 GitHub stars against openDCIM’s 366. FluxBilling is also pre-1.0 and younger than every commercial product in this list. It only makes sense if you bill customers for the capacity you track; if you do not invoice for racks, power, servers or IP addresses, its billing half is weight you do not need.
If you bill customers for racks, power and servers, FluxBilling plans start at €4.95 a month (US accounts $5.95) with DCIM on every tier and a 14-day refund — see pricing, or try the live demo first.
For enterprise IT, Hyperview, Sunbird dcTrack and Nlyte — or, if you already run Freshservice, Freshworks’ own Freshservice ITAM, launched with Device42 technology in 2025. For a free network source of truth, NetBox. For hosts that bill for capacity, EasyDCIM with WHMCS or HostBill, or FluxBilling with billing built in.
Freshworks, the maker of Freshservice. It agreed to buy Device42 on 30 April 2024 for $230 million on a cash-free, debt-free basis and completed the deal on 6 June 2024. Device42 is still sold under its own name.
Device42 is better at finding what is running and what depends on it. NetBox is better as a free, scriptable record of what should be running, and its documentation says it does not do monitoring. Pick on whether you need discovery or a source of truth.
Yes. NetBox’s community edition is free under Apache-2.0, and NetBox Labs offers a free hosted plan for up to 100 devices. openDCIM and RackTables are also free but release rarely. None includes Device42-style discovery.
There is no neutral measure, so test on your own data. Sunbird and Hyperview offer 30-day trials, Device42 has a free trial, NetBox Cloud Free removes the install, and FluxBilling has a live demo and a 14-day refund. Self-hosted NetBox also needs PostgreSQL and Redis.
