The short version

  • Each has a real cost: HWiNFO the free build is licensed for personal use only, so an IT department running it on employee machines is out of compliance and needs the paid edition.; Syncthing synchronisation, not backup: a deletion propagates to every device, and versioning must be configured deliberately
  • They diverge on capability: HWiNFO covers Sensor coverage, Syncthing covers Peer-to-peer sync.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

HWiNFO

  • The free build is licensed for personal use only, so an IT department running it on employee machines is out of compliance and needs the paid edition.
  • It is Windows only, so mixed estates need a separate tool for macOS and Linux hardware diagnostics.
  • It reports single machines rather than fleets, with no central console, so it answers a diagnostic question instead of monitoring an estate.
  • The volume of sensors displayed is overwhelming without hardware knowledge, and readings with similar names measure genuinely different things, which leads to wrong conclusions.
  • Sensor access requires a kernel-level driver and administrator rights, which anti-cheat systems and some hardened endpoint configurations block outright.

Syncthing

  • Synchronisation, not backup: a deletion propagates to every device, and versioning must be configured deliberately
  • Devices must be online simultaneously to sync, so an always-on machine is effectively required
  • Initial setup involves exchanging device IDs and is less approachable than signing into a cloud service
  • No web access to files, since there is no server holding them

Both have a free tier, so you can try either at no cost before committing.
What is HWiNFO best used for?
HWiNFO is most often used for diagnosing thermal throttling or power limits on a laptop or workstation under real workloads, validating that a new cooler, thermal paste or fan curve changed anything measurable, logging sensor data across a long stress test to identify what preceded a crash, confirming exactly which hardware revision is inside a machine before ordering more of them. Of those, diagnosing thermal throttling or power limits on a laptop or workstation under real workloads and validating that a new cooler, thermal paste or fan curve changed anything measurable are not what Syncthing is typically brought in for.

Answered from the vendors’ own pages

HWiNFO: Can I use the free version at work?

No. Free use is personal only. Any business use, including internal IT diagnostics, requires the paid licence.

Syncthing: Is Syncthing free?

Yes, open source with no licence fee and no storage costs, because there is no server.

HWiNFO: Does it run on macOS or Linux?

No. It is Windows only; the older DOS builds are discontinued.

Syncthing: Is Syncthing a backup tool?

No. It synchronises, so deletions propagate. Use it alongside a real backup, not instead of one.

HWiNFO: Why do temperatures differ from the motherboard utility?

Because vendor tools usually show one averaged figure while HWiNFO reports each sensor separately. The difference is labelling and selection, not accuracy.

Syncthing: Do my files pass through anyone else’s servers?

No. Transfers are peer to peer and encrypted. Discovery and relay servers can help devices find each other, and relayed traffic remains encrypted end to end.

HWiNFO: Is it safe to run alongside other monitoring tools?

Usually, but several tools polling the same sensors through their own drivers can cause conflicts and bad readings. Run one at a time when the numbers look wrong.
