Short answer: there is no GlassWire for Mac. GlassWire runs on Windows and Android only, and its team hasn’t posted an update about a Mac version since 2021. GlassWire does three jobs, and on a Mac a different app does each one best:
- See which apps use the network, and block them: Little Snitch, or LuLu if you want it free.
- Get alerted before you go over a data limit: PeakHour.
- Know when your internet is slow or dropping, and why: PeakHour.
What GlassWire does on Windows
GlassWire’s own site describes it as a network monitor and firewall. Its main features are:
- A live bandwidth graph you can click to see which apps caused the traffic
- Alerts when a new app connects to the internet for the first time
- A firewall built on the Windows Firewall API, with click-to-block, an “ask to connect” mode and profiles
- Data limit alerts before you go over your plan
- A network device scanner that alerts when devices join or leave, plus ARP spoofing and “evil twin” Wi-Fi alerts
- History: 24 hours on the free tier, unlimited on Premium
It doesn’t advertise latency, packet loss or router bandwidth monitoring.
Is a Mac version coming?
Probably not soon. GlassWire’s download page lists only Windows 10 or later. Its FAQ still says the team is “continuing to work on Mac and iOS versions”, but the staff posts on its GlassWire for MacOS forum thread tell a different story:
- 2020: “Apple recently made some MacOS changes that may make GlassWire for MacOS impossible.”
- April 2021: “Most of the user interface work is completed, but the backend work with the OS was wasted because Apple made unexpected changes.”
No staff member has posted there since April 2021, and no Mac version has shipped. Mac users still ask in that thread, most recently in November 2025.

Where GlassWire is better
If you have a Windows PC as well as a Mac, GlassWire is a good tool for it, and its free tier is generous. On any platform, its strengths are things PeakHour doesn’t try to do:
- Per-app visibility. Clicking a spike in the graph to see which app caused it is GlassWire’s signature feature. PeakHour can’t do that.
- Firewall. GlassWire can block apps and ask before a new app connects. PeakHour only monitors.
- Security alerts. ARP spoofing, look-alike Wi-Fi networks and new devices on your network.
On a Mac, Little Snitch covers the first two jobs best.
Where PeakHour is better
PeakHour answers a different question: “Is my internet connection working properly, and if not, where is it failing?”
- The whole network, not just one computer. PeakHour reads bandwidth from your router (UPnP or SNMP), so the TV, phones and other computers count too.
- Data caps for the whole connection. Monthly usage tracking against your ISP’s quota and billing day, with alerts before you reach it.
- Connection quality over time. Latency, jitter and packet loss, recorded all day, so you can see what “the internet was bad last night” looked like.
- Where the problem is. Hop-by-hop monitoring shows whether a slowdown starts on your Wi-Fi, your router or your ISP.
- Outage alerts when the connection drops and again when it comes back.
- A native Mac app on the Mac App Store.
Which should you choose?
- You want GlassWire’s per-app graph and firewall on a Mac: get Little Snitch, or LuLu if you want a free firewall.
- You used GlassWire mostly for data limits, or to keep an eye on your connection: get PeakHour.
- You want both: run Little Snitch or LuLu for apps and PeakHour for the connection. They don’t overlap and don’t conflict.

FAQ
Is there a GlassWire for Mac?
No. GlassWire's download page lists Windows 10 or later only, and it also makes an Android app. GlassWire staff said in 2020 and 2021 that changes Apple made to macOS might make a Mac version impossible, and staff haven't posted an update on the forum thread since April 2021.
What is the closest Mac app to GlassWire?
For GlassWire's per-app traffic graph and firewall, Little Snitch is the closest match. LuLu is a free, open-source firewall, and Radio Silence is a simpler $9 option. For GlassWire's data usage alerts and an always-on view of your internet connection, use PeakHour. Many people run one of each.
Can PeakHour block apps like GlassWire's firewall?
No. PeakHour monitors and doesn't block connections. For blocking, use Little Snitch, LuLu or Radio Silence alongside it.
Can PeakHour show which app is using my bandwidth?
No. PeakHour shows bandwidth for your Mac, your router and other devices, not for each app. To see traffic per app, use Little Snitch, Radio Silence or Activity Monitor's Network tab.
Can I set a data usage limit with alerts on a Mac, like GlassWire's data limits?
Yes, with PeakHour. You set a monthly quota and the day it resets, and PeakHour sends a notification or an email at the thresholds you choose. It can count your whole network's usage from your router, not just your Mac's.
How much does GlassWire cost compared with PeakHour?
GlassWire has a free tier with 24 hours of history. Premium is listed at $2.99 a month, billed annually. PeakHour is $19.99 a year or $59.99 for a lifetime license on the Mac App Store, and there's a 7-day free trial.
