Download GlassWire for Windows PC v3.11.1164 for Windows PC

GlassWire by SecureMix LLC is a visual network monitor and firewall front-end for Windows that graphs every connection your PC makes, alerts you to new...

Features

• The live traffic graph is exceptionally clear, letting you click any moment in time and see exactly which application connected to which host and how much data it used.
• Firewall control works through the built-in Windows Firewall, so blocking an application is simple and does not introduce a replacement firewall driver stack.
• Ask to Connect mode prompts you the first time a new application tries to reach the network, which makes silent background connections visible immediately.
• Built-in network scanning lists the devices on your local network and alerts you when a new device joins, which is useful for checking who is on your Wi-Fi.
• The free version is free forever rather than a timed trial, and since version 3.2 it no longer requires creating an account or signing in to use the Windows app.

Considerations

• The free tier keeps only 24 hours of network history, one day of bandwidth usage data and the current day's alert log, so longer investigations require a paid Premium plan.
• Several advanced monitors and controls, including longer history, fuller firewall management and unlimited remote connections, are reserved for Premium, which starts at $2.99 per month billed annually.
• GlassWire is Windows and Android only, requires Windows 10 or later in a 64-bit or ARM64 build, and dropped Windows 7, Server and 32-bit support after version 3.8.1061.

GlassWire's signature feature is a live, searchable traffic graph: every application connection is plotted over time, so you can click any spike and see exactly which app talked to which host, in which country, and how much data it moved — no packet-capture expertise required. The Traffic Monitor, GlassWire Protect and Log Analysis views build on that graph with per-app bandwidth totals and history. It answers a question most Windows users cannot answer today: what is my computer actually talking to, right now and last Tuesday? For spotting a bandwidth hog, a chatty updater or something that should not be phoning home at all, it is the friendliest tool of its kind. Version 3.11.1164, released in October 2026, added bulk allow, block and remove actions on the firewall list and improved GPU and memory tracking accuracy.

Unusually for a firewall product, GlassWire works through the built-in Windows Firewall rather than replacing it, so blocking an app is a low-risk one-click action instead of a leap of faith in a third-party driver stack. Ask to Connect mode prompts you the first time a new application tries to reach the network, which makes silent background connections visible immediately. The alerting side is equally practical and surfaces quietly instead of burying you in popups: first network activity from an app, changes worth knowing about, and a network scanner that lists the devices on your local network and notifies you when a new device joins — useful for checking who is on your Wi-Fi. GlassWire is built by SecureMix LLC for Windows 10 and later, in 64-bit and ARM64 builds.

GlassWire is free forever for basic monitoring, with no account required, but the free tier is deliberately time-limited: it keeps only 24 hours of network history, one day of bandwidth usage data and the current day's alert log, plus a single remote connection, so longer investigations require a paid Premium plan, which starts at $2.99 per month billed annually for the Personal plan and unlocks longer history, fuller firewall management and unlimited remote connections. That history limit is the real dividing line — it makes the free version a live monitor rather than an audit tool: if you need to investigate what happened last month, you will hit the paywall. It is also a monitor and firewall front-end, not an antivirus, so it complements rather than replaces endpoint protection. Platform limits are real too: Windows and Android only, and Windows 7, Server and 32-bit support were dropped after version 3.8.1061. On a supported PC it needs 2 GB of RAM and 250 MB of space.

Download the official GlassWire 3.11.1164 installer (EXE, about 118 MB) from glasswire.com using the download button on this page.

Open the downloaded EXE and follow the installation wizard; GlassWire installs its service and network driver, and a Windows Firewall prompt may appear during setup.

Launch GlassWire, watch the live traffic graph to see which apps are connecting, then open GlassWire Protect to allow or block apps and turn on Ask to Connect if you want a prompt for new connections.

Is GlassWire free for Windows?

Yes. GlassWire has a Free plan for basic network monitoring on Windows 10 or later, with no account required. The free tier is limited mainly by history: it keeps 24 hours of network history, one day of bandwidth data and the current day's alert log.

Is GlassWire any good?

Yes, if you want to see what your PC is connecting to. Its live, searchable traffic graph shows the app, host and timing behind a connection or bandwidth spike, and its firewall controls work through Windows Firewall. It is a monitoring and control tool, not an antivirus or a replacement firewall engine.

How much does GlassWire cost?

The basic Windows app is free. Premium starts with the Personal plan from $2.99 per month billed annually, which removes the free tier's short history limits and unlocks additional monitors and firewall controls.

What is GlassWire used for?

GlassWire is used to monitor network activity and manage application connections. It plots traffic by app, host and time, alerts you to new connections, shows bandwidth use, and lets you allow or block apps through the built-in Windows Firewall.
