To compare Hexowatch screenshots over time, create a visual monitor for the page, choose whether to capture the whole page or a selected area, and set its check frequency and notifications. When Hexowatch detects a visual change, review the archived screenshots side by side. For wording or a specific data field, pair the visual evidence with the appropriate content or HTML-element monitor.
Set up a Hexowatch visual monitor
- Choose the page and comparison scope. Identify the exact URL. Monitor the whole page for broad layout or design changes; choose a selected screen area when you care about a particular component. Hexowatch documents both options on its visual-monitoring page.
- Enter the URL and preview the page. Check that the page and the area you intend to monitor are represented as expected.
- Configure checks and notifications. Set how often Hexowatch should check the page and choose notification channels. The walkthrough documents these setup choices, but the exact labels in the current account interface may differ.
- Start monitoring. Hexowatch says its visual monitor captures and archives screenshots when it detects visual changes.
Review and compare the archived screenshots
When a change is detected, compare the snapshots for the same URL and monitored scope. Check four things: which area changed, where it changed, what looks different, and whether the change matters to your question. For example, a shifted section or replaced image is visual evidence; it does not, by itself, establish why the change happened or whether it is meaningful.
Hexowatch describes archived snapshots as a way to compare changes over time. Its compliance use case also presents page snapshots as a historical record or audit trail. See Why we built Hexowatch and its legal and corporate compliance use case.
If you are monitoring a small component, selecting that region can keep the comparison focused on it rather than the rest of the page. That is a practical use of the documented region-selection option, not a guarantee that unrelated changes or alerts will be eliminated.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Choose the monitoring signal that matches the change
- Visual appearance: Use the visual monitor for layout, imagery, color, or other visible changes.
- Visible wording: Use Hexowatch’s separate content monitor when the question is whether text changed.
- A particular page value: Use HTML-element monitoring when you need to follow a specific field or element.
These are distinct monitoring use cases in Hexowatch’s feature descriptions. A screenshot can show what the page looked like, while a content or element monitor can help answer whether a text or data change accompanied the visual difference. Hexowatch discusses monitoring options in Advanced Monitoring and How to track important changes on websites.
What the comparison can and cannot tell you
A pair of screenshots provides visual evidence for the selected page or region at the times captured. The cited Hexowatch workflow does not specify a pixel-scoring method or guarantee that every detected difference represents an important change. Dynamic content can also make repeated captures look different; if the outcome is unclear, compare the same scope and use content or HTML-element monitoring for the precise wording or field in question.

Using the Hexowatch API for before-and-after evidence
A Hexowatch update article dated December 2, 2021 said users could retrieve monitor-change data through the API, including before-and-after screenshots. This is a dated product-update statement, not confirmation of current API behavior or limits. Consult current Hexowatch API documentation before building a workflow around it: Hexowatch Updates: More API features + platform improvements.
