Event Snapshots - a HAR alternative

Event Snapshots - Our alternative to Http Archives (HAR)

Quick link to comparison table: "Event Snapshot" vs. "Http Archive"

An Event Snapshot combines the network traffic and console output of a browser tab with an optional screenshot and the cookies of this tab plus some environmental data. WebSocket communication and Server-Sent-Events are covered as well.

You can use Events Snapshots to save and export what you are seeing when inspecting websites with the webQsee Analyzer.
The Analyzer allows you live-inspections of the network communication and the console output of a specific browser tab.
If you capture strange behavior of a web application during such an inspection, you can just create a "snapshot" of what you are seeing.

There is an intelligent selection of response bodies: images and text-based response bodies of network requests will be included in the snapshot, while other types of responses, that we couldn't display directly anyway, won't be included (like parts of streamed videos).
Even if a body is excluded, its http request and the request metadata (headers, ...) are still captured in the snapshot.

The data of Event Snapshots remains on your local system unless you explicitly export or sync it to somewhere else.
No data captured with webQsee leaves your system without your knowledge and your prior instruction to do so.
Even if you upload captured data to the Cloud Gallery, it will land on your own Cloud Storage.  In this case only non-critical metadata about the gallery items will be stored on webQsee servers, like the title, description or status of the item.

After creating or importing Event Snapshots, they can be found in your local webQsee Gallery.
You can view any snapshot listed in your gallery at any time.

Event Snapshots can be exported by clicking the download icon in the Gallery item and they can be imported through dragging and dropping them in the "Import" Tab of the Local Gallery or anywhere in the main webQsee window.
Exports and imports of Event Snapshots are free for everyone, even for users that do not have a webQsee account!
