WebMomentvsShotLayer
ShotLayer helps developers generate Screenshots and OG images through an API. WebMoment preserves the Page and its visual context over time.
Preserved state
Open the Page Moment again later.
WebMoment keeps the historical Screenshot available after Capture, rather than treating it as only an output from one request.
Page context
Capture the favicon, OG image, and Metadata already on the Page.
Preserve the visual and descriptive context of the Page alongside responsive Screenshots.
Evolution
Build a record of how the Page changed.
New Captures extend the Timeline so your team can Compare versions and Share the visual history.
Generated OG images and preserved Page history serve different jobs
ShotLayer is useful for on-demand visual asset generation. WebMoment preserves the actual Page state, its favicon and OG image, its Metadata, and the sequence of future states.
