Webfuse

Webfuse changes how a website behaves without touching its code. It is a web augmentation platform that lets you modify, share and audit interactions on any web application, with no code to write and nothing to install.

The platform sits as a middleware layer between users and the site they are visiting, so the original source stays untouched and you need no special permissions from the site owner.

In practice, developers can inject custom functionality into an existing page, change how an interface looks, and build automation workflows that run on top of sites they do not control.

Webfuse also covers collaboration and security uses, since the same layer that changes a page can record and review what happens on it.

Sharing a modified web session is part of the pitch, which suits teams that want to walk colleagues or customers through a process on a live site.

Its categories point to AI agents, copilots and customer service as typical uses for this kind of overlay.
