Interaction Middleware

Change or audit any web interaction with Surfly

Use Surfly’s Interaction Middleware to transform any web interaction without changing the original application.

Trusted by hundreds of companies and more than 200,000 users worldwide

Surfly’s Interaction Middleware sits in between a user’s browser and the webpage they’re visiting. It receives all the content that makes up the page and temporarily replicates it, giving you the ability to then share it with multiple participants (as seen in the animation below), while layering collaborative features on top of it (co-browsing, screen sharing, video chat, annotations, etc.), or even transform the entire experience, all without changing the original code.

Build your product on top of Surfly

We enable you to build new solutions on top of external applications. The core of our technology is our proxy solution consisting of an HTTP/WS network proxy and the in-browser JS/DOM sandbox.

This allows us to intercept all the inputs and outputs of any web application. By defining what happens in those interception points you can completely change your own application or any third party solution.

Great additional service to our company!

“It is so easy! No one has to download anything for us to connect and the steps needing to make the connection is simple. It has great features that make it easy to show multiple websites and even be able to show documents loaded in my computer. To be able to swap control of the cursor back and forth is also great, so the end user can feel a part of their own enrollment.”
