How it all began
For years, we’ve been pushing the boundaries of co-browsing and real-time web collaboration at Surfly. Along the way, we kept hearing the same thing from our most innovative customers:
"Your rewriting engine is so powerful… what if we could use it to reshape the web itself?"
That question sparked an idea—one that’s been quietly in the works. And now, we’re ready to share it with the world.
Introducing Webfuse, allowing you to unlock a new way to modify, automate, and enhance any website instantly—without touching its original code.
No plugins. No installs. No limits.
