Say Goodbye to Buffering!

Finally! A video player designed for your convenience!

Why?

Many websites use video players designed for minimum functionality. It's much easier to slap a basic player on a website and call it a day. The result? Constant buffering and terrible UI. FastStream is here to fix that.

How?

FastStream will replace the default video player on websites with a modern, sleek, and fast video player designed for your convenience. With download acceleration and full video pre-buffering, you won't see a video buffer again.

What?

FastStream is a browser extension originally developed by Andrew as a side project in high school. Six years and many iterations later, FastStream is now available for everyone to use. No costs, no ads, no tracking.
