How it works

In the current version, you can share your screen, window, tab, or multiple files. This app uses Socket.io to manage some metadata for peers and files. The data is shared directly between peers without a server in the middle. All direct peers share the same stream or downloaded files to increase your audience and overcome limitations.

This is achieved using the WebRTC standard. A Google STUN server is used to establish connections between peers, but you can use your own STUN server if you host the app yourself. All metadata in this app is temporary and will be lost if the server restarts.

Limitations

The main limitation is your upload speed, which is shared with your direct peers. If you are streaming, factors like the codec, resolution, and quick refreshes can increase your CPU (for VP8/VP9) or GPU (for H.264) load and affect your upload speed. The Chrome browser can handle up to 512 data connections and 56 streams.

If you are sharing files, the file size and the number of files increase your memory usage. The files are splitted in chunks and your peers share also your downloaded file and hold the data in their memory.
