Showly is an app to display your slides to other people if you do not have large screens or projectors to show it easily. Showly desktop supports Linux and Windows, it has not been tested on MacOS yet.

When you run Showly desktop you will need to be connected to a LAN network, so your slides can be shared through that network. All participants of your talk will connect to the showly instance that is running on your pc using their web browsers on their pc or smartphones and they will see every single slide on it.

The following diagram shows how it would be:

To run Showly desktop you will need to have JDK 17 installed on your system. You can check if you have the correct JDK version running:

java --version

Then you have to download the latest version of Showly desktop from the releases page. Now, to run the program you have to open your Terminal in the same directory where you downloaded the showly app and execute the following command:

java -jar name_of_the_file_you_downloaded.jar

If you have configured your system to open .jar files, then you could open the program double clicking the .jar file.

if the participants of your talk are unable to see the slides on their web browsers you can try these things to fix the problem:

• Assert that the showly process is showing the slides.
• Check you are connected to the same LAN network as your participants.
• Assert the showly program is allowed through your firewall.
• Check the port you are using to run showly is allowed through your firewall.

Showly desktop is a GUI wrapper of showly package, so if you are a developer and want to make your own Showly GUI, you are able to do it wrapping that package as I did.
