Start Screen Shares Directly From Slack Using Screenleap’s New Slack Integration

Slack is a popular tool that lets you chat with your team. If you use Slack, you’ll be excited to learn that our new integration will make Slack even more useful by allowing your team members to start a screen share directly from within Slack by simply typing “/leap” into any Slack channel.

How It Works

Slack offers a number of commands that you can type into the input box to enable additional functionality. Our integration adds a “/leap” command that you can use to start a screen share directly from within Slack.

You can configure the command by adding additional keywords after the command. Our “/leap” command supports the following keywords:

  • /leap – Share your browser window to a private URL.
  • /leap screen – Share your entire screen to a private URL.
  • /leap broadcast browser – Share your browser window to your personal URL.
  • /leap broadcast screen – Share your entire screen to your personal URL.

You’ll need to use the Chrome web browser in order to share your screen, but your screen share is viewable by anyone using a device with a web browser, including smartphones and tablets.

Once your screen is shared, the share link will be automatically inserted into your current Slack channel. Your team members will be able to view your screen by simply clicking on the share link.


To add the Screenleap integration to your Slack account, simply click on the “Add to Slack” button below:

Add to Slack

That’s it! Now everyone on your team will be able to use the “/leap” command to start a new screen share.


The first time you use the Screenleap slash command, you’ll be shown a link that you can click on to install the Screenleap browser share extension (if it’s not already installed).


Click on the link to 1) install the browser extension and 2) create a new account (it’s free!) or sign into your existing Screenleap account. The Free Account gives you 1 hour of free sharing per day (2 hours for people in education). Your screen share will automatically start after the installation completes.


As part of the installation, a green screen icon will be added to your Chrome address bar. When you’re ready to stop your screen share, simply click on the green screen and then click on the “Stop sharing” button.

Get In Touch

We hope you enjoy the new Slack integration. If you have any questions about the integration or want to learn more about Screenleap, please contact us. We’d love to hear from you!

Plugin Support Disabled In Latest Version Of Google Chrome

To allow you to share from as many computers as possible, Screenleap offers you multiple ways of sharing your screen. We offer a Windows app, a Mac app, a Java applet, and a browser extension. Sharing your screen using the Chrome browser, however, has become more limited starting with version 42 of Chrome as Google has decided to disable support for the NPAPI plugin that our Java applet depends on. As a result of this change, you will no longer be able to share your screen using the Java applet if you are using the Chrome browser.


To work around this issue, we have switched all Java applet users over to the Screenleap for Windows and Screenleap for Mac apps. As an alternative, you can also use our Screenleap browser extension, which now supports full-screen sharing. If you using Firefox or Internet Explorer, you can switch back to using the Java applet by doing the following:

  1. After signing in to the Screenleap site, move your cursor over the “Account” link on the top-right corner of the page and click on the “Settings & Preferences” link.
  2. Select “Java applet” for the “Share your screen using” option.
  3. Save your settings and then start a new screen share.

Re-Enabling the Java NPAPI Plugin

If you are having problems getting the Screenleap for Windows app working for any reason, you can temporarily re-enable support for the Java applet plugin by first following the steps above to switch back to using the Java applet and then doing the following:

  1. Go to: chrome://flags/#enable-npapi
  2. Click “Enable” for “Enable NPAPI” option.


Please be aware that this option will only work for the next few months as Google plans to completely remove support for all plugins (including the Java applet plugin) in September.

Please contact us if you need any assistance with using the alternative presenter apps or re-enabling the Java applet plugin temporarily.
