Share your app

Now that your app is deployed you can easily share it and collaborate on it. But first, let's take a moment and do a little joy dance for getting that app deployed! 🕺💃

Your app is now live at that fixed URL, so go wild and share it with whomever you want. Your app will inherit permissions from your GitHub repo, meaning that if your repo is private your app will be private and if your repo is public your app will be public. If you want to change that you can simply do so from the app menu.

By default all apps deployed from a Teams or Enterprise workspace are private to the developers in the workspace, which means that others in your company won't be able to view them unless you give them explicit permission. You can grant permission either in your workspace or from the app itself.

Sharing private apps

Viewer auth allows you to restrict the viewers of your app using single sign-on (SSO), which means listing out the specified Gmail, G-Suite, and SSO-enabled email addresses and specified domains that your company uses.

For example, your company email may be susan@company.com but it's administered by Google (which means you go to mail.google.com or you use things like Drive and Google Sheets).

Google OAuth is enabled by default, so if your company uses Google, you're good to go. If you've configured SSO for your organization via ADFS, Azure, Okta, or generic SAML, you will also be able to add email addresses and domains which are administered by those services. Read here for how to enable SSO for your org.

Once you have added someone's email address to your app's viewer list, that person will be able to sign in via Google Single Sign-On or your organization-specific Single Sign-On and view your app. If they are already logged in with that account in their browser (the usual case for most people) then they will automatically be able to view the app. If they are not logged in, or they have not been giving access, then they will see a page asking them to first log in.

Tip

Having trouble granting access? Is a viewer having trouble logging on? See our troubleshooting section for help.

If you add an entire email domain, anyone with an email address which uses that domain will be able to view your app after authenticating themselves. For example, if "foo.com" is added to the list of allowed email domains, anyone with an email address that ends in "@foo.com" will be allowed to view the app.

From your deployed app you can easily add viewers from your developer console.

  1. Select "Manage app" in the lower right corner.

  2. Choose "Settings" from the menu.

  3. Add Viewers in Settings.

    You can choose to allow anyone from a domain, for example allowing "foo.corp" would allow anyone with an email from foo.corp. Or you can choose to allow only selected viewers based on their individual emails. Make sure to enter them as a line-separated list.

    Add viewers

You can also add viewers directly from your dashboard.

  1. Open settings for your app

    Navigate to the app you want to add viewer to and click the hamburger icon to select "Settings."

  2. Add Viewers in Settings

    Click on the "Viewers" section in the App Settings and in the text input area, provide a line-separated list of email addresses for the users you wish to grant viewer access to your app, or provide a line-separated list of allowed email address domains. Click "Save."

From your deployed app you can click on the "☰" menu on the top right and select 'Share this app' to post it directly into social media or to share with the community on the Forum. We'd love to see what you make and perhaps feature your app as our app of the month ❤️.

To help others find and play with your Streamlit app, you can add Streamlit's GitHub badge to your repo. Below is an example of what the badge looks like. Clicking on the badge takes you to, in this case, Streamlit's Face-GAN Demo.

Streamlit App

Once you deploy your app, you can embed this badge right into your GitHub README.md by adding the following Markdown:

[![Streamlit App](https://static.streamlit.io/badges/streamlit_badge_black_white.svg)](https://share.streamlit.io/[user name]/[repo name]/[branch name]/[app path])
push_pin

Note

Be sure to replace https://share.streamlit.io/[user name]/[repo name]/[branch name]/[app path] with the URL of your deployed app!

Inviting other developers is simple, just invite them to your GitHub repository so that you can code on apps together, and then have them log in to share.streamlit.io. If you are working as a team, you likely are already in the same repos, so skip step 1 and go straight to having them log into share.streamlit.io

Streamlit Cloud inherits developer permissions from GitHub, so when your teammates log in, they will automatically view the workspaces you share. From there you can all deploy, manage, and share apps together.

You can also collaborate with other developers by having multiple contributors pushing to the same GitHub repo. Whenever anyone on the team updates the code on GitHub, the app will also automatically update for you!

If you want to try out something new while still keeping your original app running, just create a new branch, make some changes, and deploy a new version of the Streamlit app.

Every deployed app has its Github source code linked in the "☰" menu on the top right. So if you are looking to understand the code of another Streamlit app, you can navigate to the GitHub page from there and read or fork the app.
