Deploy an app
Streamlit Cloud lets you deploy your apps in just one click, and most apps will deploy in only a few minutes. If you don't have an app ready to deploy, fork or clone one of our example apps — you can find apps for machine learning, data visualization, data exploration, A/B testing and more.
Add your app to GitHub
Streamlit Cloud launches apps directly from your GitHub repo, so your app code and dependencies need to be on GitHub before you try to deploy the app. See App dependencies for more information.
Deploy your app
To deploy an app, click "New app" from the upper right corner of your workspace, then fill in your repo, branch, and file path, and click "Deploy". As a shortcut, you can also click "Paste GitHub URL".
Advanced settings for deployment
If you are connecting to a data source or want to select a Python version for your app, you can do that by clicking "Advanced settings" before you deploy the app.
Watch your app launch
Your app is now deploying and you can watch while it launches. Most apps take only a couple of minutes to deploy, but if your app has a lot of dependencies it may take some time to deploy the first time. After the initial deployment, any change that does not touch your dependencies should show up immediately.
The Cloud logs on the right hand side are only viewable to the developer and is how you can grab logs and debug any issues with the app. Learn more about Cloud logs.
Your app URL
That's it — you're done! Your app now has a permanent URL that you can share with others. Click here to read about how to share your app with viewers.
App URLs follow a standard structure based on your GitHub repo:
https://share.streamlit.io/[user name]/[repo name]/[branch name]/[app path]
If your app has name
streamlit_app.py and your branch is
master, your app is also given a shortened URL of the form
https://share.streamlit.io/[user name]/[repo name]. The only time you need the full URL is when you deployed multiple apps from the same repo. So you can also reach the example URL above at the short URL https://share.streamlit.io/streamlit/demo-self-driving.
