Build with Streamlit
Write Streamlit apps in Python that show Snowflake data to the people who use it.

Overview
Your data should do more than sit in tables. Here you put an app on top of it.
Data Application Builders is Badge 3 of Hands-On Essentials, a free workshop where you build end-user apps on Snowflake. You use Streamlit, Python, GitHub and REST APIs, growing a project from a menu display to a capstone app with named stages. No prior coding is needed, but you work without step-by-step help, and Snowflake expects six months of use or Badges 1 and 2.

What it covers
Learn all the way down.
Learn all the way down.
Perform when it matters.
Run apps inside Snowflake
Use Streamlit in Snowflake, and work with internal named stages for files the app needs.
Connect GitHub and APIs
Bring GitHub and REST APIs into the app so it can use outside services and a real code workflow.
Finish a capstone
Combine the skills into a capstone project, working from a simple menu up to a data-driven interface.
Course outline
From a menu on a page
From a menu on a page
to a data app people use.
We design this course ourselves. Snowflake issues the credential, and LUNARTECH is independent of Snowflake.
A data app starts as a script that draws a page. You learn how Streamlit runs your code, add widgets and layout, show text, tables and charts, and read Snowflake data into the page.
- What Streamlit is and how a page runs
- Widgets and layout
- Showing text, tables and charts
- How an app remembers between clicks
- Reading Snowflake data into the page
You build A one-page Streamlit app that shows a Snowflake table and a chart with one filter.
Real apps take input, stay fast and fail politely. You add forms, cache expensive work, split an app into pages, handle errors for the user, and keep the code organized enough to change later.
- Forms and user input
- Caching to keep apps fast
- Multiple pages and navigation
- Handling errors for users
- Organizing app code
You build A multi-page app with a form, cached queries and friendly error messages.
Apps are most useful where the data already is. You create Streamlit apps in Snowflake, query through the active session, understand which role the app runs with, and share the result with the right people.
- Where a Streamlit in Snowflake app runs
- Queries through the active session
- Roles and access for an app
- Packages available inside Snowflake
- Creating and sharing an app
You build An app running in Snowflake that is shared with one role and sees only that role’s data.
Apps need more than tables: images, lookup files and configuration. You create internal named stages, upload and list files, read them into the app, and control who may reach them.
- What a named stage holds
- Uploading and listing files
- Reading files into an app
- Images and other assets from a stage
- Permissions on stages
You build An app that loads its images and a lookup file from an internal named stage.
Code that lives only in a worksheet is easy to lose. You keep app code in GitHub, work with commits, branches and pull requests, connect the repository to Snowflake, and keep secrets out of it.
- Why app code belongs in a repository
- Commits, branches and pull requests
- Connecting a repository to Snowflake
- Deploying from the repository
- Keeping secrets out of the repository
You build An app deployed from a GitHub repository, with a change made through a pull request.
Much useful data lives behind a web service. You make API requests, read JSON replies, handle keys and secrets properly, allow outbound calls safely, and decide what to store in Snowflake.
- What a REST API is
- Making requests and reading JSON
- Keys, secrets and authentication
- Allowing outbound calls from Snowflake
- Rate limits and failures
- Storing API data in tables
You build An app that pulls data from a public API and saves selected fields to a table.
You build one app that uses everything so far. It starts as a simple menu and grows into an interface driven by Snowflake data, files and an outside API, with the code kept in a repository.
- Planning the app from a user need
- Building the menu and the first view
- Adding data, files and an API
- Polishing and testing
- Showing the finished work
You build A finished data-driven app with a menu, stage files, an API feed and its code in GitHub.

Reviews
Real stories from the community.
LUNARTECH Academy has been the most empowering learning experience of my life, giving me a clear, structured path from the absolute basics to building real-world AI systems with confidence.
Your page is fantastic. As a bachelor’s student in Data Science now accepted for a master’s at UConn, your work has been a real source of motivation.
The programme’s clear, bite-sized content and practical projects dramatically improved my speed from fuzzy idea to MVP and my ability to communicate AI value. I followed the system, and it works.
I really appreciate your teaching style and the way you break down complex topics. It has been incredibly helpful.
After years working mainly with R for econometrics, I found your Python machine learning course a refreshing and engaging way to learn Python.
As a Data Science graduate, I want to thank you for the effort you put into making videos to support growing data scientists.
I’ve been following your work since taking your machine learning course, and I’m impressed by your practical approach to applying AI.
