Streamlit

Leading open-source Python framework for building data and ML web applications, now embedded within Snowflake's Data Cloud platform

Streamlit is an open-source Python framework designed to enable data scientists, machine learning engineers, and developers to rapidly build and deploy interactive web applications directly from Python scripts. Founded in 2018, Streamlit gained massive traction in the data science community by dramatically lowering the barrier to creating shareable, interactive data apps — eliminating the need for front-end web development skills. Its intuitive API allows users to turn data scripts into fully functional web apps in minutes, making it a go-to tool for prototyping ML models, building internal dashboards, and sharing analytical insights. Snowflake acquired Streamlit in March 2022 for approximately $800 million, integrating it into the Snowflake Data Cloud ecosystem. As a Snowflake subsidiary, Streamlit continues to operate as a distinct product and brand, now deeply integrated with Snowflake's platform through Streamlit in Snowflake (SiS), which allows users to build and run Streamlit apps natively within the Snowflake environment without data ever leaving the platform. This integration significantly expanded Streamlit's enterprise reach and security posture. While Streamlit is not an AdTech-native company, it is widely used within the AdTech and marketing analytics ecosystem for building internal reporting dashboards, campaign performance visualizers, audience segmentation tools, and ML model demos. Its open-source community remains highly active, and the product continues to evolve under Snowflake's stewardship, maintaining its free, open-source core alongside enterprise-grade deployment options.
