Snowplow is a developer-first engine for collecting behavioral data. In short, it allows you to:
- Collect events such as impressions, clicks, video playback (or even custom events of your choosing).
- Store the data in a scalable data warehouse you control (Amazon Redshift, Databricks, Elasticsearch, Google BigQuery, Snowflake) or emit it via a stream (Amazon Kinesis, Google PubSub, Kafka).
- Leverage a wide range of tools to model and analyze the behavioral data: dbt, Looker, Metabase, Mode, Streamlit, Superset, Redash, and more.

|Snowplow Open Source||Snowplow Behavioral Data Platform|
|Our Open Source solution equips you with everything you need to start creating behavioral data in a high-fidelity, machine-readable way. Head over to the Quick Start Guide to set things up.||Looking for an enterprise solution with a console, APIs, data governance, workflow tooling? The Behavioral Data Platform is our managed service that runs in your AWS or GCP cloud. Check out Try Snowplow.|
The documentation is a great place to learn more, especially:
- Tracking design — discover how to approach creating your data the Snowplow way.
- Pipelines — understand what’s under the hood of Snowplow.
Would rather dive into the code? Then you are already in the right place!
The repository structure follows the conceptual architecture of Snowplow, which consists of six loosely-coupled sub-systems connected by five standardized data protocols/formats.
To briefly explain these six sub-systems:
- Trackers fire Snowplow events. Currently we have 15 trackers, covering web, mobile, desktop, server and IoT
- Collector receives Snowplow events from trackers. Currently we have one official collector implementation with different sinks: Amazon Kinesis, Google PubSub, Amazon SQS, Apache Kafka and NSQ
- Enrich cleans up the raw Snowplow events, enriches them and puts them into storage. Currently we have several implementations, built for different environments (GCP, AWS, Apache Kafka) and one core library
- Storage is where the Snowplow events live. Currently we store the Snowplow events in a flat file structure on S3, and in the Redshift, Postgres, Snowflake and BigQuery databases
- Data modeling is where event-level data is joined with other data sets and aggregated into smaller data sets, and business logic is applied. This produces a clean set of tables which make it easier to perform analysis on the data. We officially support data models for Redshift, Snowflake and BigQuery.
- Analytics are performed on the Snowplow events or on the aggregate tables.
For more information on the current Snowplow architecture, please see the Technical architecture.
To make sure all the components work well together, we strongly recommended you take a look at the compatibility matrix when setting up a Snowplow pipeline.
This repository is an umbrella repository for all loosely-coupled Snowplow components and is updated on each component release.
Since June 2020, all components have been extracted into their dedicated repositories (more info here) and this repository serves as an entry point for Snowplow users, the home of our public roadmap and as a historical artifact.
Components that have been extracted to their own repository are still here as git submodules.

This repository also contains the Snowplow Public Roadmap. The Public Roadmap lets you stay up to date and find out what's happening on the Snowplow Platform. Help us prioritize our cards: open the issue and leave a 👍 to vote for your favorites. Want us to build a feature or function? Tell us by heading to our Discourse forum 💬.
We want to make it super easy for Snowplow users and contributors to talk to us and connect with one another, to share ideas, solve problems and help make Snowplow awesome. Join the conversation:
- Meetups. Don’t miss your chance to talk to us in person. We are often on the move with meetups in Amsterdam, Berlin, Boston, London, and more.
- Discourse. Our forum for all Snowplow users: engineers setting up Snowplow, data modelers structuring the data, and data consumers building insights. You can find guides, recipes, questions and answers from Snowplow users and the Snowplow team. All questions and contributions are welcome!
- Twitter. Follow @Snowplow for official news and @SnowplowLabs for engineering-heavy conversations and release announcements.
- GitHub. If you spot a bug, please raise an issue in the GitHub repository of the component in question. Likewise, if you have developed a cool new feature or an improvement, please open a pull request, we’ll be glad to integrate it in the codebase! For brainstorming a potential new feature, Discourse is the best place to start.
- Email. If you want to talk to Snowplow directly, email is the easiest way. Get in touch at [email protected].
