Release Release activity Latest release Docker pulls Discourse posts License

As of January 8, 2024, Snowplow is introducing the Snowplow Limited Use License Agreement, and we will be releasing new versions of our core behavioral data pipeline technology under this license.

Our mission to empower everyone to own their first-party customer behavioral data remains the same. We value all of our users and remain dedicated to helping our community use Snowplow in the optimal capacity that fits their business goals and needs.

We reflect on our Snowplow origins and provide more information about these changes in our blog post here →


Snowplow is a developer-first engine for collecting behavioral data. In short, it allows you to:

Thousands of organizations like Burberry, Strava, and Auto Trader rely on Snowplow to collect, manage, and operationalize real-time event data from their central data platform to uncover deeper customer journey insights, predict customer behaviors, deliver differentiated customer experiences, and detect fraudulent activities.

Snowplow technology 101

Snowplow architecture

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.

About this repository

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 and as a historical artifact.

Components that have been extracted to their own repository are still here as git submodules.


A full list of supported trackers can be found on our documentation site. Popular trackers and use cases include:

Web Mobile Gaming TV Desktop & Server
JavaScript Android Unity Roku Command line
React Native Lua Android Go
Flutter React Native Java

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].
