Trackers - collecting data from your own applications
Snowplow trackers are client- or server-side libraries that enable you to collect events from your own applications.
All Snowplow trackers have open-source licenses (Apache 2.0 License, except for the JavaScript tracker which is BSD 3-Clause License). You can find the source code for each tracker on GitHub, where possible.
The JavaScript tracker repository is a multirepository containing the Web (JavaScript and Browser), Node.js, and React Native trackers.
For tracking events from third-party applications, use our webhooks.
