Trackers are client- or server-side libraries which track customer behaviour by sending Snowplow events to a Collector.
- JavaScript Tracker - for tracking user activity on websites and webapps
- No-JS Tracker - a pixel tracker for web environments where JavaScript is not available
- Lua Tracker - track events in your Lua-based applications, Lua web servers/frameworks, or from the Lua scripting layer within your games or apps
- Arduino Tracker - for tracking events from an IP-connected Arduino board
For other trackers (e.g. iOS, Android) and their approximate timelines, please see the Product roadmap.
- Snowplow Tracker Protocol - the protocol implemented by all trackers
