Snowplow sources overview
Snowplow supports a wide range of sources which send events to your Collector endpoint.
Snowplow tracker SDKs are client- or server-side libraries that enable you to collect events from your own applications. For tracking events from third-party applications, use webhooks.
If you use Snowplow CDI, a coding agent connected to the Snowplow MCP server can choose the right tracker for your application, add it, and check that the events arrive in your pipeline. For example: "Add Snowplow tracking to this app for the events in our tracking plan, and confirm they reach my development pipeline."
Install the Snowplow MCP server and skills in your coding agent, such as Claude Code, Cursor, or Codex, with npx plugins add snowplow/skills. In Console, the Snowplow Assistant has the same tools.
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.
All Snowplow trackers have open-source licenses (Apache 2.0 License, except for the JavaScript tracker which is BSD 3-Clause License).
