Event Tracking

Connect your preferred tools for advanced analytics and real-time AI agent decisioning, from data sources to ML and agentic frameworks.
Snowplow is the Customer Context Infrastructure that transforms raw behavioral data into real-time customer context for AI agents and advanced analytics.Data teams rely on Snowplow to collect and process event-level data in real time, delivering it to their warehouse, lake, or stream, without the engineering overhead of building data infrastructure. Product and engineering teams rely on it to power agentic AI systems, personalization, and fraud detection.
Define, track, validate, and manage granular customer behavioral data with control and accuracy.
Access a comprehensive SDK library for collecting behavioral data across any platform or environment, supported by tools for developers.
Quickly and easily implement accurate event tracking across sources with specialized developer tools.
Identify and resolve data quality issues before and in production, supported by in-production real-time alerting and bad data debugging.
Easily implement custom Snowplow tracking SDKs based on your data design with Snowtype. Reduce manual configuration and ensure data consistency with type-safe, inline documentation, reducing time spent writing custom code.
Enable developers to focus on business logic rather than manual tracking code
Generate type-safe tracking code for 10 trackers across web, mobile, and server, with runtime validation for the Browser tracker
Eliminate common data quality issues by generating strict tracking code upfront
Connect Claude Code, Cursor, Codex, or another MCP client to your Snowplow account with the Snowplow MCP Server. From one prompt, your coding agent proposes a tracking plan for your approval, creates the schemas, adds the Snowplow tracker to your app, and checks that test events pass validation.
Design events, entities, and schemas by describing what you want to measure
Find and fix failed events with an agent that reads the validation errors
Keep tracking plans as local files in Git and validate them with the Snowplow CLI MCP server
Easily inspect tracked event data in a development environment called Snowplow Micro. Developers can familiarize themselves with the data collected using Snowplow and set up automated tests, which test and debug builds that would break Snowplow event tracking.
Enable easier development environment testing
Receive, validate, and enrich events before production
Automate tests to help maintain data accuracy at every step
Ensure an event has passed validation according to rules codified in the corresponding schema using the Snowplow browser extension, Snowplow Inspector. Easily QA event tracking in real time to identify why an event is not appearing in your data warehouse or if the event has passed validation.
Validate your Snowplow event tracking code
Test, diagnose, and debug the data in real time
Enable detailed visibility by parsing HTTP requests into readable formats
Track customer behavior for up to two years with specialized cookie extension services that maintain tracking capabilities even in environments with browser limitations like Intelligent Tracking Prevention (ITP).
Generate and manage a unique browser identifier from the same IP as your main web application
Mitigate the impact of third-party tracking restrictions across Safari and iOS browsers
Enable more accurate marketing attribution, customer journeys, product analytics, and personalized recommendations
Event tracking records each action a person takes in your product, such as a page view, button click, video play, or purchase, as a timestamped event with details about who did it, what they did, and where. Snowplow collects these events from websites, apps, and servers, validates each one against a schema you define, enriches it, and delivers it to your warehouse, lake, or stream in real time.
Server-side tracking sends events from your backend, so ad blockers and browser privacy restrictions can't block them, which makes it the most reliable option for events such as purchases and sign-ups. Client-side trackers run in the browser or app and capture what only the interface sees, such as scrolling, clicks, and screen views. Snowplow supports both, and events from every tracker land in the same atomic events table, so you can use them together.
Snowplow has more than 20 open-source trackers covering web, mobile, and server-side code. On the web, there are the JavaScript and Browser trackers, Google Tag Manager templates, Google AMP, and a pixel tracker for email. For apps, there are iOS (including macOS, tvOS, watchOS, and visionOS), Android, React Native, Flutter, Roku, and a WebView tracker for hybrid apps. Other trackers cover Node.js, Python, Go, Java, .NET, PHP, Ruby, Scala, Rust, Lua, C++, and Unity.
Either works, and the choice usually depends on who owns tracking. Snowplow's Google Tag Manager templates deploy the JavaScript tracker with its full functionality, and Snowtype can generate code formatted for GTM custom JavaScript, so tags fire on the triggers and data layer you already have. Installing the tracker from npm, or using a native mobile SDK, keeps tracking in your app's code, where engineers get type-safe functions and ad blockers are less likely to interfere.
Keep tracking first-party, and send the events that matter most from your servers. Serve the Collector from a subdomain of your own site so its cookies are first-party, change its default POST path, and rename or bundle the JavaScript tracker so ad blockers are less likely to stop it. Safari can cap server-set cookies at seven days in some setups, so run a cookie lifetime extension service from the same IP space as your site to restore their lifetime.
Yes. The iOS and Android trackers store unsent events in an on-device SQLite database and send them once the Collector can be reached again. The web trackers queue events in browser local storage by default and retry requests t
