What walkerOS is
walkerOS is an open-source event data collection platform that captures, transforms, and routes behavioral events, with consent management built in. An event flow connects sources to a collector and destinations; it can run client-side, server-side, or in both places. Tracking features include HTML-attribute tagging, event mapping, and consent-aware queuing. Teams can set consent requirements for destinations and individual properties, with events held until consent is granted. Documented destinations include analytics tools such as GA4, Amplitude, Mixpanel, PostHog, and Segment; marketing services such as Google Ads, Meta, and TikTok; and warehouses such as BigQuery, Kafka, and SQLite. Users can build destinations for custom endpoints. The software is MIT-licensed and described as free with no event limits. It can be self-hosted with Docker or Node.js, bundled as a standalone artifact, or integrated into application code; managed hosting is also offered. Self-hosting keeps data on the customer's infrastructure, though that infrastructure's costs remain the customer's responsibility.
