Spec score 7.7 #13 of 24 in Event Tracking Software

What it 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 through a collector to destinations and can run client-side, server-side, or in both places. Tracking features include HTML-attribute tagging, event mapping, and consent-aware event queuing. Teams can require consent for particular destinations or properties, with events held until consent is granted. Documented destinations span analytics services 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 MIT-licensed software is 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 described. Self-hosters pay their own infrastructure costs. Integrated mode offers TypeScript control, while bundled mode uses JSON configuration and the CLI.
