Summary

Ethyca Fides is an open-source privacy engineering toolkit for defining data categories, purposes, and use cases across fragmented systems. It turns regulatory obligations into machine-readable definitions that can be enforced within infrastructure. APIs and tooling connect it to development workflows, where teams can classify and authorize data used in AI training and inference. The sample deployment includes a webserver and Admin UI for privacy requests, a Privacy Center, and an example e-commerce project. Its Cookie House sample uses MongoDB and Postgres; listed integrations include Salesforce, Shopify, Segment by Twilio, Google Analytics, Slack Enterprise, and Zendesk. Fides supports data inventory, automated discovery, DSAR and retention management, with hybrid deployment. Local setup requires Python 3.8–3.10 and Docker 20.10.11 or higher. The free toolkit is available for API, Linux, macOS, self-hosted, web, and Windows environments. The onboarding guide directs users seeking setup help to the Fides Slack community.
