Discover projects in the projects nav filtered by the tags pillar for 'ad-tech'—a curated list of open-source and commercial initiatives building programmatic advertising systems, real-time bidding (RTB) engines, demand-side platforms (DSPs), supply-side platforms (SSPs), header bidding wrappers, and privacy-first identity resolution and cookieless attribution solutions. This collection emphasizes technical projects for targeting and audience segmentation, measurement and analytics, fraud detection, data clean rooms, SDK integrations, and ML-driven bidding optimizations, offering architecture patterns, data pipeline examples, and monetization strategies. Use the filtering UI to narrow results by tech stack, deployment model, license, or maturity; compare repository code and documentation, evaluate integration effort, and prioritize projects for testing, contribution, or production deployment. Actionable next steps: view project details and implementation guides, clone repositories, run reference deployments, and contact maintainers to accelerate compliant, scalable ad-tech development.
