Eat My Cookies vs Consent-O-Matic

Consent-O-Matic is an excellent open-source project from Aarhus University. Philosophically, we're closely aligned — no backend, no tracking, privacy-first. The differences are in scope, maintenance pace, and features built around real-world edge cases.

Where Consent-O-Matic excels

Consent-O-Matic was one of the first rigorous, API-based consent automation tools. It pioneered the approach of using CMP APIs rather than brute-force selector clicking. The Aarhus University team has done genuinely important work in this space, and the academic rigor shows in the tool's design.

Where Eat My Cookies goes further

Eat My Cookies adds per-site exception management, transparent failure warnings (so you always know when automation couldn't succeed), a five-layer fallback architecture for resilience, CCPA coverage for US publishers, and an activity log with collectible badges. It's also more actively maintained for the kinds of real-world edge cases that break other tools — geo-specific flows, A/B tested banners, paywall-style consent gates.
