OpenPIMS Six months of Prototype Fund, for the second time. The project: OpenPIMS – abolishing cookie banners through centralized consent management.
This project was funded as a private individual through the Prototype Fund.
The Goal
With TDDDG §26, there is finally a legal framework for PIMS in Germany. OpenPIMS was meant to provide this infrastructure: Set once centrally, apply everywhere.
What Was Built
- 3-tier consent system – by category, provider, or individual cookie
- Browser extensions – Chrome, Firefox, Safari, Edge (unified codebase)
- Privacy proxy – Python mitmproxy addon + Cloudflare Worker
- Magic link login – No passwords, deterministic tokens
The Problem
Technically it works. But: Chicken-egg problem. Without websites, there is no benefit for users. Without users, there is no incentive for websites.
Status
OpenPIMS is on hold. The code is on GitHub. Focus is now on PrivacyProxy and TrialCode.
Sometimes pausing is the right decision.
