A browser extension that auto-rejects cookie consent banners with a verified open-source trust model
Every major cookie auto-reject extension has either been acquired by a data broker (IDCAC sold to Avast, Avast fined $16.5M by FTC for selling browsing data) or remains an academic project too complex to maintain at scale. Users who relied on these tools have nowhere to turn that is both effective and trustworthy. A privacy-first, transparently audited, Manifest V3-native extension that auto-rejects non-essential cookies can capture this displaced audience and monetize through a paid tier for advanced features.

Trust is gone and users are actively seeking replacements.; Run by researchers, not a product team. No paid tier, no dedicated maintenance. CMPs are actively building countermeasures (OneTrust CAPTCHA patent). No MV3 native build. No user-facing trust signals beyond the GitHub repo..

Competitive LandscapeFREE
| Product | Does | Missing |
|---|---|---|
| I Don't Care About Cookies | Largest cookie consent auto-dismiss extension in the space with 2M+ users. Auto-accepts or hides cookie banners on thousands of sites using a curated filter list. | Acquired by Avast in 2022. Avast was fined $16.5M by FTC in 2024 for selling user browsing data. The product is fundamentally compromised as a privacy tool. Trust is gone and users are actively seeking replacements. |
| Consent-O-Matic | Academic open-source extension from Aarhus University. Automatically fills cookie consent forms with reject-all, with a complex rule database mapping known CMP vendors. | Run by researchers, not a product team. No paid tier, no dedicated maintenance. CMPs are actively building countermeasures (OneTrust CAPTCHA patent). No MV3 native build. No user-facing trust signals beyond the GitHub repo. |
| Ghostery | Full-featured tracker blocker and ad blocker that also handles cookie consent banners as part of a broader privacy suite. Has a paid tier (Ghostery Plus/Midnight) and mobile apps. | Consent management is a secondary feature, not the core product. Ghostery itself has a complicated past (was acquired by a German ad-tech firm Cliqz, then bought back by employees). Bundle approach means the cookie-rejection quality is not the focus. Overkill for users who just want clean cookie handling. |
| Auto Cookie Decline (bymitch 2025) | New open-source Chrome extension launched April 2025 targeting the IDCAC trust gap. Gained 328 HN engagement on launch. | Still small, unverified coverage, no paid tier, no organizational backing. Single developer project with no disclosed sustainability model. |
