What happened to Kozmos with the Chrome Extension Team?

Kozmos built a bookmarking extension and was flagged by the Chrome Extension Team for a policy violation with no specific explanation. After months of unanswered appeals, the founder shut down the company in May 2020. The HN post drew 1178 points.

How long does Chrome extension review take?

Chrome Web Store review takes 1-2 weeks on average. Appeals can take equally long with no guaranteed human reviewer. Developers receive automated emails naming the violated policy but not the specific observed behavior triggering the violation.

Can a Chrome extension be removed with no recourse?

Yes. Google can remove a Chrome extension at any time. Developers have the appeal process but no SLA, no guaranteed human review, and no independent arbitration. Revenue from an extension business can disappear overnight.

Chrome Extension Team's opaque arbitrary review process has shut down indie extension businesses with no recourse

In May 2020, Kozmos shut down after the Chrome Extension Team flagged and removed their extension with no clear explanation and did not respond to appeals for months. The HN post 'Unable to deal with Chrome Extension Team, Kozmos is shutting down' drew 1178 points and 82 comments. A 2023 HN thread 'Temptations of an open-source Chrome extension developer' (1123 pts, 50 comments) describes how Hover Zoom+ developer received 130+ acquisition solicitations and faced constant compliance pressure with no developer support from Google. Extension developers describe review emails that name the violated policy but not the specific observed violation, with appeals taking 1-2 weeks and no guarantee of a human reviewer. This creates an existential risk for any extension business: Google can remove the distribution channel at any time without explanation.

Product Idea from this Signal

A web app that audits Chrome extensions for policy compliance before submission and manages CWS appeal workflows

2.4k ▲

Indie extension developers routinely have their businesses shut down by opaque, arbitrary Chrome Web Store review decisions they never see coming. There is no tool that scans an extension against Google's evolving policy set before submission, predicts likely rejection triggers, and then provides a structured appeal workflow with evidence templates and status tracking when a takedown does hit. This app closes that gap: pre-submission compliance audit, real-time review-status monitoring, and a managed appeal layer that keeps developer businesses alive.
