Reach

Published to the Chrome Web Store on Manifest V3, Not Just Black earned 50,000+ impressions and peaked at 2,540 weekly active users — entirely through organic Web Store discovery, with no marketing spend.

The interesting part is the pipeline

The theme itself is a manifest and a palette. The engineering is in shipping it repeatably: a build and release pipeline built on Makefiles and shell scripting for CRX packaging, with OpenSSL signing for Web Store distribution.

That turned publishing from a manual, error-prone ritual into a single command — which matters when you’re managing the full product lifecycle solo, from development through Web Store review, publishing, and version updates.
