Chrome Goldmine

What it does

Chrome Goldmine is a curated database of over 9,650 expired Chrome extensions. Each listing includes research data such as user count, ratings, reason for expiration, competitor analysis, and key selling points. The platform also provides guides on how to rebuild these extensions, turning them into potential micro-SaaS products.

Who it is for

The product is aimed at indie makers, solopreneurs, and small teams looking for validated, low-competition product ideas. It is particularly useful for those who want to build browser extensions as a side project or full-time business, without spending weeks on market research.

Why it matters

Finding a profitable product idea is one of the hardest parts of starting a micro-SaaS. Chrome Goldmine reduces that friction by surfacing extensions that already had users and traction, but were abandoned. This gives builders a head start: they can see what worked, what didn't, and what competitors exist. The included guides also help non-technical founders understand the rebuild process.

Launch signal

Chrome Goldmine launched on Gumroad as a digital product. The founder, Raf Vantongerloo, appears to be an indie maker who built the database as a side project. The website is a static Vite build hosted on Lovable with Cloudflare DNS. No public funding or team size is disclosed.

Brand and naming

The name "Chrome Goldmine" is descriptive and memorable, combining the platform (Chrome extensions) with the value proposition (a goldmine of opportunities). It positions the product as a treasure trove for builders. The tagline "9,656 Expired Chrome Extensions. All Research Done. Your Customers Waiting." reinforces the core benefit: ready-to-use market research.
