What to Know Before Buying Chrome Goldmine

Chrome Goldmine is a one-time purchase: $29 standard, or $23.20 for the first 100 buyers (20% off), with a 30-day no-questions money-back guarantee. You get an instant Notion workspace plus CSV, and lifetime quarterly updates. There is no subscription. If you're an indie maker looking for expired Chrome extensions to rebuild, the price is low enough that the main question isn't cost — it's whether the data matches how you plan to pick a project.

Pricing and What Triggers the Discount

The discount is capped at 100 buyers, after which the price returns to $29. If you're reading this after that window closes, assume $29. The $6 difference is small relative to the time you'd spend evaluating extensions, so don't let the deadline rush a decision you'd otherwise make carefully.

What You Actually Receive

Delivery is two formats plus ongoing updates:

• Instant Notion workspace — the browsable database of listings and reports.
• CSV — the same data in a form you can filter, sort, or import elsewhere.
• Lifetime quarterly updates — new expired extensions and refreshed data four times a year.

The CSV matters if you want to rank opportunities by your own criteria (for example, historical users divided by rebuild difficulty) rather than reading listings one at a time in Notion.

What's in Each Extension Report

Every listing covers an extension that people already installed before it died. According to the site, each report includes:

• Historical user count
• Category
• Rebuild difficulty
• Why it died
• Who competes now
• A step-by-step rebuild plan
• Estimated monthly revenue range

The sample rows show the shape of this. For example, Session Stack is listed with 48,200 historical users, Productivity category, Low difficulty, died from MV3, and an estimated $500–$1,600/month. Tab Suspender Reloaded shows 91,400 users, Medium difficulty, MV3, $600–$1,800/month. The full report expands to a 12-point format.

Preview Before You Buy

You can browse a sample without signing up: 20 live rows out of 9,656, plus one complete report. The remaining 9,636 rows unlock at checkout. Use the sample to check two things — whether the report depth matches what you need to scope a rebuild, and whether the categories (Productivity, Accessibility, Customization, Shopping, Writing, New Tab) overlap with what you can actually build.

Why "Expired" Counts as Proven Demand

The logic is that these extensions had real installs before they stopped working, so demand existed rather than being hypothetical. Many died for a specific, often fixable reason — the sample repeatedly cites MV3 (Manifest V3 migration) and abandonment. That's the pitch: you inherit a validated audience and a known failure cause instead of guessing at a market.

Treat the estimated monthly revenue as a range, not a promise. It's a projection attached to each listing, and your actual result depends on execution, competition, and how the extension is monetized.

A Reasonable Way to Decide

1. Open the free sample and read the full 12-point report for one extension.
2. Ask whether you could realistically ship that rebuild — check the difficulty rating against your skills.
3. If the report gives you enough to scope the work, the $23.20–$29 price is a small bet; the 30-day refund covers the case where it isn't.
4. If the sample feels thin or the categories don't fit what you build, skip it — the discount isn't a reason to buy data you won't use.

The purchase decision really comes down to whether one usable rebuild idea is worth roughly the price of a couple of coffees. The refund window means you can verify that after paying, not before.
