5 Best Chrome Extension Competitor Analysis Tools (2026 Ranked)

Building a Chrome extension without analyzing your competitors is like driving blindfolded. You might get there, but you'll probably crash first.

In 2026, the market is too crowded for guessing games. You need data. You need to know:

• What your competitors are changing.
• Why their users are leaving 1-star reviews.
• How fast they are growing.

There are dozens of "analysis tools" out there. Most are broken scrapers or abandoned projects.

We tested the market and ranked the top 5 Chrome extension analysis tools that actually work in 2026.

1. Extension Radar (Best Value & AI Insights)

The "Smart" Choice for Indie Developers.

Most tools just give you raw data. "Competitor X has 10,000 users." Okay, but why?

Extension Radar is built differently. It uses AI to read thousands of reviews and tell you why an extension is growing or failing.

• AI-Powered Analysis: Instantly spots bugs ("Users hate the new update") and feature gaps ("Everyone is asking for dark mode").
• Chat with Data: Ask questions like "What is the most common complaint?" and get an instant answer.
• Affordable: Designed for indie developers, not enterprise sales teams.

Pros:

• ✅ Best-in-class AI sentiment analysis.
• ✅ Specific actionable insights (bugs, feature requests).
• ✅ Very affordable ($8/mo vs $15+ competitors).
• ✅ Generous free tier.

Cons:

• ❌ Newer to the market than Chrome-Stats.

Pricing: Free tier available. Pro plan at $8/month (One-time payment options available).

2. Chrome-Stats (The "Legacy" Heavyweight)

The "Big Data" Choice.

If you've been in the extension game for a while, you know Chrome-Stats. It is the massive database of the Chrome Web Store.

If you need raw historical csv data going back 5 years, this is your tool. It tracks everything from rank changes to description updates.

Pros:

• ✅ Huge historical database.
• ✅ API access (for enterprise plans).
• ✅ Tracks search keyword rankings.

Cons:

• ❌ Expensive: Plans start effectively around $15-20/mo and scale up fast.
• ❌ Complex UI: It feels like a spreadsheet on steroids. Overwhelming for beginners.
• ❌ No AI Insights: You have to read the reviews yourself.

Pricing: Free limited tier. Paid plans start at ~$15/mo.

3. Sensor Tower (The Enterprise Choice)

The "Fortune 500" Choice.

Sensor Tower is the industry standard for mobile app intelligence. They also cover browser extensions, but it's an afterthought to their mobile data.

This is a tool for VCs and large corporations who need to estimate revenue for acquisitions.

Pros:

• ✅ incredibly accurate revenue estimates.
• ✅ Enterprise-grade data security.

Cons:

• ❌ Extremely Expensive: Pricing is usually "Contact Sales" (expect $$$$/month).
• ❌ Overkill for 99% of extension developers.

Pricing: Custom Enterprise Pricing.

4. Google Trends (The Market Validator)

The "Big Picture" Choice.

Sometimes you don't need to analyze a specific competitor; you need to analyze the topic.

Google Trends is free and essential for validating demand. Before you build an "AI Email Writer," check if the search volume is trending up or down.

Pros:

• ✅ 100% Free.
• ✅ Shows macro market interest.

Cons:

• ❌ Doesn't show specific extension data.
• ❌ Broad match keywords only.

Pricing: Free.

5. The "Manual Method" (Spreadsheets)

The "I Have More Time Than Money" Choice.

We wrote a whole guide on how to do this, but here is the summary:

1. Open your competitor's store page.
2. Filter reviews by "Recent".
3. Copy/Paste them into Excel.
4. Tag them manually (Bug, Feature Request, Praise).

Pros:

• ✅ Free.
• ✅ You really "feel" the user pain by reading every review.

Cons:

• ❌ excruciatingly slow.
• ❌ Hard to track changes over time.
