FOUNDER RESEARCH
Chrome extension market research notes.
I track Chrome Web Store rankings, listings, and growth data while building Extension Ranker. These are the real observations behind the product, published as they happen.
0 to 30k users in less 30 days. A website design extractor extension crazy
"Is it too late to build a Chrome extension?" I keep seeing this question. Then I found an extension called "Video Downloader." July 12: 127 users. No rating. No reviews. August 3: 8,000 users. That's 3 weeks. But here's what got me — on July 11, it was already ranking #1 for "download YouTube video as 4k" while it still had three-digit users. Today it holds top-5 on 23 keywords. It didn't earn its way up slowly. It just... walked in. That's not luck. There's a specific reason why that happens, and most developers never figure it out.
A Chrome extension changed its name: Ninja Block -> Ad Block Ninja Over the next month: Users: 10K → 100K users Reviews: 7 → 66 It can not prove rename drove growth. But it did indeed improve the searchability. What do you think?
Chrome extension "Cashback Master" went 40K → 100K users in 5 weeks. +150%. Buyhatke, same niche: 900K → 1M. Same window, the giant sprang a leak — Honey (PayPal): 13M → 12M. Down a million. Users leaking from the top are getting caught, cup by cup, by the small tools below. When the biggest player in a niche starts slipping: entry signal, or red flag?
Every AI product ships a side-quest. Gemini launched image generation. A tiny Chrome extension called "Gemini Watermark Remover" 7K → 30K users in 5 weeks. Half of that in the last 9 days. I'm not endorsing it. Just noting the pattern: The winners of an AI launch aren't only the labs. They're also the devs who ship the side-quest 48 hours later.
The 2026 World Cup has seen the rise of several "dark horses". One of them isn't on the pitch. A Chrome extension sat dead for 4 years — then came back to life with a rename. "World Cup Qatar 2022". 932 users. Zero momentum. One week before kickoff, the dev renamed it "World Cup 2026". One month later: 5x users. 5.0 rating. Same product. Same code. The only change: a title pointed at what people actually search. Dark horses on the pitch aren't just luck. Neither was this one. Good Job @cesarwbr !
Fastest-growing indie extension in Extension Ranker database over the past 5 weeks: Tally, a Claude token counter. Users 30K → 70K Reviews 369 → 1,100 Rating steady at 4.5 A pure utility tripling its review count in 5 weeks means people actually use it daily. Curious @DivyKairoth — is this mostly organic pull from the Claude ecosystem, or did you push somewhere?
