RocketMetrix — Поиск копий карточек на Ozon ·

Ozon pushed the work of reporting copycat listings onto sellers, and an analytics tool built a plugin to handle it: RocketMetrix's copy-finder plugin, 500 users in three months

What it is A Chrome extension for Ozon sellers. It scans your store for cards that have been copied or had their images stolen (down to each size), and exports an Excel file pairing “my SKU — copy SKU” to file complaints with. You must log into RocketMetrix, a paid analytics tool, to use it.

Why it took off In May 2026 Ozon changed copy complaints to one-by-one submissions that require matching SKUs, which big stores couldn't handle by hand. It grew through paying users of the main product, Instagram DM funnels offering a free complaint service for a keyword, and the fact that most similar tools aren't in the store. That made it the most-used tool in the store.

CWhat you can take from it Don't build another standalone copy-finder extension for Ozon. Borrow the playbook instead: when a platform pushes review work onto sellers, automate that busywork in a plugin, bolt it onto your existing seller tool with a forced login, list it in the store properly, and get leads with short videos that hit the pain point, plus DMs with a keyword.

C grade: Ozon has seen seven or eight copycats in five months, and the biggest one has only 500 users. RocketMetrix leads because of its own paying user base, which followers can't match. When the platform builds the feature in, the whole category dies. The playbook is worth learning, but copying it isn't worth the money. Almost nobody knows about it yet

RocketMetrix is a Russian e-commerce analytics product. Its Chrome extension helps Ozon sellers scan their own product cards for clones and copied images, mostly from Chinese sellers, and export the results to an Excel file ready to attach to complaints. It launched in Jul 2026 and had 25 users by Nov 6 499. That's small, but it sits in a niche that spawned seven or eight similar products in five months. Below: how the niche came about, how RocketMetrix got to the top of the store, and whether it's worth getting into.

"Is Ozon taking the side of Chinese sellers?"

On May 25, 2026, sertcity.ru, a Russian certification consultancy site, ran a piece headlined with a seller's gripe: "Ozon sides with the Chinese? Russian sellers complain about new rules for deleting duplicate cards." The article says Ozon changed its complaint process. Before, removing one copycat listing was no big deal. Now every duplicate needs its own complaint, citing the original card's SKU and the copy's SKU, plus proof that you're the original author. On hot categories, a good-selling card often gets copied dozens or even hundreds of times. The article quotes the line: "the platform is effectively shifting the main burden of fighting copies onto sellers." It jokes that "sellers will soon have to hire someone just for this."

A month later, in Jun 26, a developer who sells on Ozon posted on vc.ru: "I built KickChina, an extension that finds your card clones on Ozon and hides them." The post was short. It got 676 views and 7 comments.

Another month later, in Jul 25, RocketMetrix's extension went live on the Chrome Web Store. In Oct 25, RocketMetrix posted a short video on Instagram with this caption:

"Chinese sellers are copying your Ozon cards and taking your profit. Same photos, lower price, and your orders go to them… Send the word СЕРВИС in a DM to get 10 free complaints."

By Nov 6 the post had only 2 likes. That's the extension's real size: a very narrow need that hurts a lot.

What it actually is

According to the store page, you enter your brand name or store link. The extension goes through all your products and expands every size (on Ozon each size is a separate card, and a clone may be attached to just one size). Then it reads the "other sellers' offers" section under each card, where everyone who piggybacked on your listing shows up. Finally it builds a table with seller, price, country, your SKU, the clone's SKU, and a link, and exports it to Excel, which the store page says is "convenient for filing complaints with Ozon support." Those two SKU columns are exactly what Ozon's new complaint process asks for.

It also has one extra feature: it checks a competitor's real stock on Wildberries by adding items to the cart.

The last line matters most: the extension itself doesn't make money. It's the entry point to RocketMetrix's main product.

The company behind it

The RocketMetrix site (rocketmetrix.ru) leads with an "AI analyst": it connects to your Ozon and Wildberries store back-office and handles profit reports, ad analysis, and AI-written product copy. Pricing has four tiers by monthly store order value, at 3,490 / 5,490 / 6,990 / 9,990 rubles per month, with a 7-day free trial. The site claims its users' stores together place 825M rubles of orders a month (the company's own figure, unverified).

The founder, Алексей Кижаев, is himself an Ozon seller. A post on the seller forum sellermap.online from 2026 Feb 20 says he has "solid sales on Ozon," and that he built the tool because he couldn't find a data tool he liked. It was still in testing then and only supported Ozon. In Apr 15, a seller community on VK called "Синий рассвет" ran a livestream and demoed RocketMetrix live, using a guest's store backend.

So this extension isn't a small tool one person built from scratch. It's an add-on from an analytics product that already had paying customers, added after the platform changed its rules.

Where users come from

Existing customers and trial users of the main product. You can't use it without logging into RocketMetrix, so most of the 499 installs are probably sellers already paying or on trial (an inference; the exact split isn't visible from outside).

A "comment a keyword" funnel on Instagram. RocketMetrix's posts and the founder's personal account both run the same kind of short video: "Chinese sellers are copying your cards," ending with "DM СЕРВИС for 10 free complaints" or "comment сервис for 7 days free." They use a concrete pain point to pull people into DMs, then send them to a trial of the main product. The brand account has only single-digit followers, so reach is small.

Chrome Web Store search. Searching the store for "клоны ozon" or "копии ozon" in Russian turns up this one and a few similar tools with a few dozen to a hundred-plus users. KickChina, the earliest, and OzonShield, which came later, aren't on the store. Users download a zip and install it by hand, which (inference) gives up the store's search traffic.

What I didn't find: no press coverage, not one mention on X in 90 days, and no sign of paid acquisition. The growth curve is a straight line.

Ozon's own "block card copying" settingAll sellersHas existed since 2021; it only stops one-click copying, not copycats or image theft

On features, RocketMetrix isn't the deepest: KickChina and KlonOff both do image matching and automatic complaints, while its store page only mentions Excel export. (Its October Instagram post says it can already match images and file complaints automatically, but the store page doesn't say so yet.) It tops the store because of two things others don't have: a set of users already paying for its analytics software, and a properly listed, searchable store page.

The crowd of similar tools isn't copying it. They appeared almost at the same time because one platform rule hurt the same group of sellers at the same moment.

Where the money comes from

The extension doesn't charge. The money is in the main product's subscription, whose cheapest tier is 3,490 rubles a month, more than double KickChina's 1,490 rubles for its standalone extension. For RocketMetrix, a seller who installs the extension and later upgrades to a subscription is worth far more than someone who buys only the extension. I couldn't find how the complaint service is priced separately.

If it were you

C: you can learn a playbook from it, but copying it isn't worth it. On Ozon, this niche has produced seven or eight entrants in five months, and the biggest has only 500 users. RocketMetrix leads on its own paying user base, which newcomers can't reach. If Ozon builds bulk complaints in itself one day, the whole category of extensions becomes useless.

Who it suits: teams that already have a paid tool for sellers on one marketplace (analytics, listing, or ads) and a base of paying users, and want a sharp, free little feature to bring in new users. Or sellers at scale on one platform who get worn down by clones and image theft every day and know the process inside out.

Who it doesn't suit: people who want to build another standalone clone-finder for Ozon to earn subscriptions from. KickChina's 1,490 rubles and OzonShield's 649 rubles already undercut each other, and seven or eight more tools are chasing the same people. Also anyone who doesn't read Russian or know the Russian seller community. And anyone aiming for a big user count: this is a few-hundred-to-few-thousand-user B2B business.

How to do it: the thing to borrow is the playbook, not this extension. Wait until a platform pushes review work onto sellers (one complaint at a time, one ID at a time, one proof upload at a time), then automate that repetitive work with a browser extension, ideally attached to your own main product with a forced login. If you want to build clone-finding itself, you can switch platforms: Wildberries, Kazakhstan's Kaspi, and Poland's Allegro all have copycat problems. Which one has the most painful recent rule change, and which one nobody has covered, I haven't verified. You'd need to check the local seller groups yourself. Whatever you build, fill the gaps RocketMetrix leaves: image matching, automatic complaint filing, and tracking which complaints get rejected.

How to get users: list it in the store, don't hand out zips. Any copycat that isn't on the store is effectively giving its search traffic away. Write the listing title in the local language and include the words sellers actually search, like "clone," "copy," and "complaint." Then follow RocketMetrix's approach: make short videos like "X is copying your cards" that hit the pain point, end with a keyword to comment or DM for a few free complaints, and send people to a trial of the main product. Seller forums and community livestreams work far better than X or Reddit here. This niche has zero discussion on X.

When to move: demand created by a platform rule change has a window that closes once the platform builds the feature itself. The Ozon wave is already half a year old and crowded. The next good moment is the first month or two after a platform announces that some review, complaint, or compliance work is now submitted by sellers one item at a time.

Signs you've misread it: ① By early 2027, RocketMetrix or another similar extension passes 5,000 users on the Chrome Web Store. That would mean the need is bigger than estimated here and there's room for an independent product on Ozon. ② Similar extensions show up on Wildberries or Kaspi and pass 1,000 users within a few months. That would mean "do it again on another platform" works. ③ The reverse: if Ozon itself ships bulk clone-finding and bulk complaints, this whole category of extensions loses users. Don't invest then.

RocketMetrix — Поиск копий карточек on Ozon: why it's ranking

Chrome extension · id ignennlddkmeglnlocldepndaipgnmej · research date 2026-11-06

One line

This is a Chrome extension bundled with RocketMetrix (rocketmetrix.ru), a Russian e-commerce analytics SaaS. It scans every product in a seller's Ozon store (including the separate cards for each size), flags the cards that are resold or use stolen images (mostly from Chinese sellers), and exports a "my SKU — copy SKU — seller — price — country" Excel sheet for filing complaints with Ozon. The extension isn't sold on its own. It requires a RocketMetrix subscription or "separate widget access". It serves as the SaaS's lead-generation entry point.

It took off because of three things:

  1. A platform rule change created the pain point: around 2026 May, Ozon changed its copy-complaint process. Each copy now has to be reported separately, with the original card's and the copy's SKU pairs filled in.
  2. SaaS and founder content drive traffic: founder Алексей Кижаев is himself an Ozon seller. On Instagram he runs a "comment a keyword, get 10 free complaints / 7 days of trial" lead funnel.
  3. It's nearly the only serious one on the Chrome Web Store: KickChina and OzonShield are distributed as zip files that users load manually. KlonOff, Declone and Unplagiator have only tens to about a hundred users each on the store.

Overall scale is still small: about 500 users and 1 ratings. This is a newly emerging niche B2B category.

1. Basic data

  • Chrome Web Store (2026-11-06 detail page scraped directly): 499 users, 5.0 stars from 1 ratings, v3.61.1,2026-10-12 latest version, 631KiB, Russian only. Developer email [email protected], support page t.me/kizhay, no trader status listed. The privacy disclosure only mentions collecting authentication information.
  • First published 2026-07-25 (data card).
  • Our database: chromestore.item_snap 2026-11-01 reads 480 users / 1 ratings.
  • Extops curve on the recall card: 2026-09-01 is 155,11-06 and 491; from 10-08, it grew 168 over 30 days, roughly +5 per day, very steady. The first rating came on 10-16. Between 9 and October it shipped 6 versions (3.43 → 3.61). No spikes seen, so it doesn't look like paid acquisition.
  • Original description: "Для работы нужен аккаунт RocketMetrix с активной подпиской или отдельным доступом к виджету".
  • The store title and summary also advertise a second feature: checking real stock on Wildberries by adding items to the cart.

2. Parent company / founder

  • RocketMetrix website (rocketmetrix.ru, 2026-11-02 version): markets itself as an "AI analyst". It connects to Ozon and WB store back ends via API to do P&L, ad analysis, hypothesis libraries, and AI copywriting. It claims users' total monthly order value is 825M ₽.
  • Pricing has four tiers by monthly store order volume: 3,490 / 5,490 / 6,990 / 9,990 ₽/month. An extra store adds +1,990, an extra user adds +690. 7-day free trial.
  • Founder Алексей Кижаев: a sellermap.online 2026-02-20 post describes him as "a seller with solid revenue on Ozon". Unable to find a satisfactory data tool, he built RocketMetrix himself. It was still in beta and supported only Ozon at the time.
  • 2026-04-15: the VK community "СИНИЙ РАССВЕТ" hosted a livestream that live-demoed RocketMetrix on a guest's store back end.
  • Around 2026-11, the founder's Instagram (@kizhay93) and Threads packaged "find copies + automated complaints" as a standalone service: first 10 free complaints, then a funnel to a 7-day trial of the main product.

Takeaway: the category suddenly emerged in 2026 6–October, and at least 7 players are building it at once. RocketMetrix is not the first (KickChina came earlier), and its features aren't stronger than rivals'. It mainly exports Excel, and its complaint automation is less complete than KickChina's and KlonOff's. It has the most users on the Chrome store for two reasons: it's officially listed there, so it's searchable, and it sits on top of a SaaS user base that already pays.

4. Growth tactics (evidence)

  • Existing SaaS users / trial users (confirmed): the extension requires logging in with a RocketMetrix account, and it only works with a subscription or "widget access" (store description). So most installs likely come from SaaS and trial users. The 825M ₽/month GMV claimed on the website suggests a batch of paying stores (unverified).
  • Founder runs reels on Instagram / Threads and lead-gen via comment keywords (confirmed):
    • "Напиши в директ слово СЕРВИС, 10 бесплатных жалоб" (instagram.com/p/De7jRKXiFe8)
    • "Оставь в комментариях слово «сервис» — 7 дней бесплатно" (reel DbQ6PdRoEm1)
    • A batch of short videos on the "Chinese sellers copying your cards" pain point (DbL0u78oOZi, DeLyiiQNGBs, DeYxfl0oLUY, etc.)
    • The brand account @rocketmetrix has only 5 followers; most content is posted on the founder's personal account. Follower count not captured (Instagram requires login).
  • Seller communities and livestreams (confirmed): a sellermap.online 2026-02 recommendation post; a livestream on VK "Синий рассвет" 2026-04-15.
  • Chrome Web Store organic search (inferred): search the store for "клоны ozon" or "копии ozon" and it shows up alongside Declone, KlonOff and Unplagiator; next to its "related" listings are MP analytics extensions like Moneyplace and ТурбоМинимум. KickChina and OzonShield aren't in the store, so that traffic goes to the ones that are.
  • Nothing seen: no discussion on X (x-radar 90 days 0 posts); no media coverage; no sign of paid acquisition, the curve is linear.

5. Why now

  • Chinese sellers copying Ozon cards in bulk, cloning listings and stealing photos: this problem was already being reported 2025 years ago (selsup 2025-05, BFM), and 2026-08 VK seller groups are still complaining.
  • Around 2026-05, Ozon changed its complaint process (sertcity.ru 2026-05-25): every copy now has to be reported separately, with both the original card SKU and the copy SKU. Big stores often have dozens or hundreds of copies, so manual handling suddenly got expensive, and "find them in bulk and pair up the SKUs" became a must-have. RocketMetrix's Excel export contains exactly those two SKU columns, and its description says outright: "convenient for complaints to Ozon support".
  • Ozon's built-in "copy protection" doesn't stop cloning sellers (oborot.ru, klonoff.ru), and the platform hasn't closed that gap.
  • 2026-10-01, the platform economy law (289-FZ) took effect. Platforms started handling card complaints and compliance more seriously, and sellers came to expect that "a complaint = action" (this is inference, not direct evidence).

6. Differentiation

  • Depth isn't its edge: KickChina and KlonOff do image comparison, automatic complaint submission and rejection prediction. It mainly scans the "Other offers from sellers" block and exports to Excel. It has one detail the others don't mention: it expands every size into its own card to scan (a copy may be attached to only one size). It also comes with a feature to check WB stock through the cart.
  • The real difference is distribution and business model:
    • It isn't sold separately. It's a lead-gen and retention tool for an analytics SaaS starting at ₽3,490.
    • It's properly listed on the Chrome Web Store.
    • The founder is a seller himself, and runs an Instagram funnel built on emotional content like "Chinese people copy your cards".
    • These are why it leads on store users. But with 499 as the absolute number, it's far too early to say it has "broken out".

7. Visibility and copycats

  • Visibility: few people know about it yet. The extension has no media coverage, there are 0 posts on X, and the brand's IG has 5 followers. The category has spread in small circles, though: there's a vc.ru post by the KickChina author and a KickChina tutorial article (3170940); KlonOff is doing SEO content.
  • Copycats: 6–7 others were building for the same need at almost the same time (see the competitor table). That suggests a category pushed out by a platform rule change, not someone copying RocketMetrix.

8. Takeaways

  • Watch platform rule changes: when a platform pushes review work onto sellers (like one-by-one complaints or SKU pairing), a browser extension is the fastest way to automate the repetitive labor, and it ships quickly.
  • Use a small tool to feed the main SaaS: build a free or low-barrier tool for a sharp pain point, require login with the main product account, and convert extension installers into trial and subscription users. That yields far higher ARPU than selling a ₽1,490 extension alone.
  • Listing in the store matters: competitors distributing as zip files have effectively handed over the store search traffic.
  • The same model can move to other markets with cloning and photo-theft problems: WB (digital arbitration), Kaspi, Allegro, Amazon and others.

9. Uncertain

  • How many installs are paying SaaS users versus users with a "standalone component" permission (possibly a separate complaint-service plan) is unknown, and I couldn't find how the complaint service is priced.
  • Couldn't capture the founder's IG follower count or reel view numbers.
  • Haven't verified the actual install base of KickChina and OzonShield's zip distribution; their total users may exceed RocketMetrix's.
  • The site's ₽825M/month revenue figure is self-reported.
