5,000 users for nothing, $99 once for 2,000: five Chrome extensions that add a second interface

Every extension on this week's list adds a second interface to a page somebody else built.

A comment box that takes text, with a layer that draws GIFs inside it. A streaming page, with a side panel that lists every video stream that page loaded. A Zillow listing, with a scoring panel in the corner. A page with a bug on it, and a recorder that saves the browser console beside the screenshot. A chat history, and a panel that deletes it in batches.

Five products, five prices: nothing, $1.99 a month, $6.99 a month, $7 a seat, and $99 once. The biggest of the five charges nothing. The most expensive sells to somebody buying a house.

The week's largest numbers were somewhere else. A Monero wallet added 299,835 users in one day, from a base of 165. 1 Jumpstart Search and its new-tab companion added 19,997 and 9,995 users in one week, and the publisher says both are free. 23

None of them is profiled here. The wallet sits above the 200,000-user ceiling this list works under, and the Jumpstart pair sets Yahoo as the browser's default search engine, the arrangement this list covered on 6 October. All three appear in the closing notes among the listings checked and set aside.

Adjacent niches: car marketplaces, rental portals, secondhand sites, course platforms, webinar archives. Each holds items a buyer compares over weeks, inside a page nobody built for comparing them.

Install counts and movement come from Chrome-Stats, read on 20 October 2026 beside each extension's live Chrome Web Store listing.

Six Chrome-Stats lists rank extensions by the size of a change, three by percentage and three by absolute count. 4 The absolute lists held only apps in the millions this week, so the percentage lists did the discovery. Every figure below is quoted with its window and the base it grew from.

Chrome-Stats prints a one-month percentage for entries that reach its top 25, which among this issue's five covers Property Shortlist alone. 4 For the rest there is no public 30-day figure, so movement is given as a one-day, one-week or one-month change, whichever the source states.

All five appeared on a Chrome-Stats list read this week, and the window in which each moved can be longer than the week. The band is 5,000 to 200,000 users. YouTube GIF Comments clears it at exactly 5,000. Four of the five sit under it. 7Frames AI is inside the 60-day window the selection rule allows, and Bulk Delete's only store version dates from 12 October. Stream Katcher and Property Shortlist are older and smaller, kept for a published price and a job narrow enough to verify. Each of the four carries a borderline label where it appears.

Each revenue figure is a scenario: current users × an assumed paid share of 1–3% × the published price. A one-time purchase produces single sales, labelled as such. Where nothing is sold, the range is unavailable.

Installs at the start of each extension's own measurement window against installs on 20 October 2026, on a linear axis, from Chrome-Stats 2 and 1 read that day. The window is named on each label because the five do not share one: Bulk Delete is a single day, Property Shortlist a month. Every grey bar sits at or below twelve: five listings that sat near zero until the week they moved.

The extension reports 5,000 users, a 2.7 rating from 23 ratings, and version 2.0.3, updated 19 October 2026. 9 Chrome-Stats dates its creation to 11 June 2026, shows a single storage permission, host access to api.imgur.com and tenor.com, and a content script on youtube.com. 10 MrSkally publishes it as an individual, files as a non-trader, and lists a Gmail address for support. 9

+4,997 users in one week, from a base of three, is the largest gain of these five. 2 The jump landed in the same week as a version change: on 18 October the extension went from 1.2.0 to 2.0.3, added tenor.com and dropped its youtube.com host permission. 10

Browser-only behavior. Paste a GIF link into a YouTube comment and the extension writes a reference there; anyone with the extension installed sees the animation inside the comment thread. 9 Readers without it see text and an image identifier.

Monetization and MRR scenario. Unavailable. There is no purchase label, no price and no account, and the developer files as a non-trader. The 2.7 rating is what 23 people made of a tool that only works when the other person has installed it.

Why Chrome, and where the opening is. The drawing happens in the reader's browser, on a page that renders comments as text. The nearest listing doing the same job is Dwarfer GIF, at 3,000 users and +2,994 in the same week, which describes itself as experimental. 2 Two listings under 5,000 users, one of them at 2.7 stars, leaves an opening for a third. A two-week version picks a platform whose comments reject media and fixes the receiving end first: a hosted link that animates for people who never install anything. At a one-time $4, it has a buyer the free version never found.

The extension reports 4,000 users, a 5.0 rating from 3 ratings, version 2.4.53, updated 19 October 2026, and a creation date of 7 August 2026. 11 HONGDUC publishes it from Vietnam. The manifest asks for the side panel, web requests, tabs, downloads, identity, offscreen documents and unlimited storage, and the package is 39MB.

+3,988 users in one week, from a base of 12. 2

Borderline. At 4,000 users the listing sits under the floor, and at 74 days old it is outside the 60-day window. It stays for a published price and a job narrow enough to check.

Browser-only behavior. Open a page that is playing a video and the side panel lists every HLS and DASH stream the tab has loaded, plays any of them, saves the reference to a library and queues a download with progress. 11

Monetization and MRR scenario. Freemium: Pro at $1.99 a month, plus a one-time $29 lifetime, bought inside the extension rather than on the website. 5 Scenario at the monthly price: 4,000 × 1%–3% × $1.99 = $80–$239 a month. The lifetime tier, at the same paid share, would be $1,160–$3,480 in single sales.

Why Chrome, and where the opening is. The stream URLs exist in the tab's network layer, which is why the manifest asks for webRequest and tabs; a web app receives a pasted address and nothing else. The publisher's own pages warn users to save only media they have permission to download, and that boundary decides the buyer. The realistic customer is somebody archiving a webinar or a course lecture they were entitled to watch, a smaller market than the permission list suggests. A two-week version serves one class of site — course platforms, town-hall recordings — with a $2 subscription and a short permission list.

The extension reports 2,000 users, version 1.0.3, updated 28 September 2026, and a creation date of 15 July 2026. 12 The rating counts disagree inside the sources: Chrome-Stats records 5.0 from 8 ratings, and the store page shows 8 in its header and 58 in its body text. 6 The listing names Michael Lip as the solo developer behind it, with support at a zovo.one address.

+1,997 users in one month, from a base of three. 4

Borderline. 2,000 users, and a listing 97 days old, kept on the same terms.

Browser-only behavior. Open a listing on Zillow or Redfin and a panel appears in the corner: score the home out of five, write a note, and the shortlist grid lines the saved homes up by price, beds, baths and square footage. 12 Content scripts run on those two domains only, and the extension asks for storage and alarms.

Monetization and MRR scenario. One-time unlock: the free tier caps the shortlist at five homes, and Pro at $99 once lifts the cap, adds weighted criteria, CSV export, cross-device sync and a JSON backup. 6 Scenario: 2,000 × 1%–3% × $99 = $1,980–$5,940 in single sales.

Why Chrome, and where the opening is. A house search happens across tabs, on two sites, over weeks, and the panel has to be where the listings are. A standalone app would ask a buyer to paste every address they open. Zillow and Redfin both save favourites; the listing's own pitch is that neither gives you a score or a side-by-side comparison. 6 The listings Chrome-Stats lines it up against are scrapers and lead finders, two of them named for Zillow agents. 12 The weakness is the price. A search that lasts a few weeks turns a lifetime licence into one transaction, which is fine for the buyer and thin for the seller. The same panel pointed at a comparison that repeats — used cars, rentals, colleges — sells more often.

The extension reports 834 users, a 5.0 rating from 2 ratings, version 1.1.0, updated 15 October 2026, and a creation date of 9 October 2026. 13 TeqStars Technologies publishes it from India, and the listing links to 7frames.ai.

+833 users in one week, from a base of one. 2

Borderline. 834 users, with 11 days of history behind it, which is the new-listing window.

Browser-only behavior. Capture a region or the whole tab, annotate it, and the bug report arrives with the console output and network log beside the screenshot. 13

Monetization and MRR scenario. Subscription: free covers unlimited screenshots, four-minute recordings and 20 AI minutes a month. Pro is $7 per seat per month, or $84 a year; Team is $13 and Business $27. 7 Scenario: 834 × 1%–3% × $7 = $58–$175 a month.

Why Chrome, and where the opening is. The console and the network log belong to the browser; a bug report without them is a picture of the wrong thing. The pricing page positions it against Loom, Scribe, a screenshot tool and a bug-capture app in one line, which is a measure of how crowded this corner is. 7 Two ratings and a company publisher mean neither quality nor team size is settled. The pricing is the interesting part: per-seat plans at $7, $13 and $27 assume a team buys for other people, while the first users are individuals with a bug. A two-week version charges one team's handoff channel — a Jira or Linear workflow — at $3 to $5 a seat.

The extension reports 165 users, a 5.0 rating from 4 ratings, and version 1.0.0, updated 12 October 2026. 8 Pick Ads publishes it as a non-trader, and the store marks it as offering in-app purchases.

+153 users in one day, from a base of 12, on a list that measures a single day. 1

Borderline. 165 users, on a listing whose only version dates from 12 October.

Browser-only behavior. Tick chats, shift-click a range, press delete, and the panel drives the chat site's own delete flow through the selection while reporting progress. Exports run to Markdown or a ZIP beside it. 8

Monetization and MRR scenario. Subscription: free deletes 20 chats a day and exports 5; Premium is $6.99 a month or $69.90 a year, bought with a Google sign-in. 8 Scenario: 165 × 1%–3% × $6.99 = $12–$35 a month.

Why Chrome, and where the opening is. The delete runs inside a session the user is already signed into, with no API key and no server of the publisher's own. That is also the risk a buyer has to weigh: the extension works on an irreversible action, its store disclosure says it handles personally identifiable information, authentication information and user activity, and the listing tells users deleted chats cannot be recovered. 8 A two-week version does the same job for one chat site with an undo log beside it, at $3 a month, and sells on the log.

Property Shortlist and Stream Katcher are the two worth starting on. One is 85KB with two permissions and a published $99 price on a job people repeat every few years. The other turned a 12-user listing into 4,000 in a week and charges $1.99 a month for something only a browser tab can see.

Five more listings were checked against this week's lists and left out. Jumpstart Newtab added 9,995 users in a week and Jumpstart Search 19,997, and the publisher states on its own site that both are free with no subscription. 3 Cleaner Searcher, at 8,000 users and +7,996 in a month, routes searches to Yahoo-powered results and comes from Inuvo, a search company in Little Rock, Arkansas. 14 代码狗 (CodePup), at 90,000 users and +89,999 in a month, is a free open-source userscript manager. 15 Monero Wallet · Standalone added 299,835 users in a day to reach 300,000, which puts it above the band. 1

This list runs every Tuesday.
