80,000 users for free, $7 once for 324: five Chrome extensions that moved
Five Chrome extensions that gained users in the week to 13 October 2026 - a free Gmail attachment viewer built for Brazilian government paperwork, a fleet route planner charging $69 a month, a Facebook ad-library downloader priced in CFA francs, a $9.99 LinkedIn hover and a $7 form filler - each with its movement window, its price or the reason there is none, and a two-week clone angle.
Every extension that moved inside this week's user band is a fix for a limit the host platform set and left standing.
Gmail hands you an HTML attachment as raw code. Google Maps stops a route at ten stops. The Facebook Ad Library has no export button. LinkedIn shows a job title and nothing about the company behind it. A web form forgets every answer the moment you submit it.
Each of this week's five movers lives inside one of those gaps, and four owners have put a price on lifting the limit. The fifth is the biggest mover of the week, and it charges nothing.
That is the news. The Gmail attachment viewer gained 79,000 users in seven days and sells nothing at all, while every extension here with a published price sits under 1,000 users. The store rewards the free fix first, which is where the opening is.
The same shape waits in the corners next door: other public portals mail out documents that land as code, other free planners cap a route, other ad networks publish a library with no export, and other trades want a LinkedIn profile annotated before a call.
How the numbers are read
Install counts and movement come from Chrome-Stats, read on 13 October 2026 beside each extension's live Chrome Web Store listing. 1
Six Chrome-Stats lists are the entry point, and each sorts by the size of a change. 2 A percentage list is therefore led by a listing that jumped from one user to a thousand, while an extension adding 3,000 users never appears; the absolute lists this week held only million-user apps. An extension between 5,000 and 200,000 users shows up on neither unless its move is unusually large.
The filter for that band is each extension's own trends page, which carries a one-day and a one-week change. 3 Every figure below is quoted with its window and its base, because a percentage without its base hides the thing that matters.
No public 30-day install percentage exists for any of the five, so movement is given as one-day, one-week and one-month absolute changes, each named where it appears. Four picks are monetized.
Each revenue figure is a scenario built the same way: current users × an assumed paid share of 1–3% × the published price. Where the money is a one-time purchase, or nothing is published, the range is labelled instead of forced into a monthly number.
Three picks sit below the 5,000-user floor and say so inside their own profiles. All three were listed within the last 60 days, which is the rule that lets them in.
This week's five, at a glance
| Extension | Users, 13 Oct 2026 | Movement | Price | Illustrative MRR | Publisher |
|---|---|---|---|---|---|
| HTML Attachment Viewer | 80,000 | +79,000 in 1 week 3 | Free, no price | Unavailable | individual, Brazil |
| Google Maps™ Route Optimizer by Routing24 | 7,000 | +2,000 in 1 week; +6,991 in 1 month 4 | $69 or $199 a month for the web planner 5 | $2,415–$9,660 | Routinghub LLC (company) |
| Clolayn Radar | 1,000 | +999 in 1 week 6 | 15,000 CFA francs a month, about €23 7 | €230–€690 | individual, "Clolayn" |
| Prism Intellivent | 769 | +766 in 1 week 8 | $9.99 a month 8 | $7.70–$23 | Taleb Kabbara LTD (company) |
| AnswerKeep | 324 | +324 in 1 week 9 | $7 once | $23–$68 one-off | individual, no name published |
"Unavailable" means the publisher sells nothing, which for this week's biggest mover is the interesting part.
Loading chart…
Installs on 6 October 2026 against installs on 13 October 2026, on a linear axis, from Chrome-Stats 1 and 3 read that day. A bar of zero means the listing did not exist a week earlier. The four priced picks are the short bars on the right, and their height is the week's finding.
1. HTML Attachment Viewer: 80,000 users and nothing for sale
The extension reports 80,000 users, a 5.0 rating from 3 ratings, and version 2.3.2, updated 7 October 2026. 10 Chrome-Stats dates its creation to 22 September 2026 and shows it running on one host, mail.google.com, where it modifies the message view. 11 Ataide de Paula Paiva, an individual developer in Brazil, publishes it and states that it is independent of the Minas Gerais state government. 10
+79,000 users in one week, from a base of 1,000 on 6 October, and an overall store rank that climbed 26,046 places to #2,687. 311 It is the only extension inside the 5,000–200,000 band on either of this week's one-week lists. 1
Open an email from a Brazilian government system and the HTML attachment normally arrives as a download or a wall of markup. The extension renders it as a formatted document inside the Gmail tab, strips the scripts and forms inside it, and keeps a per-sender list of who may open without a prompt. 10
Nothing is for sale: no purchase label, no price, no account. The developer files himself as a non-trader, the store's term for a publisher who sells nothing to consumers, so MRR is unavailable for the plain reason that no product exists to price. 10 This is the second week in a row that the biggest in-band mover charges nothing.
A mail client's own page is the only place its attachment can be rendered as a document, so the job belongs to the browser tab. Demand needs no interpretation at 80,000 users in three weeks; the quality evidence does, at three ratings on a tool whose users are civil servants opening official memos.
Nobody has asked them for money, and what they would pay is unmeasured. The two-week version picks one document portal — a state procurement system, a court filing service, a school district — and charges the clerks who open its files all day, at a price low enough to expense without approval.
2. Google Maps™ Route Optimizer by Routing24: a 500-stop limit and a $69 upsell
The extension reports 7,000 users, a 5.0 rating from 19 ratings, and version 0.1.2, updated 19 September 2026. 12 Chrome-Stats dates its creation to 9 September 2026 and shows it holding side-panel and scripting permissions across every Google Maps domain. Routinghub LLC publishes it, a company rather than an individual developer. 13
+2,000 users in one week, from 5,000 on 6 October, and +6,991 in one month, from a base of nine. 4 The month count covers the whole period and the trends page counts seven days, so most of the month's gain arrived in its final week.
Paste a list of stops into the side panel and the extension reorders them for time or for distance, which Google Maps itself stops doing past ten stops. The result opens back in Google Maps as consecutive ten-stop legs, so the dispatcher keeps the interface they already know. 5
The extension is free. The paid product is the same company's web planner: $69 a month for commercial use, $199 for the pickup-and-delivery tier, and a free non-commercial plan below both. 5
Scenario: 7,000 × 0.5%–2% × $69 = $2,415–$9,660 a month. The paid share is lower than on the consumer picks below because a route planner is bought by an operation, and the buyer has to move a whole schedule into it.
The ten-stop limit belongs to the Google Maps page, and the stop list exists nowhere else; a standalone planner would make the dispatcher retype every address. The gap in the model is the distance between free and $69 a month, which leaves the one-van courier with nothing to buy. A two-week version serves that buyer: one vehicle, one day, the same side panel, a price under $10.
3. Clolayn Radar: a subscription priced in CFA francs
Clolayn Radar reports 1,000 users, no ratings, and version 2.6.0, updated 5 October 2026, with the listing written in French. 14 Chrome-Stats dates its creation to 3 October 2026, ten days before this issue, and "Clolayn" publishes it, an individual with a Gmail contact address. 15
+999 users in one week, from a base of one, with 213 of them arriving in the final day. 6 At 1,000 users it sits below the floor. It earns its place by going from a first listing to a priced product in ten days.
A page of winning ads in Facebook's Ad Library has no download button. The extension adds one, files the ad's video or image into a folder in the user's Clolayn account, and overlays best-seller and live-ad data on competing Shopify and WooCommerce storefronts. 7
Three days are free with no card, then 15,000 CFA francs a month — about €23 at the fixed peg of 655.957 francs to the euro. 716 Checkout runs on Wave, Orange Money, MTN, Moov or a card, which is the local rails rather than Stripe. Scenario: 1,000 × 1%–3% × €23 = €230–€690 a month.
The Ad Library is a logged-in page, and the download has to happen inside the session the advertiser already has open. The price tag is the more interesting half: a Western-style subscription sold in West African francs with mobile-money checkout, to merchants who sell cash-on-delivery. The same page exists in markets nobody builds for, each with an ad library that has no export and sellers who already pay for tools.
4. Prism Intellivent: $9.99 a month for a LinkedIn hover
Prism Intellivent reports 769 users, no ratings, and version 1.0.32, updated 6 October 2026. 17 Chrome-Stats dates its creation to 27 September 2026 and shows content scripts on linkedin.com beside the publisher's own domain. Taleb Kabbara LTD publishes it, a company registered in the United Kingdom. 8
+766 users in one week, from a base of three. 8 At 769 users it is the second borderline pick, below the floor, and it arrives with a published price and a trade narrow enough to name.
Hover a name on LinkedIn and the extension shows which companies and which sports-business events a public source ties to that person, with the source kept beside each claim, on the profile page. 8
Five lookups a day are free and reset at midnight UK time; the listing prices unlimited hovers at $9.99 a month. 8 The workspace behind it sells memberships at $97 and $297 a month, so this extension sits at the cheap end of a high-priced ladder. 18
Scenario: 769 × 1%–3% × $9.99 = $7.70–$23 a month. At this size the figure is not the point. The shape is: a two-person team can assemble vertical data, put a price on it, and sell it to a trade that already buys research.
The context has to appear while the reader decides whether to send a message. The trade matters more than the tool. Sports-business dealmaking has conferences, sponsors, and a small number of people who track both, and the extension sells to that group by name — a position a general-purpose contact finder cannot take.
5. AnswerKeep: $7 once, 324 users, one week old
AnswerKeep reports 324 users, no ratings, and version 3.0.0, updated 6 October 2026, the day Chrome-Stats first recorded it. An individual trading as "answerkeepsupport" publishes it, with support over a Gmail address. 19
+324 users in one week, 321 of them in the final day, from a base of zero because the listing did not exist a week earlier. 9 It is the third borderline pick, and the new-listing rule is the only reason it qualifies.
A form asks the same eleven questions the user has answered on ten other sites. The extension keeps the answers in the browser, previews which fields it will fill before touching them, and leaves submit to the user. 20
One profile is free, with answers stored locally and exportable as plain JSON. Pro is $7 once, unlocked by a licence key sold through Gumroad, and adds separate personal, business and client profiles plus encrypted backups. 1921
A one-time purchase yields a one-off figure rather than recurring revenue: 324 × 1%–3% × $7 = $23–$68 in single sales, with every later buyer adding to the total without adding to a monthly number.
The answers have to be typed into somebody else's page, and storing them locally is what separates this from a cloud form filler.
The price carries the same weakness: a one-time $7 sale needs a large funnel, and store search traffic is the only funnel here. A two-week version points the same local storage at one recurring form — a permit renewal, a monthly filing, a clinic intake — and charges for the last step rather than the first.
The two-week shortlist
Clolayn Radar and Routing24 are the two worth starting on. Both publish a price, both have a base small enough to catch, and neither needs infrastructure the reader has to invent: one export button on a logged-in page, and one side panel that answers a limit the platform refuses to lift.
Three in-band movers were checked and set aside. PDF Search Helper took 10,000 users and added 9,978 in a month by setting Yahoo as the default search engine and adding a PDF filter 22 — the same search-referral model this list covered on 6 October.
cs2vision, a FACEIT interface tool, gained 3,933 users in a week to reach 4,000 and publishes no price. 23 ARC'TYNOVA Desk, a WhatsApp Web translation and CRM sidebar for export teams, reached 356 and publishes no price either. 24
This list runs every Tuesday.
