Software opportunity: Thousands of Chrome Extensions are about to disappear

cover image

There are over 132,000 extensions available for Google Chrome.

Recently, Google started showing this message on many pages in their Chrome Extension Store:

Warning message on a Chrome Extension

Read on to learn why this is great news if you're a bootstrapped founder.

Why is Google displaying this message?

On July 10th, Google published a blog post titled, "What's happening in Chrome extensions?"

In this post, they announced that they are "warning users that Manifest Version 2 extensions will soon go away" (by showing messages like the one above).

Think of an extension manifest like an operating system version. "Manifest v2" extensions were like "Windows 10," and Google now wants everyone to switch to "Windows 11."

Google started phasing out Manifest v2 extensions back in 2022. This is the "final countdown," and Google is essentially saying: Either upgrade or get out of our store.

Many extensions will be kicked out by the end of 2024

I've been browsing through the Chrome Web Store and found that this message appears on many extensions for almost every keyword I type.

These aren’t just obscure extensions with a few users; many have tens of thousands of users.

Here are a few examples:

ext1ext2ext3

The developers of these extensions have likely ignored two years of Google’s emails urging them to upgrade to Manifest v3. They also spent weeks ignoring this message on their extension page. It's safe to say that these extensions will be kicked out from the Web Store by the end of 2024.

The opportunity for bootstrapped founders

Find a popular extension that's about to "expire" and create a version of that extension in Manifest v3.

Chrome extensions are open-source by default, which means you don’t have to start from scratch; you can easy inspect the extension’s source code.

Additionally, you can use an AI tool like Claude or ChatGPT to help you create a V3 version of the extension (feed the source code and ask for a refactor). I’ve found that Claude is particularly good at creating boilerplates and can code the logic/interface for any Chrome extension with minimal errors.

Once you create the extension (and do some basic promotion), Google will likely start recommending it under the "Try one of these alternatives" section for V2 extensions:

try these v3 manifest extensions

Good luck!

    Hm, I tried it with one extension and it got immediately flagged and removed from the store. I think it detected it was merely a copy. I think you'd have to invest much more time in making it unique so it gets past these checks. Interesting idea though, thanks for sharing.

    1. 1

      Oh interesting, so you just copied it and updated the manifest + fixes?

  2. 1

    The source of most of the extensions is compressed and obfuscated. Good luck being able to understand this kind of code.

    This would be a waste of time if you want to take this shortcut for the indie idea.

    Many issues were mentioned in the comments: copyright, auto-removed by Chrome as duplicate, license, and more.

    The extensions themselves could be hard to migrate from Manifest v2 to v3. That's why some of the owners are not doing it. This is the reply I got when I personally emailed the owner of one of the plugins.

    I think the niche of profiting from chrome extension might be alittle harder than for example having a software

    ATTENTION: No, they are NOT OPEN-SOURCE. Yes, you can look at the source, but actually refusing it may get you into legal trouble. What the SO link actually says it that the source can be looked at. Not that they are FOSS

    Thanks for the idea, Darko !

  7. 1

    nice article! my ask is this: how does copyright work here? someone would be working on an old code by somebody else and earning money off of it

  8. 1

    This is a good approach, but it certainly can't be a direct copy of the original plugin, and more innovation is needed

  9. 1

    I looked at the extensions you gave as examples and I don't see any notification.

    It's a great opportunity I have already built 2 extensions on Chrome and have got decent visibility. Decided to offer Chrome extension development as a service as well. This is going to be a boost

    1. 1

      How do offer chrome extension development as a service? Which platform do you you use? I want to know more if you may!

      1. 1

        I find SaaS companies who want to build a Chrome extension as a free tool or would like to build an internal tool for data scrapping.

  11. 1

    Great news to me as an extension developer. If anyone interested in building their extension please ping me

    "Big changes are coming to the Chrome Extension Store! With Google phasing out Manifest Version 2 extensions, there's a huge opportunity for bootstrapped founders to step in. By updating popular extensions to Manifest V3, you can tap into a market that's about to lose many existing players. Time to get coding and seize the moment!

  13. 1

    what a timely post! i'm building a chrome extension to help web developers intercept network requests and modify the responses. check me out at @joeyjiron06 on X / twitter

    Google is phasing out Manifest V2 extensions in favor of Manifest V3. Popular extensions at risk of removal by the end of 2024 offer an opportunity for founders to develop updated V3 versions. For more details, read Google’s blog post What's happening in Chrome extensions?.

  15. 1

    There are several issues to just updating the manifest and/or making minor changes to the code, and uploading them as is.

    1. Usage: Who is ever using these extensions? I’d assume that any decently popular extensions are well maintained, or else no one will use them anyway. Isn’t it?

    2. Copyright: How does the copyright look like - in the old and the new extension?

    3. License: What’s the license under which the extension was published? Did you make any changes to that, or does the license allow you to clone and modify?

    4. Attribution: Did you attribute your extension to previous developer well enough?

    5. Flagged by Store: Google / Chrome store has advanced tooling to detect extensions with over X% of code duplication, and it’s highly likely that the extension gets flagged as "copy".

    It can take substantial effort to make your extension as a "true alternate".

    This is best idea but very workable for anyone

    <p>This is a golden opportunity for bootstrapped founders! With many popular Chrome extensions set to be phased out, creating Manifest v3 versions can open new doors. Use tools like Claude or ChatGPT to refactor code and capitalize on Google's push for upgrades.

    This post is mostly hype, encouraging those with no prior intentions to get into browser extensions to jump in.

    I would be really interested to see where are the valid examples of profitable extensions that are about to expire?

  19. 1

    Oh no! It's disappointing to hear that Google is removing some of my regularly used extensions.

  20. 1

    Productivity Owl and Decreased Productivity do not have those notices for me. They seem fine.

    Do you have any examples which are actually v2?

    Any extension which is generating recurring revenue would surely have active maintenance, and if this is super simple I.e. Use GPT and it’s easy, the maintainer who is earning revenue would do that easily and have vested interest in doing so, no?

    I can’t see many valid examples that you mentioned.

  21. 1

    Given the impending removal of Manifest v2 extensions from the Chrome Web Store, what strategies would you recommend for bootstrapped founders to effectively promote their newly upgraded Manifest v3 extensions and capture the user base of deprecated extensions?

  22. 1

    This is a good idea, didnt know chrome extensions are open source, but cant the dev of these soon-to-expire app from just upgrade?

  23. 1

    This is a clever idea. Sharing it!

  24. 1

    This is an excellent opportunity! To be able to move quickly and capitalise on this without wasting time building a billing system, I would recommend my Chrome extension billing platform - BrowserBill. You can literally start accepting payments in 5 minutes, we have step-by-step tutorials on how to set it up as well as example code that you can use.

  25. 1

    I've been saying this for a while, Chrome extensions are an underappreciated niche, especially with many expiring: https://www.indiehackers.com/post/google-is-deprecating-thousands-of-extensions-which-means-tons-of-juicy-product-opportunities-b700b527d3

    Browser extension are also a good way to start indie hacking: they're easy and free to create and publish, and have chrome store distribution. https://www.indiehackers.com/post/why-browser-extensions-are-a-good-way-to-start-indie-hacking-d534627540

    The only pain in the butt was adding payments to them, but I made [a service](https://extensionpay.com/) that does that and now use it in my own extensions and it's super easy.

    Nice opportunitty you saw there. Thanks for sharing that opportunity. My question here would be how to monetize with this kind of product. Isnt the ticket pretty low? I understand you can manage multiple chrome extensions at once, but at least in my social circle, i havent heard of a lot of people who actually purchased a chrome extension. Any thoughts on this?

    1. 1

      There are lot of saas businesses who have built on top of chrome extension - ZoomInfo, Phantom buster, Asnap and moreee

  27. 1

    Great read! Looking forward to the next!

  28. 1

    Thank you, really useful.
    Waiting for the part 2 of your Post "API arbitrage: How to quickly
    test hundreds of product ideas
    " where you mention this "Part 2 of this post will focus on how to market your API."
