9 Chrome Extension Ideas You Could Build In 2024

Coming up with Chrome Extension ideas can be difficult πŸ™„

So, I've listed out a few ideas below that you could use as inspiration when generating your own Chrome Extension ideas. I have purposefully selected a variety of different niches for these ideas just to help get your creative juices flowing.

They're ideas that I've had over the years that I know I'm not ever going to get round to building. Some of them may exist, some may be technically challenging, none have been validated but hey, they're just ideas at this point so I'd recommend you put your own spin on them rather than building them as they're outlined here.

Without further ado, here is the list of Chrome Extension ideas that you could build in 2023:

Chrome Extension Idea #1 - WhatsApp Alternative Chrome Extension

The popularity of WhatsApp as a communication platform is undeniable. Its user base is estimated to grow to over two billion people shortly. It has become one of the most popular messaging apps across different countries and cultures, thanks to its ability to send both text and multimedia messages instantly.

WhatsApp also offers end-to-end encryption, which ensures that your messages and data will be kept private and secure.

However, many people feel that the companion web app version of WhatsApp has limited functionality compared to the mobile app version. Many features are either missing or feel clunky in the web browser version.

With this in mind, check out this popular WhatsApp Chrome Extension WA Web Plus for WhatsApp which has over 1,000,000+ users and over 22k reviews 🀯

With pricing plans at $27.99/Month for Pro and $39.99/Month for Expert, it is mind-boggling how much this extension could be making 🀯

Even if just 1 in 100 users of this chrome extension are on a paid plan (let's take the cheapest tier) that'd be around $280,000 a month ... insane numbers for a chrome extension with no associated server costs!

Now, could you do something similar for another messaging app such as:

  • Signal
  • Telegram
  • Google Messages
  • Wire
  • Viber
  • Messenger
  • Threema

Idea #2 - AirBnB Hosts Chrome Extension

Airbnb is undoubtedly one of the most popular home-sharing websites in the world. With over 4 million listings in 191 countries, it is one of the largest online marketplaces for travellers and hosts alike. Airbnb has connected millions of hosts and travellers around the world, creating a global community that is both vibrant and welcoming.

The popularity of Airbnb has been growing at an exponential rate, and there is no sign of its growth slowing down any time soon. For hosts who rely on Airbnb to make a living, it can be tough to keep up with the multitude of rental listings and bookings in today's fast-paced world. That's where you could create a Chrome Extension to enhance AirBnB from a host's perspective.

Being an AirBnb host can be a lucrative venture, and if your application offers them greater efficiency or ways to market their property better then they'll gladly pay a recurring subscription fee.

Features of this Chrome Extension might include:

  • Screen guests quickly by checking previous reviews left by other hosts.
  • Automatically schedule cleaning requests.
  • Real-time price comparison with similar properties in the area.
  • A calendar feature that shows which dates are available for activities at a glance.
  • AI-rewritten descriptions to make listings more appealing.
  • Automatically price-match certain properties for busy periods of the year.
  • Suggest sale periods for historically quiet vacant periods

Chrome Extension Idea #3 - Ebay Sellers’ Chrome Extension

Ebay is one of the world's most popular online marketplaces, with over 184 million active buyers and 25 million sellers. It is the go-to destination for many shoppers around the world who are looking for great deals on everything from clothing and electronics to furniture and antiques.

The sheer number of buyers and sellers involved in eBay, combined with its focus on customer satisfaction and fast, reliable service, make it one of the most popular choices for anyone looking to start or grow their own eCommerce business.

However, it can be challenging to efficiently run an Ebay business and to keep track of all your sales and orders, not to mention the amount of tedious and repetitive tasks they have to do every day. Could you create a chrome extension that enhances Ebay Seller's experience by allowing them to minimise the amount of tedious and repetitive work they have to do?

Features of this Chrome Extension could include:

  • Re-using elements from previous listings.
  • Looking up sold/completed listings prices.
  • AI-recommended titles and AI-generated persuasive descriptions.
  • AI recommendations for auction vs buy it now listing.
  • Drag and drop auto create listings for easy pricing management.
  • Synchronization with accounting software to automate bookkeeping.
  • Integration with alternative sales channels such as Amazon or Shopify to repurpose listings across multiple platforms quickly.

Chrome Extension Idea #4 - Outlook Chrome Extension

A Chrome Extension to enhance the Outlook web experience, just like other Chrome Extensions have done already for Gmail and other email providers. Whilst Gmail does have 1.5 billion users, Outlook has over 400 million users so that’s more than a big enough user base to target!

Outlook Web has become a central hub for many people's day-to-day activities, from managing tasks and calendars to collaborating with co-workers and staying in touch with friends and family. Despite its popularity, however, some users find that their Outlook experience could be improved by adding features that are currently only available on other email platforms.

Could you look to enhance the users' experience and maybe even replicate the Checker Plus for Gmail Chrome Extension's functionality but for Outlook instead of Gmail?

Features of this Chrome Extension idea could include:

  • Real-time notifications for unread items and new messages.
  • Auto filtering of emails by starred/important folders.
  • Customisable sound alerts for different senders (boss alert tone anyone!)
  • Dictation of emails whilst browsing in other tabs.
  • Outlook Mini-CRM in the browser.
  • Mail merge within the browser.

Chrome Extensions Idea #5 - Runtastic Chrome Extension

Runtastic is used by over 182 million runners and there's plenty of potential to improve the user experience by adding better reporting, filtering and combining the data with related external APIs.

You could potentially build a product around advanced analysis of your running (this is only available in Runtastic Premium currently) and add gamification/streaks to keep runners motivated.

You could draw inspiration from the "Elevate for Strava" Chrome Extension which has over 100,000+ users (and 1,875 excellent reviews) and offer something similar for the Runtastic community.

Features of this Chrome Extension could include:

  • Access to data for all runs (distance, pace, calories burned, etc) and visualizations of your progress over time.
  • Integration with external services like Fitbit or MyFitnessPal to provide even more detailed insights into your fitness data.
  • Connect with friends who use Runtastic to share training updates and compete with each other via leaderboards.
  • Gamification features to help you stay motivated and track your progress over time.

Finally, there are Runtastic communities, such as Facebook and Reddit groups, etc., that you can target to recruit beta testers and for promotional efforts.

Idea #6 - Craigslist Sellers Chrome Extension

Craigslist is an online classifieds platform with over 80 million ads posted every month. It has become a popular choice for millions of people looking to make a living selling products and services, either part-time or full-time. Many of these sellers have been able to create very successful businesses thanks to the flexibility and low cost associated with Craigslist.

However, with this sheer volume of ads, it can be tough for sellers to manage multiple concurrent listings and they must have many tedious and repetitive tasks they have to carry out each day.

Could you build a chrome extension that enhances CraigsList from a seller's perspective?

Features of this Chrome Extension could include:

  • Quick management of listings, including scheduling, editing, and re-using elements of previous listings.
  • AI-powered recommendations on pricing and timing that take into account factors like competition, demand, and seasonality.
  • Real-time notifications to track customer interest and responses.
  • Automated responses to inquiries (potentially via AI)
  • A slick user interface that makes it easy to manage multiple listings at once.

With an intuitive interface and powerful features, sellers would be able to spend less time managing their ads and more time focusing on what matters - selling their products or services πŸ›’

Idea #7 - Amazon Web Services (AWS) Chrome Extension

Amazon Web Services (AWS) is one of the most popular cloud computing platforms in use today. It has become a go-to choice for businesses and developers looking to build, manage, and host applications on the cloud. With its scalability, reliability, and cost-effectiveness, it's no wonder that AWS has become so popular with companies around the world.

According to Amazon, there are more than 1 million active AWS users, from startups to large enterprises. Amazon's platform provides customers with access to an ever-expanding range of services that can be used to quickly build powerful applications and websites.

However, it can also be quite frustrating for some developers due to its complexity, and difficulty in navigating, filtering and managing an enterprise's resources.

Could you create an Amazon AWS Chrome Extension to improve the experience for software developers on the AWS portal?

Features of this Chrome Extension could include:

  • Easier navigation and filtering of different services and products, including the most popular ones.
  • Automatic monitoring of your costs and usage, to help you optimize where possible.
  • Quickly duplicate AWS resources via the Chrome Extension to save typing in repetitive configuration data over and over again.
  • Easy access to important metrics like CPU usage, memory utilization and logs, so you can quickly troubleshoot any issues and stay on top of your cloud infrastructure.
  • Easily start and stop your resources in one place.
  • Overlay helpful widgets on resource capacity, usage and billing information, etc.

Chrome Extensions Idea #8 - RingCentral Chrome Extension

RingCentral is a popular cloud-based CRM/autodialler, with millions of users around the world relying on it for their business needs. It provides a comprehensive suite of tools to help companies manage voice calls, video conferencing, messaging and more.

However, their official chrome extension which has over 200k users, has received alot of damning reviews from users, with many stating that it is poorly designed and difficult to use.

As a result, there is an opportunity to create a new Chrome Extension for RingCentral that is well-designed, easy to use, and provides the functionality that the users need.

Features of this Chrome Extension could include:

  • A reliable bridge between numbers on the webpage and the RingCentral dialler app.
  • A modern design with an intuitive user interface that makes it easy to quickly manage calls and messages.
  • Ability to view full contact profiles of your most frequently-called contacts, so you can easily see their latest updates and details.
  • Accessible from any tab or open window on your device, so you can be notified of important new messages and calls, even if you're working on something else.
  • A flexible notification system that allows you to set up alerts for different types of incoming messages or calls, e.g. urgent vs non-urgent notifications, etc.

The past decade has seen a massive rise in the popularity of fantasy sports leagues. From soccer to basketball to American football and beyond, millions of fans across the world are competing against each other to create their own unique teams and win bragging rights as champions in their respective leagues.

Fantasy NFL is one of the most popular fantasy sports, with millions of fantasy football players, there is a great opportunity for the development of a Chrome extension that offers easy and convenient access to all the latest news, stats, rankings, and expert analysis from across the web for any popular sport.

As another example, check out the popularity of this football based chrome extension for the British Premier League:
