ExtensionBooster is a review marketplace, analytics service and free tool suite for developers who publish Chrome extensions, Edge add-ons, Android apps and Google Workspace apps. Its main promise is that reviews come from real developers who install and use the app, not from bots.
The company lists what it will not do: post fake reviews, promise a rating, use bot accounts or sell listing data. It also describes itself as still growing and says it will not pretend to be bigger than it is.
The product sits between a marketplace and a dashboard. Developers can request reviews, track installs and rankings, and host a public page that lists everything they ship.
A developer first lists an app for free, with no credit card. Each credit pays for one real review and install, and credits can be obtained in two ways: buying a pack, or earning credits by reviewing other developers' apps.
A reviewer installs the app from the store, uses its features and writes a review. The review shows as pending on the store, then goes live.
Before charging anything, the system checks that the review is visible on the listing. Only then is one credit charged for that review, and an undelivered review costs nothing.
The review service is backed by market analytics that track installs, ratings and rankings across stores, along with competitor trends over time. Reviews analytics show the most recent 300 reviews on the Free plan and scale up to unlimited reviews on Platinum, with export on paid tiers.
The developer showcase gives each user a custom handle and a shareable page for all of their apps, with SEO backlinks and automatic share previews. Developers can also cash out credits earned from reviewing.
Six free tools need no account: Find Extension, Download Reviews, Icons Generator, MV2 to MV3 Converter, Screenshot Makeup and Tile Cropper. They cover common publishing tasks such as icon sizes, store tile sizes and review exports.

The platform targets indie developers and small teams, with a free entry plan and low-cost paid tiers. Agencies and publishers with many apps can ask about the Enterprise option.
