User reviews

Monosearch is a customizable and convenient Chrome extension popular for price comparison and tracking seller inventory and sales data. Users appreciate its helpful features and occasional responsive support. However, many report persistent issues such as settings resetting after reboot, core features restricted to paid Pro plans, bugs causing missing buttons or broken functions—especially on Mac—and slow or absent developer responses. Some also experienced repeated billing problems. While it remains useful, recurring technical and customer service challenges hinder user experience.

Pros

Customizable and user-friendly features making it convenient to use.
Helpful for price comparison across online marketplaces.
Provides useful data like stock levels, sales volume, and price history.
Convenient for monitoring Amazon seller inventory and sales information.
Appreciated improvements and responsive support when issues are addressed.

Cons

Settings reset after computer restarts with problematic import/export of preferences.
Essential features like stock display and graphs moved behind a paid Pro version, limiting free users.
Frequent issues with extension functionality breaking or buttons/docks disappearing, especially on Mac.
Delayed or no developer response to multiple user reported bugs and concerns.
Multiple unexpected charges and billing problems reported by users.

機能自体はカスタマイズもできるしとても使いやすいです。ただ、パソコンを再起動するとリンクボタン設定が全てリセットされてしまいます。設定情報をエクスポートしておいて、そのデータをインポートしても反映されません。拡張機能を再インストールしてからインポートすれば反映されますが、なかなか手間がかかります。何度か運営さんに問い合わせていますが、改善されていません。

価格比較しやすいですが、楽天のiPhone13をAmazonで調べたら鉄アレイ出てきてウケた。

モノサーチをオンにした状態で、Amazonで買い物をすると、全てのセラーから全ての在庫をカートに入れてしまう現象がおきてます。 ↑以前も投稿したんですが、全く解消されてませんね。

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Monosearch requires a few sensitive permissions. Exercise caution before installing.
