Downloading MongoClient 2.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available.
Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free software for Mac OS X was originally created by Sercan Özdemir. The application lies within Developer Tools, more precisely DB Tools.
From the developer:
MongoClient is a MongoDB management tool for Mac users. The program allows you to easily download/upload files into your grid-fs buckets, manage your users and roles without writing any shell command, monitor your database with charts, manage, dump and restore database, and more.
You may want to check out more software for Mac, such as Valentina Studio Pro, which might be similar to MongoClient.
