I haven't liked any of the Mongo tools out there and using mongo from the CLI is unwieldy, especially for complicated aggregations. Mongo Playground is themed from the GraphQL Playground, which was based upon GraphiQL.

• Supports queries using latest MongoDB Driver 3.1
• Connects to any MongoDB server using mongodb or mongodb+srv URLs
• Drop down lists all available methods
• Auto-populates list of collections to query
• Syntax highlighting and pretty printing of response data, including errors
• Helpful auto-formatting and syntax highlighting in textarea
• Tabs for running multiple simultaneous queries
• Use of local storage so you can leave, come back later, and continue where you left off
• Nice interface 👍

git clone https://github.com/Perceptive/mongo-playground.git
npm install
npm start

Then navigate to http://localhost:4000.
