I wrote an application (in PHP, JS, HTML and CSS) that allows you to administrate a MongoDB database via a Web browser. Project name is: MongoDB PHP GUI. It is open-source and free. Its features are:
- Create databases and collections.
- Create, read, (in place) update and delete documents.
- Query with JSON or SQL. Autocompletion is available.
- Export output to JSON.
- Create and delete indexes.
- Work on any device thanks to its responsive design.
