Mongo Playground

Mongo playground: a simple sandbox to test and share MongoDB queries. Try it online : mongoplayground


Size limitations

This playground has several limitations:

  • a database can't contain more than 10 collections
  • a collection can't contain more than 100 documents
  • all collections are capped to a size of 100*1024 bytes, see mongodb capped collections for details


Currently, the playground can run only find() and aggregate() queries

shell regex

Currently, shell regex doesn't work in query.

so instead of

  "k": /pattern/


  "k": {
    "$regex": "pattern"


This playground is heavily inspired from The Go Playground

Editors are created with ace, and the documentation is styled using github-markdown-css

You can’t perform that action at this time.
