Compare MongoDB indexes across clusters in seconds

Your query is fast in staging and slow in production. Nine times out of ten the difference is an index that exists in one place and not the other — and finding it usually means dumping the index list on both sides and diffing by eye.

There’s a better way to see it.

Indexes, side by side

DataStudio’s Index Compare lays the indexes of one database next to another and shows you exactly what differs — indexes that are missing, extra, or defined differently. Instead of guessing why prod is slow, you see the gap on a screen, before it costs you a 2am page.

How it works

• Two databases, one view — compare staging vs prod, tenant vs tenant, before vs after.
• Missing, extra, mismatched — every index difference, called out clearly.
• Per collection — see exactly which collection is missing which index.
• Catch drift early — find the gap during review, not during an incident.

Who it’s for

Platform engineers chasing a performance difference between environments, and anyone who’s ever shipped a migration that forgot to bring the indexes along.
