Verified limits

What we can show
for MongoDB Atlas

Each row pairs a number with its official source and last verified date. Where the registry has not yet produced a limit value, the metric appears below the table as Not certified yet rather than a guess.

Free clusters

Capacity (grows forever)

Free clusters measures the clusters reported by the provider. It never resets automatically. Treat it as a cumulative capacity; once full, it does not reset automatically.

Coverage

What we can read
and what we cannot

BeforeRed tracks a small, deliberate set of capabilities per provider. The table below shows the registry state for MongoDB Atlas today. A Certified row is one we can defend in front of a customer; the other states are honest about what is still in progress.

How BeforeRed reads
that number

The integration page for this provider explains the connect flow, the read-only OAuth scopes we request, and what we do once a sync finishes. It is the bridge between this limit and the dashboard the user sees.

If a number looks wrong

Tell us. A limit that has drifted between the provider and this page is a high-priority fix and we treat it as one. If a row is missing a source, that is a publish-grade bug in our eyes too.
