Important restrictions

The M0 Free tier is ongoing but constrained to development/learning, with region, throughput and feature limits. A separate no-signup Ephemeral M0 cluster is NOT durable: it pauses after 2 days and is deleted after 7 days unless claimed. Do not confuse ephemeral signup flow with a claimed Free Atlas cluster or a paid Flex cluster.
