The decision, in plain words

For a solo builder at 50,000 monthly active users and a $50.00/mo budget for the database slot, MongoDB Atlas leads at 53% fit and $56.94/mo. The two rules doing the work: ecosystem maturity (established — our estimate from ecosystem age, docs and hiring pool); free-tier runway (Free tier exists (512MB storage, shared CPU/RAM, ~100 ops/sec cap) — a cheap staging/dev lane even after you outgrow it).

Honest weak spot of the pick: ~$56.94/mo is 114% of your $50/mo budget — over it.

Generated from the calculation above — every number traces to the sourced data; nothing here is written by an AI making things up.
