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, Convex leads at 70% fit and $42.18/mo. The two rules doing the work: budget fit (~$42.18/mo is 84% of your $50/mo budget); batteries included (Bundles file storage, realtime — fewer services to glue at team size 1).

Honest weak spot of the pick: proprietary data model — leaving means rewriting the data layer.

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

Why Convex scores 70%

Budget fit (weight 30, our estimate) — ~$42.18/mo is 84% of your $50/mo budget+19.69

Batteries included (weight 12, our estimate) — Bundles file storage, realtime — fewer services to glue at team size 1+8

Exit cost (weight 4, our estimate) — Proprietary data model — leaving means rewriting the data layer-4

Ecosystem maturity (weight 8, our estimate) — growing — our estimate from ecosystem age, docs and hiring pool-1.6

Free-tier runway (weight 10, our estimate) — Free tier exists (1M function calls, 0.5GB database, 1GB file storage, 1GB egress) — a cheap staging/dev lane even after you outgrow it+4

Total (lines sum exactly)26.09

Possible range −64…+64 (sum of active rule weights) · fit % = (total + max) / (2 × max)(26.09 + 64) / 128 = 70%

How the $42.18/mo estimate is calculated

Professional base — includes 0.5GB database storage, 1GB egress$25.00

Database storage overage — 14.5GB over 0.5GB included × $0.2/GB$2.90

Egress overage — 119GB over 1GB included × $0.12/GB$14.28

Note — Per developer. Pro includes more than the free quota, so this overage model is a conservative upper bound$0
