Why trust the numbers?

Official sources, dated

Every price traces to the vendor's official pricing page, stamped with the date we verified it.

Deterministic math

Costs and rankings are computed by code and locked by hand-computed tests — AI never invents a number.

Estimates labeled

Fit weights are our estimates, marked as such, with the basis shown on every scoring line.

Read the methodologyView pricing sources

StackSays is a developer-tool decision engine. It compares databases, hosting, authentication, email APIs, AI models and payment providers using user-supplied usage, budget and technical constraints. Prices come from dated official vendor sources; costs are calculated by deterministic code, while fit scores are labeled estimates.
