Estimate cost, check migrations, compare prices, inspect bills, reason about cache safety, BYOK, routing health, substitutions, and receipts before you send production traffic.
Tools
Start with a diagnostic, not a free-token giveaway.
These tools run without anonymous model calls and are designed for teams already comparing AI API cost, reliability, and auditability.
