Pick the control point for your AI spend with facts, not vendor blogs.

The Token Ledger is a neutral, sourced database of AI gateways and AI FinOps tools. We rate each one on what a FinOps lead needs: hard budgets per team and key, chargeback tags, FOCUS export, EU data residency and public pricing. Every claim links to its source.
