If your Claude usage is enterprise multi-tenant llm proxy and you're comfortable with docker self-host, One-API is purpose-built for that shape. 32k GitHub stars if that matters to you.
If your Claude spend spans multiple workload types (support automation, agent loops, code review, content drafting, daily coding) or you want to audit your bill before you commit to any cost-reduction tool, AIUsage gives you the number first. No CLI install, no platform dependency, no code rewrite.
One-API is enterprise API-management infrastructure. AIUsage is a focused audit + cost-reduction layer for Claude API traffic.
