CloudZero
Best for Mid-market and enterprise teams that need per-customer or per-feature unit economics across cloud and AI, and buy through a sales process.
Strengths
- Deep unit-cost engine (cost per customer/feature) and CostFormation®, which allocates 100% of spend regardless of tag quality.
- Broad, mature coverage: AWS/Azure/GCP/Oracle, Kubernetes, OpenAI/Anthropic, and Snowflake, with the AnyCost framework for custom sources.
Limitations
- Pricing is not published — quote-only, with no free tier and no self-serve signup.
- Oriented to larger organizations, so the start is a sales conversation rather than a signup.
