A useful distinction
Free does not mean one thing
Each guide separates durable free plans, limited free tiers, open-source or self-hosted paths, trials, and paid-only products. The label is only useful when the allowance and tradeoff are visible beside it.
The boundary
Tools provide evidence. Diagnosis is separate.
Analytics, research, and experimentation tools answer different questions. If you still need to determine what is wrong with the landing page itself, Nebula can inspect its observable conversion conditions.
