  • They diverge on capability: GraphQL Playground covers Query building, Skopeo covers Remote inspection.

Apollo uses volume-based tiered pricing for requests: first 250M operations cost $5.00 per million plus $2.00 for performance add-on; next 750M operations are $4.25 per million plus $1.50 add-on; additional tiers scale down to $3.00 per million plus $0.50 add-on for operations over 5 billion.
