This file previously carried a scaffold with invented Free / Professional tiers and made-up quotas; those were never published by Ballerina and have been removed. An honest zero is the correct measurement here. plan_count: 0 plans: [] pricing_model: free commercial_notes: >- WSO2 sells commercial products that embed Ballerina — notably the WSO2 Integrator / BI tooling — and those are priced under the WSO2 brand, not under Ballerina's. No pricing is asserted for them in this record. evidence: - url: https://ballerina.io/pricing/ status: 404 - url: https://ballerina.io/ status: 200 note: No pricing link in the site navigation or footer. - url: https://central.ballerina.io/ status: 200 note: Registry front end; no paid plan, quota or billing surface.
