ProgressionAPI
When you run multiple custom plugins, the real pain is consistency: item IDs, matching logic, shared services, and “why does this behave differently here?”. ProgressionAPI solves that by being the single source of truth for your ecosystem—especially for reliable custom item identity. Less duplication, fewer bugs, cleaner updates.
Highlights:
Central services for your plugin ecosystem
Consistent item identity logic (spec-based workflows)
Built for maintainability and clean multi-plugin setups
Perfect for: servers running multiple custom Progression plugins.
