Depends
depends.cc is a lightweight, API-first dependency state service for tracking the status of nodes (services, tasks, deploy steps) and their dependencies. Nodes have states (green, yellow, red), and the effective state of a node is the worst state across itself and its transitive dependencies in a directed acyclic graph (DAG). It passively receives state updates via API or CLI, computes graph changes, and fires webhooks or emails on effective state transitions—no polling or outbound crawling.
