Introduction & Dependency Graph ​

diid is an API connection management platform designed to map, track, and protect API dependencies across services and teams.

diid maintains a live, contract-aware dependency graph of your services, preventing unintended breaking changes to downstream consumers.

Core Concepts ​

A diid workspace consists of three core elements:

  • Projects: The applications, microservices, frontends, or message brokers in your system.
  • Specifications (Specs): The API contracts (OpenAPI, AsyncAPI, GraphQL, SOAP) defining how a project communicates.
  • Dependencies: Explicit relationships indicating that one project consumes another project's API or message channels.

The Dependency Graph ​

The main dashboard provides an interactive dependency graph representing your ecosystem:

  • Nodes represent projects.
  • Edges represent directional dependencies between producers and consumers.

The graph updates automatically as projects, specifications, and dependencies change.

Breaking Change Indicators ​

When an upstream spec is updated with breaking changes, diid flags affected nodes and edges until approvals are granted:

  • Producer Nodes: Display a warning counter indicating pending consumer approvals.
  • Dependency Edges: Highlight affected links between consumers and producers.
  • Project Cards: Show warning badges for projects impacted by pending contract changes.
