Key Features
    • • MCP server for AI coding tools
    • • Structured JSON decision records
    • • Semantic decision search

    Mockzilla - Pros & Cons

    Pros

    • ✓Simplest spec-to-mock workflow available — git push is the only step
    • ✓PR environments solve 'mock out of date' and 'works on my machine' problems
    • ✓Only API mocking tool with native MCP support for AI agents
    • ✓148,000+ MCP installs demonstrate strong developer adoption
    • ✓Spec-driven approach keeps mocks automatically in sync with API contracts

    Cons

    • ✗Hosted simulations require a Mockzilla account (not fully self-hosted)
    • ✗Limited to REST APIs — no GraphQL or gRPC mocking
    • ✗GitHub-centric workflow — GitLab and Bitbucket support unclear
    • ✗Complex dynamic response logic may require custom configuration beyond specs
    • ✗Newer platform — long-term stability and maintenance commitment unproven

    Decision Node - Pros & Cons

    Pros

    • ✓Semantic search finds relevant decisions even with different terminology
    • ✓Works across all major AI coding tools via MCP
    • ✓Local storage keeps sensitive decisions on-premises
    • ✓Visual UI helps teams explore decision relationships
    • ✓Structured format prevents decisions from becoming unstructured brain dumps

    Cons

    • ✗Requires a Gemini API key for vector embeddings (adds dependency and cost)
    • ✗Only useful if the team consistently records decisions — needs adoption discipline
    • ✗Local-only storage means no built-in team sync or cloud collaboration
    • ✗Vector embeddings are Gemini-specific — no choice of embedding provider
    • ✗No integration with existing decision documentation tools (ADR tools, Notion, etc.)
