  terms:
    - term: Traffic Capture
      definition: >-
        The process of recording real API requests and responses from a
        production or staging environment, including full payload bodies,
        headers, authentication tokens, and timing metadata.

        - Sidecar
        - Proxy

    - term: Traffic Replay
      definition: >-
        The process of replaying previously captured API traffic against a
        target service in a test environment to reproduce real-world load
        and behavior deterministically.

        - Load Testing

    - term: Snapshot
      definition: >-
        A saved collection of captured API traffic (requests and responses)
        used as the input for a traffic replay. Snapshots preserve exact
        production scenarios for reproducible testing.

    - term: Service Virtualization
      definition: >-
        The simulation of backend API dependencies (databases, third-party
        services, microservices) using captured traffic responses, allowing
        isolated testing without access to real downstream systems.

        - Mocking
        - Traffic Capture

    - term: Mocking
      definition: >-
        A form of service virtualization where Speedscale automatically creates
        response simulations from captured traffic, removing the need for real
        backend services during testing.

        - Proxymock

    - term: Proxymock
      definition: >-
        Speedscale's local-first traffic replay and mocking tool, available as
        a free desktop CLI. Proxymock captures traffic and mocks upstream
        dependencies without requiring cloud connectivity.

        - speedctl

    - term: speedctl
      definition: >-
        The Speedscale command-line interface for data collection, traffic
        replay, schedule management, and infrastructure control. Available
        for macOS, Linux, and Windows.
      related:
        - CLI
        - Proxymock

    - term: Sidecar
      definition: >-
        A proxy container deployed alongside an application in Kubernetes to
        intercept and capture all inbound and outbound API traffic without
        modifying the application code.

        - Traffic Capture
        - Kubernetes

    - term: Test Report
      definition: >-
        The output of a Speedscale traffic replay run, showing which API calls
        succeeded, failed, or deviated from expected behavior, including
        latency and error rate metrics.
      related:
        - Traffic Replay
        - Performance Assertions

    - term: Performance Assertions
      definition: >-
        Configurable thresholds applied to replay results, failing a test if
        error rates, latency, or throughput exceed defined limits.

        - Test Report
        - Load Testing

    - term: PII-Safe Replay
      definition: >-
        A Speedscale feature that automatically detects and masks personally
        identifiable information (PII) in captured traffic before replay,
        ensuring compliance when using production data.

        - Traffic Capture
        - Traffic Replay

    - term: Load Testing
      definition: >-
        A type of performance test where Speedscale replays production traffic
        at scale to validate application behavior under realistic load conditions.

    - term: MCP Integration
      definition: >-
        Speedscale's native support for the Model Context Protocol, enabling
        AI coding agents (Claude Code, Cursor, GitHub Copilot) to access
        production traffic context when generating and validating code.
