Features

• Network Traffic Replay Tools - Captures live HTTP traffic from production and re-injects it into target environments for system validation.
• HTTP Traffic Shadowing - Mirrors live HTTP traffic from a production environment to a test system to validate changes with real world data.
• Traffic Capture Frameworks - Listens for incoming HTTP requests on a specified address and captures payloads for redirection and mirroring.
• Pod Traffic Mirroring - Intercepts network messages from specific pods using label selectors and namespace filters within a Kubernetes cluster.
• Payload Rewriters - Rewrites URLs, headers, and parameters using regular expressions and hashing to transform production traffic.
• Traffic Steering Plugins - Directs captured network data between input sources and output destinations using a pluggable architecture.
• Network Testing - Captures and mirrors traffic from specific pods using label selectors to test microservices within a Kubernetes cluster.
• Traffic Playback Engines - Replays recorded network requests while respecting original timing and delays to simulate real-world traffic patterns.
• Request and Response Transformers - Provides a transformation engine to modify URL paths, headers, and body parameters during traffic replay.
• Traffic-to-HTTP Ingestors - Consumes messages from Kafka topics and transforms them into HTTP payloads for playback into a target environment.
• Elasticsearch Exporters - Indexes captured network traffic into an Elasticsearch instance using custom URIs and authentication.
• Kafka Stream Exporters - Streams captured network payloads to Kafka topics as raw strings or structured JSON objects.
• Traffic Bridge Pipelines - Provides a data bridge that streams captured network payloads to Kafka topics or ingests messages for HTTP playback.
• Payload Pattern Rewriting - Modifies URLs, headers, and body parameters on the fly using pattern matching to sanitize or redirect traffic.
• Traffic Throttling - Controls the data processing rate for plugins to maintain system stability and prevent destination overload.
• External Command Piping - Routes captured traffic through external system commands or binaries for custom authentication and filtering.
• File-Based Replayers - Loads previously recorded HTTP requests from files and replays them while maintaining original request ordering.
• Non-HTTP Protocol Replay - Processes and mirrors non-HTTP traffic, such as Thrift or ProtocolBuffers, to test specialized backend services.
• TCP Traffic Replayers - Sends captured network messages to a remote server using a TCP client with worker pools.
• Timing-Preserving Replayers - Emits recorded network traffic while respecting the original timing and delays between requests.
• TCP Proxies - Provides a utility for intercepting, inspecting, and recording raw TCP traffic streams.
• TCP Session Management - Duplicates raw TCP sessions to maintain the exact state and sequence of network connections.
• Traffic Filters - Excludes specific requests or responses from replay based on criteria like HTTP methods or headers.
• Traffic Routing Tools - Sends and receives captured network traffic from Kafka topics using JSON format with SASL and TLS encryption.
• TCP and UDP Forwarders - Sends raw network payloads to remote addresses using secure or insecure TCP connections.
• Traffic Distribution - Distributes incoming network traffic equally among multiple output destinations to balance the load.
• Data Masking - Removes or replaces personally identifiable information in captured HTTP requests to protect privacy during testing.
• Rate Limiting - Caps the rate of processed requests using fixed counts or percentages to protect target systems.
• Traffic Modification Plugins - Directs network data between input sources and output destinations via a pluggable architecture for flexible steering.
• Multi-Destination Forwarding - Replicates and sends captured network traffic to multiple independent HTTP endpoints simultaneously.
• Traffic Analysis - Captures and stores HTTP payloads in Elasticsearch or S3 for long term archival and behavioral analysis.
• Response Validation - Validates that replayed traffic output matches original production responses by mapping related requests and responses.
• Network and Security - Tool for capturing and replaying live HTTP traffic.
