Zero-Copy API Gateway: The Future of High-Performance API Forwarding

Eric

The API Forwarding Revolution

Traditional API gateways introduce latency and overhead by:

  • Copying data multiple times
  • Buffering entire requests/responses
  • Adding unnecessary processing layers

Our solution changes everything with true zero-copy forwarding.

Perfect Protocol Preservation

How We Maintain 100% Compatibility

Client Request → [Our Gateway] → Upstream Service
    │                      │
    └─ Original Protocol ──┘

We support:

  • Full protocol transparency: SSE, REST
  • Native streaming: No chunking or buffering artifacts
  • Binary perfect: Bit-for-bit identical output

Smart Connection Handling

# Pseudocode: Intelligent connection management
def forward_request(request):
    connection = get_optimized_connection(request)
    return connection.stream(request)  # Zero-copy

Performance That Speaks for Itself

Benchmark Results
