NexusSend operates on a highly distributed, custom-built routing architecture.
All incoming REST API requests and OAuth consent flows are handled by our horizontally scaled Node.js clusters. These gateways manage JWT validation and proxy assignment.
To achieve high-concurrency without memory bottlenecks, our actual payload transmission is handled by bare-metal C++ worker nodes running advanced threading protocols.
If standard API routes are throttled, our engine seamlessly fails over to automated Playwright instances to process payloads via simulated browser sessions.
