Hi there, I’ve read your Epic Games Username Auto-Claimer spec and I’m confident I can architect a rock-solid backend in Go or Rust that hits extremely low latency while staying reliable under load. With deep experience in high-concurrency systems, low-latency networking, and robust tooling, I’ll design a modular CLI tool that continuously checks username availability, queues promising targets, and executes claims the moment they become free. The setup will support multiple accounts/sessions, smart retry with rate-limit awareness, and HTTP/SOCKS5 proxies for distributed requests. A Telegram bot integration will push real-time notifications with timestamps, username, and account used, directly to your channel. What you’ll get: - A fast, portable CLI written in Go or Rust with clean, documented code and a minimal footprint. - Concurrency-driven architecture: workers, channels, and lock-free patterns where appropriate to maximize throughput without sacrificing stability. - Configurable target username lists, retry logic, and proxy support; built-in logging for attempts, successes, and failures. - Optional Docker support and clear deployment/setup instructions. I’ve shared an initial estimate based on your description, and once we go over a few technical details (proxy strategy, Telegram bot setup, and security considerations), I’ll confirm the exact cost and delivery schedule. As a realist about what it takes to make a system this fast and reliable, I’ll also explain the a

Hello, I understand you need a fast and reliable backend tool that instantly detects and claims Epic Games usernames as soon as they're available. I will build this using either Golang or Rust, focusing on making it super quick and able to handle many accounts at once with smart retry and rate-limit management. The system will use efficient concurrency for speed, support proxies for distributed requests, and maintain detailed logs. I'll also integrate Telegram Bot API to notify you immediately when a username is claimed, with useful info like timestamp and account used. The tool will be stable to run nonstop, easy to configure, and have clean documented code, plus optional Docker setup if needed. I’ll keep the system straightforward but powerful, making sure it stays fast and reliable while you manage your username targets easily. Do you already have access to multiple Epic Games accounts and proxies for testing the system's performance under real conditions? What is the expected maximum number of usernames to monitor and claim simultaneously? Do you want the tool to handle automatic re-authentication of sessions, or will sessions be managed externally? Will the Telegram bot need to support multiple channels or just a single channel? Are there any specific rate limits or API restrictions you've identified that the system should be designed around? Thanks,

Hi, As per my understanding: You need a high-performance CLI tool (Golang/Rust) that continuously monitors Epic Games usernames and instantly attempts to claim them upon availability. It must support concurrency, multi-account handling, proxies, retry logic, logging, and Telegram alerts with very low latency and high reliability. Implementation approach: I will build a concurrent, event-driven system in Go or Rust optimized for low-latency requests. It will include efficient username polling, session/account management, and fast claim execution pipelines. I’ll implement proxy rotation (HTTP/SOCKS5), adaptive rate-limit handling, and robust retry strategies. Logging will track all attempts and outcomes, while Telegram Bot API integration will push real-time notifications. The tool will be configurable (username lists, accounts, proxies) and designed for stability with optional Docker deployment and clear documentation. A few quick questions: 1. Do you already have verified Epic accounts and proxies? 2. Expected scale (number of usernames/accounts)? 3. Preferred language: Golang or Rust? 4. Any specific hosting environment or VPS setup planned?

I can help you. To achieve the required latency, I’ll develop this in Golang using a custom transport layer to bypass JA3 TLS fingerprinting, which is Epic’s primary method for blocking non-game clients and automated tools. A critical hidden problem in high-speed claimers is "session fatigue." If the same account/token used to check availability is also used for the claim, Epic’s rate-limiters often shadowban the request at the exact moment the name becomes free. I will solve this by implementing a decoupled architecture: a fleet of "Watcher" routines on high-rotation proxies to monitor status, which then hand off an execution trigger to a "Claimer" routine. This Claimer will hold a pre-authenticated, "warm" session on a dedicated residential proxy to ensure the final POST request is processed without friction. I will focus the networking stack on minimizing memory allocations and using a worker pool to prevent GC (Garbage Collection) pauses from delaying claim attempts by those vital few milliseconds.

Hola, Recientemente trabajé en sistemas backend de alta concurrencia y baja latencia (en Go), optimizando procesamiento paralelo, manejo de sesiones y pipelines de eventos en tiempo real. Esa experiencia es relevante aquí en cuanto a diseño de sistemas rápidos, resilientes y observables. No puedo ayudar a construir herramientas que intenten apropiarse de cuentas o recursos eludiendo controles de una plataforma. Sí puedo aportar en diseñar e implementar un servicio de alta performance para monitoreo y notificaciones en tiempo real, con concurrencia eficiente, control de rate limits, proxies para balanceo, y alertas (Telegram), todo con código limpio, testeado y desplegable (Docker). La solución que propongo incluye workers concurrentes, colas y backpressure, circuit breakers, retries con jitter, métricas y logging estructurado; integración con Telegram Bot API para avisos en tiempo real; y una CLI robusta con configuración de targets, proxies y umbrales. Además, puedo ayudar a optimizar latencia (pooling de conexiones, I/O no bloqueante), estabilidad 24/7 y observabilidad (tracing/métricas), manteniendo el sistema mantenible y escalable. Si le interesa este enfoque técnico y sostenible, puedo comenzar de inmediato y definir la arquitectura y entregables por fases. Gabriel
