Enterprise-Grade Observability Platform for Modern Cloud Infrastructure

100% OpenTelemetry Compliant • Built with DDD/CQRS • Production-Ready

TelemetryFlow is an enterprise-grade observability platform that provides comprehensive monitoring, logging, and tracing capabilities for modern cloud-native applications. Built from the ground up with Domain-Driven Design (DDD) and CQRS patterns, it delivers industrial-strength reliability with developer-friendly APIs.

• 100% OTLP Compliance - Full support for metrics, logs, and traces
• Native Protocol Support - OTLP/HTTP and OTLP/gRPC
• Zero Vendor Lock-in - Standard OpenTelemetry SDKs and collectors
• Seamless Integration - Works with existing OTEL instrumentation

• Domain-Driven Design - 15+ business modules + 10+ shared modules with clear boundaries
• CQRS Implementation - 40+ command/query handlers for optimal performance
• Event-Driven - NATS + BullMQ hybrid messaging for real-time events
• Multi-Tenancy - Hierarchical isolation (Region → Organization → Workspace → Tenant)
• Modular Design - LEGO-pattern modules for easy extension

• 5-Tier RBAC System - Granular role-based access control
• AWS-Style API Keys - Dual-key authentication (tfk-/tfs-)
• Argon2id Hashing - OWASP-recommended cryptographic security
• MFA Support - TOTP with backup codes
• SSO Ready - Google, GitHub, Azure AD, SAML, OIDC
• Complete Audit Trail - Every action logged to ClickHouse

• ClickHouse Backend - Columnar storage for 100x query performance
• Horizontal Scaling - Stateless authentication and distributed caching
