Introduction

Molock is a production-ready mock server designed for high-throughput environments, CI/CD pipelines, and stress testing. Built in Rust with Actix-web, it provides configurable and observable mock endpoints with native OpenTelemetry integration.

🏛️ Core Pillars

Molock is built on three foundational pillars:

1. 🚀 Extreme Performance: Leveraging Rust and Actix-web for zero-allocation hot paths and maximum throughput (>10k req/s).
2. 🔭 Native Observability: OpenTelemetry is a first-class citizen, providing out-of-the-box traces, metrics, and logs.
3. 🛡️ Rigorous Quality: Developed using strict Test-Driven Development (TDD) with >80% line/branch coverage and SLSA Level 2 supply chain security.

🏗️ Architecture

Molock follows a modular architecture designed for speed and extensibility:
