A modular Rust library for building production-ready distributed services with built-in observability and security.
Foundations is a modular Rust library designed to help scale programs for distributed, production-grade systems. It provides built-in components for logging, tracing, metrics, security, and configuration, allowing engineers to concentrate on core business logic rather than operational setup.
Rust developers building distributed services or production systems who need robust observability, security, and configuration management without implementing these concerns from scratch.
Developers choose Foundations for its comprehensive, production-focused feature set that reduces boilerplate and ensures services are observable, secure, and configurable by default, leveraging Rust's performance and safety.

Combines structured logging, distributed tracing, and metrics collection in one package, reducing the need to integrate multiple separate libraries.
Integrates seccomp-based syscall filtering out of the box, enhancing application security without requiring custom implementation.
Provides documented configuration with validation and a CLI helper for loading, simplifying deployment and reducing boilerplate code.
Direct support for jemalloc allows for advanced memory allocation analysis, which is crucial for performance tuning in production services.
Tied exclusively to the Rust ecosystem, making it unsuitable for teams using other languages or mixed-technology stacks.
Developed by Cloudflare, it may include optimizations or defaults tailored to their infrastructure, requiring extra configuration for other environments.
Memory profiling relies on jemalloc, which can add complexity or conflicts if other allocators are preferred or already in use.
