## What it is
A curated collection of visual guides explaining complex system design concepts using diagrams and simple terms. It is primarily aimed at developers preparing for system design interviews or wanting to understand how large-scale systems work.

## Use cases
- prepare for a system design interview
- learn how load balancers and API gateways work
- understand REST, gRPC, GraphQL, and WebSocket concepts visually
- study cloud and distributed systems fundamentals
- review common software architecture patterns before an interview
- learn how databases, caching, and CI/CD pipelines work

## When to choose
- you are preparing for system design or coding interviews
- you prefer visual, diagram-based explanations of engineering topics
- you want a broad survey of cloud, API, and architecture concepts in one place

## When to avoid
- you need runnable code or a working tool rather than educational material
- you need deep, rigorous treatment of a single specialized topic
- you require a permissively licensed resource you can redistribute

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, documentation
- domain: developer-tools, cloud-computing, web-development, tutorials, awesome-lists
- platform: -
- tags: system-design, interview-preparation, visual-guides, software-architecture, educational, web-server
