The free, open companion to the Grokking the System Design Interview course, published as a GitHub repository. It teaches a pattern-first approach: learn building blocks such as caching, sharding, replication and queues well enough that any design question becomes a matter of combining them. It includes a seven-step interview framework, 30 patterns, 59 question walkthroughs, company guides, cheat sheets and study roadmaps, all readable in the browser without an account.

An interactive practice tool for system design questions: you work through a real-world design step by step on a whiteboard and receive AI-powered feedback on your answer. Your practice sessions are saved with their status, so you can return to them and review results. It fills the gap most preparation leaves open, which is actually producing designs under realistic conditions rather than only reading worked answers.

A course on object oriented and low level design interviews. It teaches a repeatable method (requirements, actors and use cases, class diagram, code) with UML basics and SOLID, then applies it to 22 case studies such as a parking lot, elevator, ATM, chess, movie booking, Splitwise and an in-memory cache, with runnable code in Python, Java and C++. It suits candidates facing a dedicated OOD or LLD round.

• System design

A free GitHub link hub by Arpit Adlakha covering data structures and algorithms, low-level design and high-level system design. It gathers pattern write-ups for dynamic programming, sliding window and binary search, video lectures, practice sites, low-level design questions with solutions, system design reading and database design articles. It is a directory rather than original teaching material, last updated in December 2024.

• System design

An Anthropic article from December 2024 that separates workflows (models run through fixed code paths) from agents (models directing their own steps) and describes the common patterns for each. It is for engineers designing any system with more than one model call. Its main lesson is to start with the simplest pattern that works and add autonomy only when the problem needs it.
