Generator für System-Design-Aufgaben
A system design prompt generator produces structured practice questions for system design interviews and self-study. Pick a classic system to design — a URL shortener, a news feed, a chat app, and more — and it returns the prompt plus the framework strong candidates follow: clarify requirements and scale, define the API, design the data model, sketch the high-level architecture, address scaling, and discuss trade-offs. Engineers use it to rehearse interviews, study groups to run mock sessions, and self-learners to practise architectural thinking. System design rewards a clear process more than a memorised answer, and walking the same structure each time builds the habit of covering requirements and trade-offs. Use the framework to talk through the design out loud, stating assumptions and justifying each decision — interviewers care far more about your reasoning than a single "correct" architecture.

FAQ
how should i use the framework
Talk or write through each step in order: clarify requirements and scale first, then API, data model, high-level design, scaling, and trade-offs. The discipline of covering them all is what interviewers look for.
is there one correct answer
No. System design is about reasoning and trade-offs, not a single right architecture. Stating assumptions and justifying your decisions matters far more than arriving at a specific diagram.
why start with requirements
Scoping the problem — scale, features, constraints — shapes every later decision. Candidates who skip straight to a solution often design for the wrong scale, so clarifying requirements first is the strongest habit to build.
How should I use a system design prompt?
Treat it like a real interview: start by clarifying requirements and scale, sketch the high-level architecture, then dive into data model, APIs, bottlenecks, and trade-offs. Talk through your reasoning out loud. The prompt gives the scenario; practicing the structured approach — not memorizing one answer — is what builds the skill.
Is there one correct answer to a system design prompt?
No — system design is about trade-offs, so there are many valid designs depending on the constraints you assume. Interviewers assess how you reason: do you clarify requirements, justify choices, and acknowledge limitations? Use the prompt to practice defending a coherent design, not to find a single "right" diagram.
