Design scalable systems faster. Describe your system design in plain English and get professional high level design diagrams, sequence flows, and ER models generated instantly. Perfect for system design interviews and documentation.
System design is the process of defining the architecture, components, data models, and interfaces of a software system. It encompasses both high level design (HLD) — the overall system architecture with services, databases, and APIs — and low level design (LLD) — detailed class diagrams, database schemas, and algorithm choices.
System design is critical for building scalable systems that handle millions of users. It covers topics like load balancing, database sharding, caching strategies, message queues, and microservice communication patterns. Companies like Google, Amazon, Meta, and Netflix evaluate system design skills in technical interviews.
Cybewave Studio's system design tool converts your descriptions into structured system design diagrams — architecture overviews, sequence flows, ER models, and component views — using Mermaid and PlantUML notation. Whether you're preparing for a system design interview or documenting production systems, the AI handles diagram creation so you can focus on architecture decisions.
Describe once, get a complete set of diagrams covering both high level and low level design.
High-level view of services, databases, queues, and external integrations. Perfect for system design interview whiteboard sessions.
Request flows between actors, services, and data stores. Show authentication flows, API call chains, and async event handling.
Entity relationships with fields, types, PKs, and foreign keys. Model your database schema visually with proper cardinality.
System boundaries, deployment topology, and dependencies. Visualize C4 containers and bounded contexts.
Practice these classic system design problems — describe each system and get instant diagrams.
Design a URL shortening service like Bitly with hashing, redirection, and analytics.
Design WhatsApp/Slack with real-time delivery, message storage, and presence.
Design a Facebook/Twitter feed with fan-out, ranking, and pagination.
Design a distributed caching system like Redis with sharding, replication, and eviction.
Design Netflix/YouTube with video processing, CDN, and adaptive streaming.
Design Uber/Lyft with real-time matching, geospatial indexing, and ETA prediction.
Whether you're preparing for a system design interview or documenting production systems.
Practice system design by describing systems and getting instant architecture diagrams with AI feedback. Perfect preparation for FAANG, Google, Amazon, Meta, and startup interviews.
Generate up-to-date system design diagrams from descriptions. Keep docs in sync with your actual architecture as systems evolve.
Visualize proposed changes before implementation. Share interactive diagrams with stakeholders, engineering managers, and leadership teams.
Create clear system overviews that help new team members understand the codebase, service topology, and data flows quickly.
Map out failure paths, service dependencies, and blast radius with sequence and component diagrams. Identify single points of failure.
Support your technical proposals with professional system design diagrams generated from your high-level design description.
Building scalable system design requires understanding patterns that handle increasing load. Cybewave's AI understands and diagrams these patterns automatically when you describe your requirements:
Load balancers distributing traffic across service replicas with auto-scaling groups.
Partitioning data across multiple database instances by key ranges or consistent hashing.
Redis/Memcached for hot data, CDN for static assets, application-level memoization.
Kafka, RabbitMQ, or SQS for decoupling services and handling spikes asynchronously.
Separate read and write models with event logs for audit trails and replay.
Istio/Envoy sidecar proxies for service discovery, circuit breaking, and observability.
Purpose-built for software engineers, not generic whiteboarding.
