ScaleDojo is an interactive, hands-on learning platform for system design, software architecture, API design, database schema design, and generative AI pipelines. Learn by building real distributed architectures, modeling schemas, and designing production-ready APIs with instant AI feedback.
Deep dives, tutorials, and practical guides to level up your architecture skills.
A complete guide on Low-Level Design: OOPs, UML and Object Modeling, SOLID Principals, Design Patterns, Concurrency. Explained with diagrams, examples and visuals.
A practical look at cache invalidation (TTL, LRU, write-through/write-behind) and where to place caches (browser, CDN, Redis), with the trade-offs that actually matter in production.
Reading about system design won't get you hired interviews test what you can build, not what you recognize. We tested the top 6 system design platforms in 2026 (including ByteByteGo, DesignGurus, and ScaleDojo) across high-level architecture, low-level schema design, API contracts, and the critical new frontier of GenAI pipelines. Discover which platform transitions you from a passive reader to an active architect who can confidently design production-grade systems under pressure.
Modern systems do not pick one protocol and stick with it. API gateways manage the interface, BFF adapts it per client, and the AI era is rewriting what API design even means.
Async APIs need contracts too. AsyncAPI brought documentation to event-driven systems. CloudEvents standardized the envelope. The outbox pattern solved the hardest reliability problem.
Not all APIs are request-response. The async world has its own protocols and patterns - and they solve problems that HTTP never could.
REST and JSON work great for human-readable APIs. When you need to serialize a billion requests per day with microsecond latency, you need a different approach.
Apollo built the platform that made GraphQL practical. Subscriptions added real-time. Federation let multiple teams own different parts of the same graph.
Facebook's iOS app was slow in 2012 because REST made mobile apps fetch too much data. The team built to fix it invented GraphQL. Three years later, they gave it to everyone.
Stripe's API became the benchmark every other API is measured against. Swagger gave the industry a contract format. OAuth 2.0 made auth simpler and more flexible.
OAuth solved the fundamental security problem of APIs. Webhooks inverted the call model. Twilio proved that a company could be built entirely on an API product.
JSON made REST accessible to every developer. Twitter standardized what a public REST API looked like. The Richardson Maturity Model gave everyone a common vocabulary for API quality.
