Everything you need to design and test systems
Why Chinilla?
Works for any domain
7 simple building blocks that map to anything. Design a restaurant, a backend, a hospital, or a factory. No jargon required.
Living systems, not static diagrams
Watch behavior, not just structure. Run data through your design and find problems before they find you.
AI that works with you
Describe what you want, review changes as a visual diff, then accept or reject. Not a black box.
Your data stays yours
Secure, private, and stored with your account. No tracking, no data selling.
Learn system design by building
Start from templates
Load real-world architectures like a URL shortener, chat app, or payment system. Explore how they work before building your own.
Simulate and get feedback
Run your design step by step. See where queues overflow, where latency spikes, and where single points of failure hide.
Let Chinilla AI guide you
Ask why a design fails, get suggestions to fix it, and learn the patterns that show up in every system design interview.
