Hey Product Hunt! 🦖
I made Chenilla Because I wanted a tool to help me understand how systems work. I tried to learn through books and guides, but they are too heavy and still did not give me the consciousness to see and understand the system visually.
So I built a flight simulator for it. You design a system visually, hit play, and watch traffic flow through it in real time. When your database slows down or your queue fills up, you see it happen. You fix it, play it again, and develop the kind of insight you can get from seeing things break.
What you can do:
Drag and drop 7 universal building blocks.
Wires components together and defines simulation metrics and behaviors.
12 programmable modes: queue, retry, filter, batch, rate limit, circuit breaker, and more
Press play to view and watch real packet traffic in your architecture.
See bottlenecks, drops, and queue pressures as they happen.
Clear the timeline to inspect any moment frame by frame.
Describe a system in plain English or paste code or text (framework, papers, etc.), Chinilla AI maps it to the canvas.
Eliminate groups, enter subsystems, explore at any level.
Find vulnerabilities with stability analysis, Monte Carlo with SLO targets, and stress testing.
Export to PNG, GIF, SVG, Mermaid, Python code, or Markdown spec
Publish a live interactive link with MD Embed to papers or repos.
16 templates to learn by doing (ML pipeline, coffee shop, chat app, rate limiter, and more)
It’s free to use in your browser. The demo takes about 60 seconds and does not require an account: chinilla.com/demo
With a free account you get 5 cloud projects, full simulation, all export formats. No credit card.
This project took a lot of time. I would love to hear from you all what you think!
What’s next:
Team collaboration (shared canvases, real-time cursors)
Duolingo-style interactive lessons are fully developed that teach system design step-by-step.
Strict simulated fix loop (inline suggestions when things break)
Integration (import from Terraform, CloudFormation, Docker Compose)
Better UX polish based on your feedback (seriously, tell me what’s bad)
Launch Special: Launch 50 for 50% off Pro Monthly (Until April 30)!!
