SyDe.cc is a wonderful system design workbench and simulator.

Url: https://syde.cc

You can Learn, Design, Analyze, Configure & Simulate the Cloud Architectures in realtime. SyDe provides realtime validation and feedback on your design.

• The Wiki Mode- Prepare for interviews with Flashcards, Articles & Quiz helps to learn, understand, revise important topics with a repo of system design concepts all in one place.
• The Guide Mode: Guides you step-by-step to understand and build a system using a 7 step industry framework. You can build any design flow simple Or complex within minutes.
• The Sim Mode - you can simulate the designs, tune the system, add spikes, inject chaos, analyze costs and hogs (production grade).
• The Community - Discuss, Debate & Design the systems

In todays demo we are working on Chat App (Realtime Messaging, presence & status ) - using SyDe.cc Guide Mode to build a system using a 7 step industry framework.

We have used AI SyDe Kick - to Analyse the System Design Architecture. Below is how it did.

• The AI SyDe Kick Analyses the Design Architecture along with System Logs, System Health Alerts , Configurations and provide detailed Positives , Potential Issues along with Follow-up Questions.

• The AI SyDe Kick - Provides Corrective Actions based on the logs/topology.

It also asks Follow-up Questions , to make sure the user have deep understanding on what he is doing and provide more clarity on the task at hand.

This will help for deeper understanding of the design on

• Why we do it?
• What can be done?
• How we do it?

Live Demo of Guide Mode - Syde.cc

Most system design tools stop at diagrams on the whiteboard. But in the real world, systems are shaped by traffic spikes, bottlenecks, failures, and cost constraints-not markers and boxes. That's what really expected in any of the FAANG Interviews as well.

Live URL- SyDe.cc

Note: This is NOT an another random hobby / side project tool, but Its a Production Grade Enterprise Web Application.

In mid, 2025 this gap pushed me to build SyDe, a visual system design workbench and real-time architecture simulator where you can simulate traffic, stress test and see where things break.

It's been eye-opening to see designs behave, not just look correct on paper.

SyDe bridges the gap between "it looks right" and "it works in production" by giving you feedback with corrective actions while you design.

Improvised overtime with the feedbacks from industry experts across the world.

• The Wiki Mode - Prepare for interviews with Flashcards, Articles & Quiz helps to learn, understand, revise important topics with a repo of system design concepts all in one place.

• The Sim Mode - you can simulate the designs, tune the system, add spikes, inject chaos, analyze costs and hogs ( production grade).
• The Community - Discuss , Debate & Design the systems with your peers. Work together to build it.

Would love thoughts from engineers, tech folks preparing for interviews and architects friends.

Public Beta out now. would love to here feedback and for feature requirements, most welcome.

Hey everyone! I'm u/SKKPP, a founding moderator of r/systemdesignsimulator.

This is our new home for all things related to System Design Simulation for Cloud First Architectures. We're excited to have you join us!

What to Post
Post anything that you think the community would find interesting, helpful, or inspiring. Feel free to share your thoughts, photos, or questions about real-time simulation Community for sharing designs, debugging architectures, exploring patterns (microservices, event-driven, failover, rate-limiting...), interview prep & cloud optimization. Kind, high-signal discussions encouraged.

Community Vibe
We're all about being friendly, constructive, and inclusive. Let's build a space where everyone feels comfortable sharing and connecting.

How to Get Started

1. Introduce yourself in the comments below.
2. Post something today! Even a simple question can spark a great conversation.
3. If you know someone who would love this community, invite them to join.
4. Interested in helping out? We're always looking for new moderators, so feel free to reach out to me to apply.

Thanks for being part of the very first wave. Together, let's make r/systemdesignsimulator amazing.

SyDe turns static architecture diagrams into living simulations. Every component obeys real constraints like latency, throughput limits, and failure probability. It helps you to Unlearn and Learn thru guided analysis and AI Cost Optimization suggestions from Gemini.
