I love what is trying to be done here. Some feedback to improve would be to cut out a lot of the noise with the "Take tour". There are too many boxes and things changing on the screen to get a sense of what is happening. Also make it interactive rather than automatically switch onto the next subject. Being a passive observer to so much information trying to be conveyed is very confusing.

I really do like these kinds of approaches to showing the inner workings of different kinds of tech, so think this is on the good path to being a very useful tool, but needs some focus rather than more data/graphs/info boxes.

I imagined as soon I saw the initial visual that I would somehow be able to enter a query and it would walk me through the flow through the entire system starting from input parsing to all the way to delivering output and perhaps along the way understand some of the autonomous processes that happen in parallel that aren't query specific but run constantly.

What others are saying - fantastic attempt, but don't know where to start or where to end.

Considering that it has been vibe-coded with not even 48 hours passed: Is this truthful and accurate at all? Or will it lead to false conclusions and anti-knowledge?

Understanding how scheduling works inside a database used to require numerous architecture diagrams to explain. I was amazed when I saw PGSimCity — it presents such a complex technical implementation process in such an engaging way. Since it's already open‑source, I think the same idea can be reused in other domains, such as cloud computing, Kubernetes, and so on.

I can't believe "Rendering The First Frame..." is not "Reticulating Splines..." :)

Cool UI.

The logo shape of the platform is a very niche touch, kudos

Bravo! I have worked in observability for years and I have a deep desire for new visualizations technics inspired by video games. It would be great in XR as well.

Virtually it's so amazing to see. The layers are clearly separated and it does give a sense of the connections being accepted and processed in the central part.

The operation intricacies are a bit difficult to understand because the core looks a bit clogged up. Nonetheless, great work!

I love this, let's do all of Data Intensive Application SimCity!

I don't know what I am looking at but it is fabulous.

It's a cool and very educative way to learn. But I wish there's like a live query thing going on so that it'd be easy to understand. I am viewing on the 27" 4K screen and it's perfect for it, like others said, I don't feel there's too much boxes and info at the same time. Although the site is going blank sometimes if I zoom in a bit too much. Really cool nonetheless.

This is really cool, I like having visualization to hold on my head!

Also (assuming this is LLM-generated, apologies if it’s not) seems like the future of learning/self-teaching… gonna try and generate similar things for stuff I’m learning

Besides the sadly obvious vibe-coding, just note that SimCity is still an active trademark from EA, so might be good to rename it.

Anyone else getting Reboot vibes?

I have a pretty good working knowledge of the internals of Postgres, but this just confused me. I think it's too busy to understand. At the very least, it would be cool if there were a "slow down" button.

Visualizing MVCC and transaction visibility would make this even more valuable as a learning tool.

It surely is impressive,but it’s just that - components of db service as buildings/machine. What it needs is narrative, purpose, with main actors clearly defined - client and data. demonstrating what is involved in the chain when data’s written and requested.

Really great work! I've always wanted to build a CPU simulator(Full PC simulator) in this style. I still haven't fully figured out my own approach, but this will definitely be an inspiration for me. Thanks for making and sharing it.

Great work! When zooming out a bit, I'm somewhat sure that the 'blinking'/glitching is due to z-fighting. Just something you may want to look into (ie move 3d surfaces so that they're not at the exact same z)

This is very cool, just some UX tips to make it more legible:

1. remove ~50% of the UI since it covers too much of a laptop screen

2. improve the camera controls so its easier to pan and zoom.

Wow, cool projects are so back again

Wow. Can’t wait to explore the architecture

So much stuff to see but looks very cool!

Amazing, great work. Keep polishing this up!

Someone should make a movie called “Postgres” which is about people living within a Postgres city, in the style of Se7en.

“Every city has secrets. Ours have indexes.”

I like the education tools being developed using coding agents, but there should be some review in the process.

Good luck continuing it, hope you generated something that can be iterated on.

thats cool. n1. spent 15min looking on it rn

This is amazing!

Love this

maybe try adding tts to the tour? Lol

i understood all that.

3.86B tokens to build a visual simulator of a database that runs on a fraction of that compute. we're using the expensive brain to draw pictures of the cheap brain.
