Getting Replit's specs

General
1

So. I created a specification dumper for Replit.

Ok, admit it, at one point you probably asked yourself “what does this run on?”.
So I figured that out.

Yea. Looks like a garbage mess except for at the bottom.
So Lets go through it:

Yea… pip and nix are both 16TB.
Not just that, but the AMD EPYC 7B12 is 64 core and goes up to $4,000 USD
And, 64GB of RAM.

You aren’t gonna get that CPU, RAM and storage to your disposal though.
You get: 0.5 vCPUs (enough for 128 people), 1GB of storage, and 512MB of RAM.

I love this but I think we need to note a few things not to confuse anybody.

Mutiple repls are hosted on the same server so depending on the server its being hosted on the avalilve memory may be more or less. It also is maxxed out per repl iirc so you don’t get all of that.

Yes, you are correct that the available memory can be different. There is a total memory list there.
I did say that the memory is not all for you in the bottom.

I am blinder than I thought. You should add that you can boost your repls or subscribe to hack to increase the amount you get

Is this meant to be a showcase?

Showcase is more for showing off your Repls that you are proud of and talking about them with the community (it’s a great place to get feedback for improvements you could make etc), this isn’t really a Repl so I think #general is the best place for it, it’s just an interesting, on-topic, post/article.

I’m sorry. I attempted to post on general.

Nix is so large because it has most dependencies already installed, and when you install them it actually links them without using more storage.

You did, it just seemed like a more showcasy kind of thing, but as @MattDESTROYER said, everything is fine.

I already found the Replit specs here. What I found interesting is that the server runs on Ubuntu Linux even though the packages we add to Repls are from NixOS. I can’t figure out why there is this discrepancy.

I like that you actually took the time to research the CPU. I had no idea that Replit was using a 64-core CPU. I wish I had one of those.

EDIT: I noticed that my Repl’s results are hard to read unless you fullscreen it. I also forgot to mention that you can read the text files for even more information. They are updated every time it’s run. Please note that I made this Repl months ago and the code is not as nice as it would be if I made it now. It still runs though.

Thats actually pretty neat. It took me some time to get CPU info. might as well drop the code:

with open('/proc/cpuinfo', 'r') as f:
   for line in f:
      if line.startswith('model name'):
         specs['Processor'] = line.split(':')[1].strip()
            break

Im gonna end the file here: This goes on until CPU #7.
8 CPU clusters? what magic is going on here?
512 cores. WOW.
Im gonna reply with ore stuff I find.

Alright so a new set of details.

cd’ing into home/runner shows that instead of us being locked out of further access and through some magic us being limited to the correct amount of processing power, they host individual VMs for each user.
Now I know through some magic you are able to get into host from a VM but I don’t think I want to get arrested today.
Another interesting thing is that you are not root.
Although its your own VM, they don’t allow you to get root. Although probably its because there is a way to exit VM using root.

Back to main topic.

Lets check what games are installed on our repl.
cd /
cd usr/games
dir
Awe man. No games.

Lets see whats in terminal.

cd a
less ansi

It is a binary file, but there is some readable text:
“ansi|ansi/pc-term compatible with color”

The total_subvolume_bytes file says 1073741824.
Using bits because im too lazy to divide:
1073741.824 KB
1073.741824 MB
1.073741824 GB
In another post I made a comment about how Replit’s code storage numbers are a little off.
They could have been:
512 MB
1 GB
2.4 GB
This apparently proves 1 GB, which is also what Replit Resources tab says.

couldnt really find anything else

Imagine. Who needs a Pro plan when you have this sort of power for free? That powers is not even close to if we created our programs locally.

15

Except that you don’t get a 64 core CPU for your Repl. You get 0.5 vCPU (virtual CPU) for your Repl. You also are limited in your RAM and storage. Plus the data has to travel across the web. And how do you know that my computer doesn’t have those specs?

16

i even said that in my post

17

You did but strangely OSoft seemed to think that you had that kind of power if you were using Replit.
