A full-featured 2D + 3D CAD application built in Rust with GPU-accelerated rendering. Native DWG & DXF read and write, paper space, ACIS solids, dimensions, layouts. An open source community project by Hakan Seven, recognized and promoted by the OpenAEC Foundation.
Why is a post about a CAD program being downvoted so much?
Probably because it’s not a self hosting project, and it also appears to be almost entirely vibe coded. When asked about the former, OP also claimed they didn’t read or care about the community rules, though it does appear they’ve since added the ai tag.
Oh yeah… yeah, it doesn’t seem like it’s client/server or anything. It’s just a CAD program?
Doesn’t fit this at all.
I dunno if it fits the “vibe coded” label though, as it appears to work well. I tend to apply that to quick hacks, or to projects where the devs clearly have no idea what they’re doing (and end up with something really bloated and janky, yet hyped a ton).
To quote from another thread about this program:
Claude directly has over 1100000 lines of direct code contribution. It has pretty much the same amount of code committed directly as the creator has.
His entire coding history before Claude consisted of changing readmes or searching and replacing project name text or modifying a dead link to his own link.
Suddenly in 4 months, without ever producing actual code before, he becomes a very competent coder enough to tackle mCAD, a notoriously difficult coding task that takes many many years with teams to make meaningful progress on?
That is vibe coding.
And his co-contributer “gianlucafiore” is exactly the same story. Has literally only made issues until LLM coding got released and then late 2025 (December) switched to making commits that he badly copied from an LLM such that some of the commits are literally one full line (as direct in-file working of the LLM wasn’t as accessible then)
That is vibe coding.
So the top 3 contributes are
- An LLM
- Someone that only has committed any code via an LLM
- Someone who has only made issues before beginning with an LLM and submits clearly generated code
There is likely no human-made code in the entire project besides changing a couple links.

If a program written almost entirely by Claude under somebody who has not previously demonstrated any actual competency in this domain isn’t vibe coding, I really don’t know what is.
Yeah, in that case it’s sus. I’d be scared to look at the codebase.
Does it actually work, though?
If I read the page correctly, the project was launched in the last couple months. I’m not seeing many reviews or demonstrations online yet, but I also didn’t look very hard.
I personally don’t have any interest in mostly vibe-coded projects and won’t be trying it.
That said, I’d be curious to hear from anyone who has tried it. It’s certainly welcome to see open-source competitors popping up for AEC software.
Yeah.
Don’t get me wrong, I don’t want to touch projects vibe coded to this level, going solely on past experience with them.
But I am scientifically curious about its functionality.
or care about the community rules
Where did he say this? He said he didn’t read the rules. Also, when I explained the rules (tho in error), where to find them, and decode them, instead of just piling on like everyone else, when I came back, OP had added the tag. That doesn’t seem like he didn’t ‘care about the community rules’. OP doesn’t seem to be fluent in English, and stated such. Yes, the rules are posted and are there for proper formatting of threads. So imagine yourself visiting a selfhosting site that’s written in Mandarin. ffs!
Elsewhere in this thread, I can’t seem to get the link on my phone:
Rulues was not readed, but i do know most people do not want AI code. So i did know what the issue you point just from your comment
I will not hold post about great FOSS project becuse of AI code.
Thanks.
They admitted that they chose not to read the community rules and appear to have assumed that they were not allowed to post about AI projects, yet chose to post anyway.
Also, translation tools are widely available on the Internet to the extent that they’re built into most browsers at this point. While they’re obviously not as good as actually being fluent, they work fine for getting the point across. I’ve used them to read non-English sites with success, even if I maybe missed some of the subtleties of the original text.
It would be far less frustrating if they had at least attempted to read the rules and made a mistake in trying to follow them.
All I’m advocating here is a little common courtesy, you know? Rule 1 if we’re going to talk about rules. Selfhosters are always talking about how we need more people to sever the umbilical cord of Big Data and get into selfhosting, then act like a bunch of elitist snobs. It really is the black eye in the self hosting community.
I get what you’re saying and agree with you that there tends to be an elitist slant within this community, but that courtesy is a two-way street. I don’t think it’s that much to ask that people to put in the bare minimum to respect the spaces they enter without having to be cajoled to do so by others, and in turn, I do my best to respect the communities I visit both online and offline.
I actually rescinded my downvote after they added the tag because they were following the rules at that point, in spite of my misgivings about the project.
Alright man. Rock on wid yo’ bad self.
You as well. For what it’s worth, I do appreciate your points about language and having grace for strangers, and will try to keep them in mind moving forward.
Uncomfortable panties.
Just going to ignore the community rules mate?
Aside of it being slopped is this selfhostable on a server? I can only see app download links (though it seems like they have a browser demo?)
Using AI to code doesn’t make it ‘vibe coding.’ It is currently the best FOSS CAD.

So you read the rules and chose to ignore them…

based on what metric?
I have been using and contributing to FOSS projects for over 10 years, and I was looking for a FOSS alternative to AutoCAD—this is definitely the best 2D CAD. Even with AI and coding skills, you cannot create an app like this. This man did a great job, and releasing it under GPL is awesome.
i mean in comparison to other open cad applications.

I don’t understand what you mean by ‘God’. But no coding skills (or AI) can create a great FOSS CAD project like this. construction engineers need to know about this. we have been searching for it for years
@myusername @selfhosted
I meant exactly that, if you use that shit your proyect, your proyect it’s vibed coded. It could be the best thing ever done, still vibed coded
OP, I get the impression that English isn’t your native tongue, though you’re doing a pretty good job of it. No worries, French isn’t my native tongue either. There are specific rules to posting in this community even if you are promoting someone else’s project/app. They are linked in the side bar. If English is not your native tongue, maybe copy them to Chat GPT and have it translate into your preferred language. The rules are pretty simple to go by.
As far as the pushback against AI, I wouldn’t worry too much about it. A lot here are very adamant about AI. I honestly don’t care too much.
Thank you for your post.
Thanks, I’ll check the rules and see where I can help. And yes, I only use English online, not in real life.
No worries mate!
even if you are promoting someone else’s project/app.
To correct you on this - ifyou are linking someone else’s project/app, it would be entirely impossible to require a disclosure. A tag is a nice-to-have depending on how visible those elements are, but the paid/30 day account age for f/loss would still apply.
I suspect I’ll need to clean up the language some if this is the takeaway.
Me skuzi
ETA: LOL I must have angered an Italian.
'mi scusi' or the formal 'scusi'You guys are hilarious with your downvotes. It’s rather entertaining.No worries, just clarifying, which I’ll need to add into the rules as well somehow…
May your children bear you many grandchildren Don Curbstickle.
That’s a pretty cool concept. I did try uploading a generic 897.88 Kb *.dwg file but everything locked up with this error:
panicked at /rustc/8bab26f4f68e0e26f0bb7960be334d5b520ea452/library/std/src/sys/time/unsupported.rs:35:9: time not implemented on this platformPlease inform him on github. I see he do a fast fix.
Ahhh, you’re not the dev. Sorry, without any other information, I just assumed.
How to build the web version.
