Is there a way to create stack references across projects when not using the pulumi service? Say I have a project in 
<s3://foo/project1|s3://foo/project1>
and an other in 
<s3://foo/project2|s3://foo/project2>

yep, just references the name of the project: 
const stackRef = new pulumi.StackReference("vpc.prod")
It's recommended to name your projects and stacks with prefixes like you can see here

Doesn't that work only when the two projects have the same backend URL? So you'd need both to have 
<s3://foo/allprojects>
, and then you can refer to "vpc.prod" in there, from the prod stack of the app project..

I don't get how this works. If I am in project1 and want to reference project2 (stack dev) I just have to use "project2.dev"? How does pulumi know its in 
<s3://foo/project2/.pulumi/stacks/|s3://foo/project2/.pulumi/stacks/>

Iirc, you can't. You need to have both projects in the same key in the same bucket. And that's what you need the stack name to include the project name: so that they get different keys in the one big json file.

Oh damned..
Are there references to filenames and buckets in the files or can I get away by just moving them?

Can't answer that. You can definitely create a new stack in the right place, then export the old one and import it to the new place.

Well then, let the nightmare begin, thanks a lot! 😭

Please note, my responses have been caveated with "iirc".. this is how it was over a year ago, when I used S3 buckets. Lee may well be right, things may have been improved...
Worth double-checking.

Where can I double check anyway? The doc just does talk about that, and most github issues are 2y old anyway, this slack is the only source of info AFAIK

Just try a stackreference like Lee suggested 🙂

@refined-appointment-5884 Check this project, it's quite complex and has many projects and directories https://github.com/mitodl/ol-infrastructure/tree/main/src/ol_infrastructure

it's not improved I'm afraid, I didn't realise there were things being stored under different paths. You're correct in saying that won't work @little-cartoon-10569

It creates weird things to have all projects use the same s3 key
Like 
stack ls
now lists stacks from other projects
I named my stacks project1.prod and project2.prod
And when doing stack ls for project1 is see both project1.prod and project2.prod
Also export/import will not work as stack names are different >_<
Need to stack rename first

FWIW, it looks like this is going to get a lot better soon: https://github.com/pulumi/pulumi/issues/4605
