Thanks for checking out bauplan (which also supports BYOC, so I guess it is indeed hostable by you in a sense!).

We've done quite a lot of open source in our life, at Bauplan (you can check our github), and before (you can check me ;-)), so the comment seems unfair!

We understand the importance of being clear on how the platform works, and for that we have a long series of blog posts and, if you're so inclined, quite a few peer-reviewed papers in top conferences, ranging from low-level memory optimizations (https://arxiv.org/abs/2504.06151), columnar caching (https://arxiv.org/abs/2411.08203), novel FaaS runtimes (https://arxiv.org/pdf/2410.17465), pipeline reproducibility (https://arxiv.org/pdf/2404.13682) and more.

We are also always happy to chat about our tech choices if you're interested.
