I was unaware of the Hephy Workflow/Deis Labs background, but yes, porter.sh has come up recently and we are aware of this.
For some clarification, Porter was initially started as a remote dev solution (similar to Github Codespaces) as part of the S20 YC batch, which operated in a very different space. When we pivoted to the current PaaS solution, we kept the same company name/domain, but didn't think to check on the name collision after we pivoted.
We're going to address this at some level, whether it be a name change or much more explicit clarification in our Github repo, since we're also unhappy about the name collision. Sorry for any confusion this may have caused.
