Show HN: Tugboat – A fully working website for every pull request

Biased nerd here: I work for Lullabot and have been adjacent to a number of projects that used Tugboat for client QA and approval over the past year or two. While I can't speak to the implementation details, I can definitely say that the emphasis on automatically spinning up per-pull-request/per-feature demo instances of fairly complex sites and linking them from the PR tickets has made review and approval by nontech stakeholders way smoother.

I'd be interested in knowing if there are any other CI or CI-adjacent tools taking that approach, especially with non-LAMP hosting stacks?
