App Observatory is currently in active development. Based on the Trello cards, I think the private beta should be available by the end of March 2022. Since the private beta is incoming, I figured a new website with more content would be helpful in keeping everyone informed.
The site is built with Jigsaw by Tighten and hosted on Netlify. This process has been incredibly fast and easy to get a site up and going. I highly recommend it for any developers familiar with Laravel that wants to quickly set up a static site.
