Sequel, a database ORM for Ruby: https://github.com/jeremyevans/sequel https://github.com/jeremyevans/sequel The quality of the code is amazing, it's simple to use and even simpler to look through the docs to reason about. I also want to praise the author of the library (Jeremy Evans), his support through the IRC is second to none, you can talk directly with him pretty much on a daily basis. And even after 8+ years, the project is still constantly being updated (last commit 4 days ago). I haven't seen too many project of this calibre especially when it is ran mostly by a single person.
