I was tired of feeling slowed down by grepping in large Ruby code, and the artificial boundary gems create requiring a `bundle open` to keep digging. I created my own Ruby LSP to solve these problems: https://github.com/pheen/fuzzy_ruby_server
I think it works well, is stable, and I would still reach for it over Shopify's LSP personally. Feel free to use it! Though as a heads up, I don't work in Ruby much anymore unfortunately so I'm not actively working on it or accepting issues.
