Good fit when
- You are working with Ruby on Rails applications and need a tool specific to this environment
- Integration into existing production data flows within Rails applications is desired
Avoid when
- If your application is not built using Ruby on Rails, Leva may not be the best fit
- For scenarios requiring broader cross-platform support or with non-Rails production data integration needs, consider other tools
