Airplane seems to be a more general purpose product for building internal tools, whereas Evidence is really focused on reporting and analysis workflows. At a quick glance, there are 4 things that come to mind for Evidence: 1. Text support, including support for putting values from your data into sentences (narrative-driven reporting) 2. More analytics data sources supported (like DuckDB, SQLite, and CSVs) 3. I would imagine that our charting library has a wider selection, with options for more complex visuals - we spend a lot of time and effort here! 4. Evidence produces a static site, so pages and data are pre-built and users don't need to wait for queries to run when they're using the site

Airplane looks to have some great form-building and interactive app features, so I think it just depends on the problems you're trying to solve
