I ended up actually not trying double.bot - overall I tried only cursor.sh (first with BYOK and now subscriber) and continue.dev (didn't manage to integrate own key from OpenRouter in JetBrains plugin). For me in the beginning one of the selling point is if I can bring my own key (ideally with GUI setup instead of some config file and working with OpenRouter key). Then if something is open source is also a selling point.

I would recommend update double.bot landing page to have all features shown in few gifs on the same page and 'show in action' short video' - continue.dev had actually pretty good landing page. CodeSnap is probably something similar like cursors' 'apply' but double.bot landing page feels more like documentation. Also at this stage probably worth to add additional comparison to cursor same like you have for copilot
