I feel like that web only is a positive way forward. If only it was possible to prove nothing goes back to the server I think it would gain a lot more trust. Though companies who want to see your data might not be so keen. On my phone, but will try it out when I get home.
15 years from now, will this site still be up?
Will you be able to open your projects from today, then?
I think web only is a really compelling way to get someone to try a product, but I’d much rather install a tool like this. Unless you could host the site yourself, of course.
