Hey! Creator of Dub here! Appreciate the sentiment, also great point in the replies about link shorteners leading to spam.
My plan with Dub is to keep this running at a sustainable pace for as long as possible, and I believe it's possible for a few reasons:
- Operating costs for Dub are quite low at the moment, thanks to Edge Functions (https://vercel.com/edge) + Redis.
- I'm leaning into the custom domains & self-hosted aspect with the freemium model – where enterprises and businesses would be able to get set up with a custom domain link shortener super easily.
- Agree that individual short links are definitely not sustainable in the long run, I might set a rule where randomly-generated links > 30 days get deleted, to save it you'll either need to make an account (to prevent spam) or set up your own domain.
