Missing some of the other general purpose use cases that devs would want to build - which wouldn't fit into bun's flavor of hosting.
Getting early funding is cool , but I'm not sold on the business model. Tons of hosting providers exist, corps are unlikely to switch meaning your stuck selling to hobbyist / small developers.
That said, they just need to stay alive until aquired
Another thing is that he intends for Bun to be a drop-in replacement. Why •wouldn't* you switch hosting providers for a free massive boost in performance?
So I'm going to convince upper management to let me host our apps in a new unknown hosting provider vs the AWS contract we already likely have ? Maybe if your a CTO at a startup you could pitch this, but for the most part I'd imagine people will end up using Bun on existing hosts like AWS and Azure.
Nothing stops AWS from implementing whatever makes Bun hosting faster on their own platform. Don't get me wrong, I REALLY love Bun as an idea. I'm just not sure it'll make money.
