Orbiter started as static website and web app hosting, but we recently added what we call server functions (what you call serverless functions). So now you can build full stack apps. Our preferred development stack to support is the new bhvr[2] stack.
My co-worker and I started this as a side project because we were building so many sample apps, proofs of concept, and engineering as marketing apps and we were feeling more and more locked into Vercel every day. So we wanted to go back to client and server separation and when we did that, we realized most hosting providers have moved toward server-side rendering as the default.
Client-side rendering isn’t for everyone, but plenty of people still make simple websites or even complex CSR web apps and don’t want to deal with fully integrated solutions like Vercel (and Netlify now to a lesser extent). Plus they want the flexibility of choosing different tools for their frontend and backend.
This remains a fully bootstrapped side project for us, but it’s gotten the most traction of any side project either of us has worked on.
We recently added serverless functions for backend support, specifically for the bhvr[1] stack though they work with just about anything.
