There is https://shuttle.rs. Not only a framework but a tool that can generate all the web boilerplate around it, sounds lazy enough for me!

tau
Open source distributed Platform as a Service (PaaS). A self-hosted Vercel / Netlify / Cloudflare alternative.
Building your own cloud platform has many benefits, including cost savings, ownership, sovereignty, and most importantly, the ability to make your solution self-hostable. However, constructing a cloud computing platform is a long, complex, and expensive endeavor—a problem partially solved with Tau. Why only partially? Simply because, though Tau is a simple-to-deploy single binary, you still need to get that done, configure Tau, and ensure dependencies like Docker are installed. Not to mention, you have to repeat this on each host for every Tau update. If you ask me, it's not developer-friendly just yet!

swiftwave
Self-hosted lightweight PaaS solution to deploy and manage your applications on any VPS [Your own self-hosted Heroku, Vercel]
Project mention: Swiftwave: Self-hosted lightweight PaaS solution to deploy and manage your apps | news.ycombinator.com | 2025-04-29 -
I like Epinio which does the same but on top of kubernetes. It is backed by Suse and lightweight compared to KNative (which is the basis of GCP CloudRun for example), but being kubernetes based still requires more Resources than dokku or Piku. I still prefer k8s due to the vast ecosystem of mature solutions. And I can still run everything on a single box, it just needs to be a bit bigger. The new Hetzner CX42 with 8 vCPUs, 16 GB of RAM, and 160 GB of disk space for € 16.40 a month (€ 0.0273 per hour) is sufficient, and with the Kube Hetzner Project I can set up a kubernetes cluster with auto updating microos in 5 minutes.
