wtf is sealos?

Sealos lets you run applications and databases in the cloud without needing to understand or manage the underlying infrastructure. Think of it as a cloud platform that behaves like a personal computer, you log in, launch what you need, and it just runs. You can deploy a web server, spin up a MySQL or MongoDB database, or run something like WordPress, often in under a minute through a web interface. Under the hood, it is built on Kubernetes, which is an industry-standard system for managing containerized applications at scale. Normally, setting up and operating Kubernetes is complex and requires specialized knowledge. Sealos abstracts that away. Multiple users (or "tenants") can share the same underlying cluster while keeping their data isolated and secure. The platform handles things like automatic resource scaling, public domain assignment for your apps, and internal networking so your applications can talk to your databases without extra configuration. This is aimed at teams and companies who want the benefits of cloud-native infrastructure without hiring a dedicated platform engineering team. A startup could use it to host their product backend and databases. A small team could deploy an internal tool like a monitoring dashboard or a low-code platform. It works for both private clouds (run on your own servers) and public clouds (shared infrastructure accessed over the internet). The key appeal is that you don't need to be a Kubernetes expert to use it, there is a visual app launcher, a built-in terminal for those who want command-line access, and a database creation tool. One notable tradeoff is that you are buying into an opinionated platform. Sealos wraps Kubernetes in its own interface and tooling, which makes things dramatically simpler but means you are operating within their ecosystem rather than managing raw infrastructure yourself. The project claims cost savings of 10-40% compared to alternatives, largely because you pay only for the container resources you use and automatic scaling avoids paying for idle capacity. There is an online demo available if you want to try it before installing anything.
