What's a low-cost way to host custom web apps or MCP servers built for client work?

One member hosts their client-facing web apps on a small server (about $6 a month) tied to their company website, noting that resources exist explaining how to set this up step by step even without a developer background. Another member uses Google Cloud (falling under the free tier) to host their MCP servers, but described it as clunky—requiring redeployment via terminal every time changes are made or a new client needs to be authorized, creating friction even though it's functional.
