My understanding is that dev containers are more about configuring your development environment with the right toolchains to build and run services.

Tilt is a monitor process that builds and starts your services, with a hot-reload loop that rebuilds and restarts your services when the underlying code changes. The hot reload loop even works for statically compiled languages.

Yeah it would be really useful to have in the readme what kind of problems this solves that dev containers don't solve already
