Self Host Blocks
Modular server management based on NixOS modules
...Indeed, SHB provides opinionated building blocks fitting together to self-host any service you'd want. Some common services are provided out of the box. SHB's goal is to make these building blocks plug-and-play. To achieve this, SHB pioneers contracts that allow you, the final user, to be more in control of which pieces go where. The promise here is to let you choose, for example, any reverse proxy you want or any database you want, without requiring work from maintainers of the services you want to self-host. To achieve all this, SHB is using the full power of NixOS modules and NixOS VM tests. ... -
