nanobot (lightweight, self-hosted personal agent)

It does the same as OpenClaw or Hermes Agent, an assistant that lives on your server and answers you by chat, but with a core small enough to read in full and understand what it does before giving it access to anything. It has documentation in Spanish and a guide to install it with no technical experience, which is rare in this category. For an agency it works as a first internal agent: summarize, remember to-dos, run tasks at fixed times. The hidden cost: the agent is free, the model is not; you need an API key from a provider or a local model.
