Best self-hosted and local AI companions

Companion apps you can run on your own machine or against your own model, so no conversation has to leave your hardware.

8 apps rankeadasPuntuación editorial, no espacios pagados

Cómo los elegimos. Everything here can run locally — either self-hosted, on a local model, or against your own API key. This is the shortest list in the directory on purpose: most companion apps are cloud-only and cannot honestly be listed here. La lista se genera a partir del mismo catálogo que usan las páginas de categorías, así los números de aquí y de allá siempre coinciden.

  1. SillyTavern

    4.3
    Free

    4.2

Preguntas frecuentes sobre esta lista

How many apps are on this list?

8 apps meet the criteria for “Best self-hosted and local AI companions”. We would rather publish a short, honest list than pad it with apps that only half fit.

Which one should I pick first?

SillyTavern tops this list with an editorial score of 4.3 out of 5 and costs Free. That is a starting point, not a verdict — the card under each entry says who it actually suits.

What is the cheapest option here?

SillyTavern, at Free — and 8 of the 8 listed apps have a free tier you can try first.

Can I sort these by something else?

Yes. The category pages carry the full five-way filter — medium, orientation, price, platform and sort — and the numbers on this list match the numbers there, because both are computed from the same catalogue.

Lo que esta lista no es. Nada aquí es un espacio pagado. Si un sitio alguna vez nos paga, es una colocación patrocinada etiquetada que queda fuera del ranking, nunca dentro. Los precios provienen de páginas de precios públicas y se etiquetan como no verificados hasta que uno de nosotros los comprueba. Cómo funcionan nuestras decisiones editoriales.
