AI Horde: sovereignty score and 8 European alternatives

AI Horde is a community service for generating images and text with generative AI models. Volunteers share their computing power through so-called workers, and the middleware routes each request to an available machine. People and developers use it through a web interface or a REST API. A points system called kudos sets queue priority; anonymous use is possible, at the lowest priority.

AI Horde is developed by Haidra, a volunteer-run non-profit that states it is registered in Luxembourg. The source code is licensed under the AGPL-3.0. The main offering is the free public service at aihorde.net, where requests are processed by volunteers' computers. No fixed processing location or data processing agreement was found on the pages consulted, so the public service offers no guarantee that prompts stay in the EU. The middleware can also be deployed privately in an organisation's own environment (Python, PostgreSQL, Redis, Docker); a self-run instance keeps prompts within your own environment. Development was co-funded through NLnet and the EU's NGI Zero Core programme.

Why digital sovereignty matters with AI Horde

AI Horde is headquartered in LU and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

AI Horde hosts data outside the EU (OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

AI Horde is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs AI Horde together with your other vendors and gives a total score, a heatmap and the main risk drivers.
