Software you can read is software you can trust.

Magus is open at the core: an auditable, self-hostable codebase, your choice of models, and your data in the jurisdiction you choose. The capability is the point. Owning it is the spine.

verify it yourself

Your data. Your models. Your jurisdiction.

Not promises in a pitch deck, things you can verify: the license, the source, the compose file, and the privacy policy.

Open core

The codebase is Apache-2.0 and auditable. No black box, no lock-in. Inspect exactly what runs.

apache-2.0

Any model

Route to open weights or frontier models. Every provider is country-classified; you hold residency per task.

US / EU / CH / gated

Self-hostable

Run the whole stack yourself with one compose file. Your hardware, your rules, fully offline-capable.

docker compose up

Your data

Export everything whenever you choose, with no lock-in. Host it yourself, or run it on our EU cloud.

EU · export anytime
the bet

Not a black box. Yours to inspect, run, and own.

The best AI tools are built in the open, with the people who use them. Magus is yours too, shape it with us.

data privacy

Hosted in the EU, and not used to train AI.

The short version of the privacy policy and terms: where your data lives, what we don't do with it, and how to take it with you.

EU-hosted

Servers and backups in Frankfurt, Germany. No US silo.

Never trained on

Your conversations are never used to train AI models, by default.

You own the output

Full commercial rights to everything the AI generates stay yours.

Export anytime

Download everything in a machine-readable format whenever you choose.

Deleted on request

Wiped from backups within 30 days of closing your account.

GDPR + Swiss nFADP

Standard contractual clauses with every processor.

Named subprocessors

A short, named list: hosting, model gateway, payments. No brokers.

Swiss jurisdiction

Governed by Swiss law, with EU consumer protections preserved.

honest by default

What's open, and what's not.

Open-core, stated plainly. The product is open; the commercial wrapper is not.

◬ open source

  • Marketing, CMS, this website
  • Managed Swiss hosting & support
open & community

We’re building Magus in the open.

A small Swiss team, building with the community. The core is open source on GitHub and the conversation lives on Discord. Come shape it with us.
