AIEUSDownload
AIEUS is in beta. It works, but anything about it can change in any new release, including its features, screens, setup and licence terms, and some parts are not yet proven on every installation. Keep in mind: A version you already have keeps the licence it came with, and it changes only when you install a new release.
AIEUS is free to download as a prebuilt package. Under its licence, you can run it yourself on your own computer, use it in your organization, and build your own apps and modules on it. Keep in mind: Offering AIEUS, or a changed or derived version of it, to others as a commercial general-purpose platform for building and running their own apps, AI agents or workflows needs a separate commercial licence, including any free tier of that offering. As its instructions set it up, only the computer it runs on can reach it. Running it can still cost you: the computer and software it runs on, and the AI services you connect on your own accounts. Parts made by others keep their own licences.
There is no setup app to double-click. Your AI coding assistant, Claude Code or Codex, installs it with your approval, following the instructions that come with each release, and updates it to later releases the same way, taking a backup first. Keep in mind: You need one of these assistants, usually a paid service, and a Windows PC running Docker Desktop with WSL or a Linux computer running Docker. The instructions do not cover Macs, and first start needs internet access. Nothing updates on its own. Installation requires administrator access (sudo in Linux or WSL).
The current release
The current release is aieus-dbbc44c52092-amd64-e2a42f3e10b5, a package of about 430 MB for computers with 64-bit Intel or AMD processors. Keep in mind: Unpacking and installing it needs several GB of free disk space, and this page has no package for computers with ARM processors.
Its SHA-256 checksum is 33eb59b7b0ef521fe202cb018ef8e7377a9ad6594a4a3483d7440db170585564. The release instructions have your assistant check the download against it, and the files inside against their own checksum list, before installing anything. Keep in mind: The checksum comes from this site too, so a match shows the download arrived intact, not who made it.

Installing and updating
To install it, copy this request into Claude Code or Codex. Keep in mind: The request asks your assistant to check the download and to stop for your approval, but the assistant still does the work, so read what it proposes before you say yes.
Install AIEUS on this computer. Read https://artifexsystems.ai/downloads/aieus/releases.json and download every file it lists for the newest release, from the same folder, checking each file's checksum before unpacking. Then follow the instructions file it names, starting with its checks. Ask me before each step that changes anything, and ask me which email to use for the administrator account.
To update an installation you already have, copy this request instead. Keep in mind: Updating an installation that already holds data is not yet proven on every installation, so the request has your assistant take a backup and check it first.
Update my AIEUS installation to the newest release listed at https://artifexsystems.ai/downloads/aieus/releases.json. Download every file it lists for that release and check each checksum, then follow the update section of the instructions file it names: take a complete backup first and confirm it can be read. Ask me before each step that changes anything, and stop and tell me if the update is refused.
Licence
AIEUS and its first-party Core and Root module code are licensed by Artifex Systems LLC under the Business Source License 1.1 (BUSL-1.1).
The licence permits production use for any purpose except to provide a Commercial Platform Service. Permitted production uses include running AIEUS for your own business; developing, distributing and hosting applications that perform defined functions for their users, including paid applications; and providing paid installation, customisation, training, maintenance or support for a customer's permitted use. Keep in mind: A Commercial Platform Service is a commercial offering in which you operate AIEUS, including a modified or derivative version, and provide third parties with its general-purpose platform capabilities for creating and operating their own applications, agents or automated workflows; a free tier of a commercial offering is part of that offering. Installation or administration on a customer's behalf remains permitted when the customer controls its installation and the provider supplies professional services rather than access to the provider's platform offering. A Commercial Platform Service does not become permitted solely because its components run in a customer-controlled cloud account.
A Commercial Platform Service needs a separate commercial licence.
The AIEUS source repository is private today.
