Muxi

MUXI is an open source application server for AI agents, described by its makers as Docker for AI agents. A developer declares agents, tools, memory, knowledge and triggers in YAML as a unit called a formation, then deploys it with the single command muxi deploy and builds a product on top through APIs and SDKs. The stack has four parts. The Server runs formations with zero downtime deployment and self healing. The runtime executes them. A command line tool manages secrets and formations. A registry lets users pull pre built formations and publish their own with semantic versioning. A component called the Overlord routes, decomposes and coordinates the work of agents, and tools connect through MCP. REST and streaming interfaces are provided, along with SDKs for Python, TypeScript, Go, Ruby, Java, Kotlin, Swift, C#, PHP, Dart, Rust and C++. It is aimed at developers and teams who want production infrastructure for agents rather than framework code, including multi tenancy and observability. MUXI is self hosted and works with any large language model provider. Installation is through Homebrew or an install script for macOS, Linux and Windows. The documentation carries no pricing page, and the project is presented as open source, so no paid plans are published.
