PromptOS is an AI-driven Linux installer designed to generate a unique, hardware-aware installation blueprint for each deployment. Unlike traditional installers that rely on static menus and preselected packages, PromptOS operates as a minimal live bootstrap, engaging users through high-level questions and interfacing with large language model (LLM) providers to tailor the installation process dynamically. This approach addresses the limitations of static installation media, such as outdated drivers and generic package selections, by ensuring that each system setup is current and customized to the target hardware and user requirements.
The installer features a text-based user interface (TUI) wizard, built with Go and Bubble Tea, which compiles into a static binary suitable for use in a lightweight live environment. PromptOS supports pluggable LLM clients, enabling integration with providers like OpenAI, Anthropic, Gemini, or local Ollama instances. The system produces structured JSON blueprints that are validated before execution to ensure reliability. Its execution path includes disk partitioning, chroot bootstrapping using tools such as archinstall, debootstrap, or pacstrap, and configuration file application.
Additional capabilities include closed-action install triage, bounded auto-healing for installation issues, boot-time rescue options, and explicit disk-wipe confirmation for safer operations. Continuous integration is incorporated through GitHub Actions, which builds the actual installation image, emphasizing a workflow that keeps the installer lightweight while delegating package management and stack tracking to upstream sources and LLM models.
PromptOS is intended for users who need flexible, up-to-date Linux installations that adapt to specific hardware and user needs, offering a streamlined and modern alternative to maintaining custom distribution images or relying on static ISOs.
PromptOS is a Hosting, deployment & PaaS product. It focuses on automating and customizing Linux installations using AI to avoid static, outdated install media. PromptOS is an open-source project aimed at linux system administrators. The project is open source (Open Source). It runs on the web and the command line.
It is developed by HappyMonkey AI, and the product first shipped in 2026. Among its 9 catalogued features are AI-driven install, custom blueprints, and hardware detection.
