Building a different relationship with technology and paving the way toward intelligent operating systems. open-os develops and promotes accessible, distributed, and interoperable technologies that work across platforms, respect your data, and remain open for anyone.
Browser interface for local language models
A lightweight extension that connects to any LLM running on Ollama (Llama, Mistral, Phi, Gemma, and others). Chat with AI directly from your browser without external servers, accounts, or telemetry.
Available for Chromium browsers (Chrome, Brave, Edge).
Coming soon: Soul Protocol integration for persistent context across sessions.
Specification for portable AI identities
An open specification for portable AI identity. A standardized system of interconnected Markdown files that define an AI assistant's identity, knowledge, preferences, and reasoning patterns — independent from any specific model or provider.
Change the brain. Keep the soul.
Independent software distribution platform
App marketplace operating since 2002. Direct distribution without platform restrictions, zero commission for developers, accessible from any browser.
130M+ monthly active users · 3M+ apps · 15 languages
A project predating open-os but aligned with the same principles.
