Multi-Provider LLM Engine
Route prompts to Gemini, OpenAI, Anthropic, Groq, DeepSeek, Qwen, GLM, Kimi, or local Ollama models — all through a single unified interface powered by LiteLLM.
Build, deploy, and orchestrate AI agents with native tool access, multi-provider LLM routing, and a sandboxed Linux environment.
OpenZess is not just another chatbot UI. It is a full operating system for AI agents — a complete environment where autonomous agents can execute code, browse the web, manage files, and even control a virtual desktop.
Built by Debjit Das, OpenZess combines the power of modern LLMs with native system-level capabilities that no other open-source project offers.
