Self-host on a Cube

Self-host the open-source AI assistants, agents, frameworks, and chat UIs people run on a Krova Cube — OpenClaw, Hermes Agent, n8n, Agent Zero, Open WebUI, Letta, Open Interpreter, OpenHands, CrewAI, ZeroClaw, NanoClaw.

Open-source AI tools you can run on a Cube. Every entry here is self-hostable on Ubuntu 24.04, with a verified install command, sizing recommendation, and the path to expose it at your own domain through the Krova edge. The Cube provides the always-on server; the tools provide the assistant, agent, chat UI, or workflow engine.

All self-host tools

  • OpenClaw — An open-source personal AI assistant that lives on your server and meets you in Discord, Telegram, WhatsApp, Slack, iMessage and 20+ more channels. About 390,000 stars on GitHub.
  • Hermes Agent — An open-source AI agent from Nous Research with persistent memory and self-created skills, reachable 24/7 from Telegram, Discord, Slack, WhatsApp, Signal, email and the CLI.
  • n8n — The open-source workflow automation platform with native AI agent nodes and 1,500+ chat-app and SaaS integrations. Workflow-as-a-personal-assistant.
  • Agent Zero — Open agentic framework — gives the agent a full Linux computer inside Docker, with browser DOM annotation, time-travel snapshots, and a plugin hub.
  • Open WebUI — The closest open-source equivalent to ChatGPT — a self-hosted chat interface for any LLM, with multi-user support, RAG across nine vector databases, and plugins. About 152,000 stars on GitHub.
  • Letta — Stateful agents with first-class memory that survives across sessions and machines (formerly MemGPT). Slack, Telegram, Discord and custom channel adapters built in.
  • Open Interpreter — Code-execution agent that runs shell commands, edits files, and drives browsers from a single prompt — closer to a coding agent than a chat companion.
  • OpenHands — Self-hosted web control center for coding agents and automations — agent-agnostic, drives Claude Code, Codex, and any ACP-compatible agent from a single UI on port 8000.
  • CrewAI — Python framework for orchestrating role-playing, autonomous AI agents that collaborate on tasks — build it yourself rather than run a finished agent.
  • ZeroClaw — Lightweight open-source personal AI agent in a single Rust binary, connecting to 70+ LLM providers and 30+ chat-app channels. Dual-licensed MIT OR Apache-2.0.
  • NanoClaw — Open-source personal AI agent that runs every active session in an isolated Docker container, with 18+ chat-app channels added on demand as skills.
