Open-Source AI Agent Stack
Build a fully self-hosted AI automation pipeline using Ollama for local models, OpenClaw for autonomous agents, and n8n for workflow orchestration with no vendor lock-in, no per-message fees, and complete data privacy.
Why these tools work together
Ollama gives you the foundation: fast, free, private AI inference running on your own hardware. No API keys, no usage fees, no data leaving your network. OpenClaw turns that raw inference power into an agent that can actually do things: monitor inboxes, review code, manage tasks, and chain together multi-step workflows across 50+ platforms. But agents need triggers and orchestration. n8n provides the glue: visual workflow automation that fires agents on events, routes their output to the right places, and handles the conditional logic between steps. The result is a complete AI automation stack where you own every layer, from the model weights to the business logic, with zero recurring software costs.
How it works
- 1
Deploy open-source models locally (Llama 3, Mistral, or Phi) for fast, private inference with no API costs
A local LLM API endpoint running on your hardware
- 2
Configure OpenClaw to use local Ollama models as its AI backend, set up messaging integrations and agent skills
An autonomous agent connected to your messaging platforms and developer tools
- 3
Build visual workflows that trigger OpenClaw agents on events like new emails, Slack messages, GitHub PRs, and scheduled tasks
Automated pipelines that orchestrate AI agents across your business tools
Tools in this stack
Local LLM runtime that runs open-source models on your own hardware with zero API costs
A simple local model runner and manager that makes downloading and serving local LLMs much easier than doing everything by hand.
Autonomous AI agent platform that turns local or cloud models into agents acting across your apps
OpenClaw is a free, open-source AI agent platform that runs autonomously across messaging apps and developer tools. It is the fastest-growing open-source project in history, best suited for technical users who want full control over their AI automation stack.
Visual workflow automation that connects agents to business tools with trigger-based pipelines
n8n is the technical team's automation platform: flexible, scriptable, and available as both cloud and self-hosted. It is one of the strongest choices for builders who want more control than SaaS automation tools usually allow.
