6 Open Source AI Agents — Which One Should You Use?

There are now six serious open source projects competing to be the brain of your personal AI assistant — and they're all very different. In this video, I compare OpenClaw, NanoClaw, ZeroClaw, OpenFang, Hermes Agent, and Nanobot across the four dimensions that matter most: cost to run, security, open source model support, and ease of setup. By the end you'll know exactly which one fits your situation — whether you care about running on a $10 Raspberry Pi, enterprise-grade security with 16 defense layers, local open source models, or just getting something running in 10 minutes. All six projects are MIT licensed. You own your data, you control your costs. Note: This video is generated by AI. I designed a workflow that uses OpenCode to investigate open-source repositories to write a script about public codebases. Some of the information in this video may be inaccurate. If you maintain one of the projects I cover and notice a discrepancy with what the video says and what the codebase is, please leave a comment and I will investigate.
