Privacy
Very strong privacy posture with local-first or tightly controlled deployment options.
Some privacy controls exist, but vendor-hosted infrastructure still handles a meaningful share of the data flow.
Agent Zero pros
- Docker isolation by default — safer than alternatives that run on bare OS.
- Active development with 17K+ stars and frequent commits.
- Works with local models via Ollama — no cloud dependency.
Google ADK pros
- Official Google backing
- Built-in evaluation framework
- Multi-agent orchestration
Agent Zero cons
- Requires Docker, adding setup complexity.
- Python ecosystem means heavier dependencies.
- Less polished UI compared to cloud-based alternatives.
Google ADK cons
- Python-only
- Development framework, not ready-to-use assistant
- Google Gemini API dependency
Agent Zero gotchas
- Docker requirement can be a blocker on machines with limited RAM or older hardware.
- Local LLM quality depends heavily on the model and hardware — results vary significantly.
Google ADK gotchas
- You should expect ongoing hosting, uptime, and secret-management work if you deploy it for real users.
