Privacy
Some privacy controls exist, but vendor-hosted infrastructure still handles a meaningful share of the data flow.
Maximum privacy — all inference runs locally, zero data leaves your machine.
Google ADK pros
- Official Google backing
- Built-in evaluation framework
- Multi-agent orchestration
LocalAI pros
- Highest privacy possible — fully air-gapped operation.
- No GPU required — runs on CPU, Apple Silicon, or any hardware.
- OpenAI-compatible API — drop-in replacement for many tools.
Google ADK cons
- Python-only
- Development framework, not ready-to-use assistant
- Google Gemini API dependency
LocalAI cons
- Not a full agent — it is a model runtime, not an agent framework.
- Performance limited by local hardware.
- No built-in memory, planning, or tool-use — requires a framework on top.
Google ADK gotchas
- You should expect ongoing hosting, uptime, and secret-management work if you deploy it for real users.
LocalAI gotchas
- LocalAI is a model server, not an agent. Use it as the LLM backend for OpenClaw, AutoGPT, or similar.
- Model download sizes range from 4GB to 70GB+ — check disk space first.
