## Choose when

### Choose moby if…

- moby is primarily Go; Sponsio is Python.
- Tags unique to moby: containers, docker, go, golang.
- Also covers Developer Tools.
- moby ships Docker support for self-hosted deployment.

### Choose Sponsio if…

- Sponsio is primarily Python; moby is Go.
- Tags unique to Sponsio: agent-guardrails, agent-harness, agent-runtime, agent-safety.

## When NOT to use moby

- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use Sponsio

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
