Choose moby if…
- moby is primarily Go; PiSSA is Jupyter Notebook.
- Tags unique to moby: go, docker, golang, containers.
- Also covers Developer Tools.
- moby ships Docker support for self-hosted deployment.
When NOT to use moby
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- 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.
Choose PiSSA if…
- PiSSA is primarily Jupyter Notebook; moby is Go.
- Tags unique to PiSSA: fine-tuning, jupyter notebook, quantization, peft.
- Also covers Vector Databases.
When NOT to use PiSSA
- Last GitHub push was 377 days ago (dormant maintenance, Jun 30, 2025). Validate activity before betting a new project on PiSSA.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
