Choose SPTAG if…
- SPTAG is primarily C++; moby is Go.
- License: SPTAG is MIT, moby is Apache-2.0.
- Tags unique to SPTAG: space-partition-tree, fresh-update, c++, neighborhood-graph.
- Also covers Vector Databases.
When NOT to use SPTAG
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- 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 moby if…
- moby is primarily Go; SPTAG is C++.
- License: moby is Apache-2.0, SPTAG is MIT.
- Tags unique to moby: go, docker, golang, containers.
- Also covers LLM Frameworks.
- 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.
