Choose rebuff if…
- rebuff is primarily TypeScript; IB4LLMs is Python.
- Tags unique to rebuff: llm, llmops, prompt-engineering, prompt-injection.
- Also covers Vector Databases.
When NOT to use rebuff
- rebuff is archived on GitHub. Prefer an active alternative unless you maintain a private fork or need a frozen dependency.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
- 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.
