Shared compatibility

  • Python · fact-checker: Python runtime · rebuff: Python runtime

Choose fact-checker if…

  • fact-checker is primarily Jupyter Notebook; rebuff is TypeScript.
  • Tags unique to fact-checker: python, jupyter notebook.
  • Leaner open-issue backlog (0).

When NOT to use fact-checker

  • Last GitHub push was 992 days ago (dormant maintenance, Oct 23, 2023). Validate activity before betting a new project on fact-checker.
  • Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
  • LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

Choose rebuff if…

  • rebuff is primarily TypeScript; fact-checker is Jupyter Notebook.
  • Tags unique to rebuff: llmops, prompt-injection, prompts, security.
  • Also covers Evaluation & Observability.

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.
  • 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.
  • Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
