Choose rebuff if…
- License: rebuff is Apache-2.0, GPTRouter is MIT.
- Tags unique to rebuff: prompt-injection, prompts, security, typescript.
- 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.
- 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.
Choose GPTRouter if…
- License: GPTRouter is MIT, rebuff is Apache-2.0.
- Tags unique to GPTRouter: langchain, anthropic, llama-index, azure-openai.
- Also covers Computer Vision.
- - Use GPTRouter when you need to manage a variety of language models (OpenAI, Anthropic, Azure) and image models (Dall-E, SDXL) under one hood.
When NOT to use GPTRouter
- - Avoid using GPTRouter if your project exclusively requires working with non-supported models that are not OpenAI, Anthropic, Azure for language or Dall-E, SDXL for image.
- - Do not use it when you seek tools that have more extensive documentation beyond TypeScript. Users looking for a wider range of integration examples and detailed guides in other languages may find GP
