FastGPT FAQs
- Is FastGPT the same as Dify?
- Both are open workflow builders but differ in architecture and community plugins. Pilot both on identical RAG corpora before standardizing.
- Can FastGPT satisfy SOC2 by itself?
- No. Compliance follows your deployment controls, logging, and access policies—not the GitHub README alone.
