For everyday users who want a simple, free way to experiment with AI agents and RAG, Langflow wins hands-down because it's open-source, has a free cloud option, and is easier to start with. Dify.ai is more powerful for teams building production-ready workflows, but its free tier is very restrictive and it requires more technical skill. The single biggest difference: Langflow is designed for quick tinkering and sharing, while Dify is built for serious, scalable deployment.

Common questions
Langflow is easier to start with for this task — you can use a pre-built RAG template in minutes. Dify offers deeper RAG optimization (custom chunking, embedding models) but requires more setup. For a simple PDF chatbot, Langflow is the better choice.
No. Both tools are designed for desktop browsers only. You can publish an app from either tool that users can access on their phone, but you cannot build or manage workflows on a mobile device.
Langflow is cheaper because it's open-source and has a free cloud option that's actually usable. Dify's free tier is very restrictive, so you'll likely need to pay $59/month or self-host (which requires technical skills).
No. Langflow is a visual drag-and-drop tool. You can build complete AI workflows without writing any code. However, if you want to customize components, you can use Python.
Dify is better for this because it's built for production deployment, team collaboration, and has strong API integration. Langflow can prototype it quickly, but Dify is more reliable for a live customer-facing system.
Langflow is the best free, beginner-friendly choice for everyday AI tinkering; Dify is the pro tool for teams building production AI apps.
If you're just starting out or want to experiment without spending money, go with Langflow — it's free, easy, and you'll have something working in minutes. If you're building a serious AI product for your business and have a bit of technical help, Dify is the more powerful choice, but be ready to pay or learn Docker.
