Dify

Dify is an AI app platform for developers and teams building production LLM applications. From the pricing page, it positions itself around app building, RAG pipelines, integrations, observability, and workflow-based agent apps rather than simple chat.

You can use it as a cloud service or deploy it self-hosted. Getting started appears straightforward: sign up for the cloud sandbox or choose a paid workspace plan, with support for multiple model providers including OpenAI, Anthropic, Llama 2, Azure OpenAI, Hugging Face, and Replicate.

The platform looks strongest for teams that want a managed way to build and operate AI applications with document handling, logs, and app publishing. The pricing page also suggests meaningful limits by plan, especially around message credits, workspaces, team members, knowledge documents, and API rate limits.

What is less clear from this page is the full extent of the self-hosted edition, the exact pricing for enterprise arrangements, and whether Dify itself is open source under a specific license. It also does not indicate MCP support. If you only need a simple chatbot or a purely consumer-facing assistant, Dify may be more platform than you need; it seems aimed more at builders and teams shipping AI apps.
