Dify
open-sourceDify is an open LLM app platform with visual orchestration, RAG, and agent workflows you can self-host.
Dify combines a visual builder for prompts, datasets, and tool-using agents with deployment options that include self-hosting and cloud. Teams connect models from multiple providers, ingest documents for retrieval augmented generation, and expose assistants via APIs or embeddable widgets.
The open-source edition is suitable for enterprises that need data residency and customization, while managed tiers add convenience. Features cover evaluation traces, versioning, and collaborative editing of app logic.
Dify fits startups and internal platform groups that want a midpoint between no-code speed and developer control—especially when shipping knowledge-grounded assistants without writing every orchestration line manually.
