Comet Lab Atlas

An open-source platform for building LLM apps and agentic workflows on a visual canvas.

Dify is a platform for building AI applications without assembling every piece by hand. A visual canvas wires together prompts, models, RAG, and tools into agents and workflows, and the result is exposed as an app or an API.

It bundles model management, a knowledge base, and observability, so a team can go from idea to a working AI app inside one self-hostable system.

Where it's ideally used

A fit when a team wants to build and ship LLM apps quickly on one self-hosted platform, without wiring the stack together themselves.

Where it doesn't fit

The all-in-one design is constraining when you need fine control over each layer — at that point assemble the parts yourself.
