Which LLMs and frameworks does Flowlines support?
Any of them. Because Flowlines reads traces rather than your code, the model and framework don't matter, OpenAI, Anthropic, open-source models, LangChain, LlamaIndex, CrewAI, LangGraph, Vercel AI, or a custom loop all work the same way as long as their traces land in Langfuse or an OTEL pipeline.
Framework-agnostic isn't a marketing line here, it's a consequence of the architecture. Flowlines never sees your code, only the traces your stack emits. If a session shows up in your trace store, Flowlines can read it.
That covers raw API calls, the major agent frameworks (LangChain, LlamaIndex, LangGraph, CrewAI, Vercel AI), and bespoke agent loops. Mix providers and models freely, the signals and cohorts are computed over behavior, not over a specific SDK's schema.
