LlamaIndex Workflows

the right pick when the agent is rag- and data-heavy

free — MIT (open source)#agents-whose-core-job-is

an event-driven, 1.0-stable workflow runtime sitting on the strongest rag stack — the natural choice when retrieval, not orchestration, is the hard part of your agent.

llamaindex workflows model an agent as steps that consume and emit typed events, with the runtime routing events to subscribing steps — an async-first, clean event model that reached its first stable 1.0 release. its real advantage is what it sits on: llamaindex's data and rag stack, so when your agent is fundamentally retrieval-over-your-data, this is the most natural home. agentworkflow orchestrates multiple agents over the same event bus.

the trade-off is package sprawl — the broader llamaindex surface is large — and it reads more as a data framework with agents than a pure agent runtime. cross-provider, and strongest for data-centric agents.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

our verdict

an event-driven, 1.0-stable workflow runtime sitting on the strongest rag stack — the natural choice when retrieval, not orchestration, is the hard part of your agent.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
