Best For

ai-stack-compare is best for crewai, multi-agent workflows where OpenClaw compatibility matters.

Not Ideal For

Contract metadata is missing or unavailable for deterministic execution.

Setup snapshot

  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

ai-stack-compare

The same small task built four ways — no framework, LangChain, LangGraph, CrewAI — on the same local model (qwen3:4b-instruct via Ollama) and the same retrieval, then measured side by side.

The task: answer a Laravel docs question in a few sentences with inline citations, and refuse when the docs don't cover it.

| Implementation | Layer it represents | Shape | |---|---|---| | stack/impl/plain.py | provider API, no framework | retrieve → one chat call | | stack/impl/langchain_lcel.py | framework glue | LCEL: retriever | prompt | model | parser | | stack/impl/langgraph_graph.py | orchestration (graph) | retrieve → grade → rewrite once → generate or refuse | | stack/impl/crewai_crew.py | orchestration (multi-agent) | researcher agent with a search tool → writer agent |

Everything that isn't the framework is shared: stack/retrieval.py (Chroma + bge-small, one section per chunk), stack/common.py (prompt, refusal sentinel, result type). So differences in the numbers are differences the framework made.

Measuring fairly

Frameworks hide how many model calls they make. Rather than trust each one's callbacks, stack/proxy.py sits between every implementation and Ollama and counts requests and tokens the same way for all of them.

make install corpus index
python -m stack.compare                  # all four
python -m stack.compare --only plain langgraph

Prints a table per implementation — lines of code, p50 seconds per question, LLM calls per question, tokens per question, refusals on the unanswerable questions, false refusals on the answerable ones, errors — and writes every question's row to results/compare-*.csv.

questions.jsonl has 8 answerable and 3 deliberately unanswerable questions. It's a smoke test for comparing stacks, not an eval set; for that see rag-eval-gate.

The rule this is meant to make concrete

For every layer you add, name the constraint it solves that the layer below can't. Here:

  • LangChain buys composable pieces and a large integration catalogue. For a single retrieve-then-answer call it mostly moves the same code into different shapes.
  • LangGraph earns its place when the flow branches — grade, retry, refuse without generating. That's a real behaviour the plain version doesn't have, paid for in extra model calls.
  • CrewAI is built for several roles coordinating over a long task. On a one-shot question, watch the calls-per-question column.

The model, the retrieval and the prompt matter more than any of these. Start with plain.py and climb only when a rung can't hold the task.
