Built a tool to compare agent frameworks side-by-side with identical prompts
AU1CII · reddit · 2026-09-22
Reddit user AU1CII built a small tool to answer a core question: how much does agent architecture actually matter in practice?
- It runs the exact same prompt across different frameworks, models, reasoning modes, and tool policies, then displays execution traces side by side
- Currently supports native agents, LangChain / LangGraph, Plan/Execute, Self-Critique, AutoGen, and CrewAI
- Still early-stage, the goal is making architectural differences visible and easier to evaluate
- The author, new to agent systems, asks for feedback on useful comparison dimensions
