Dev builds a fix so AI agents don't need rewriting when you switch frameworks
Building an AI agent tied to one framework — like LangChain or AutoGen — means you have to rewrite it almost from scratch if you switch. One developer got frustrated with this and started building a shared layer that works across frameworks. The goal is to write your agent once and move it anywhere.
Right now, most AI agent frameworks don't talk to each other. Logic written for LangChain won't run on AutoGen without significant rewrites — it's a bit like writing a mobile app that only works on one phone brand. Every time the ecosystem shifts (and it shifts fast), developers are forced to redo work they've already done.
The developer behind this project is building an abstraction layer — a middle layer that holds the agent's core logic (how it calls tools, remembers things, and decides what to do next) separately from any specific framework. Switching frameworks would then only require swapping the thin connector, not the whole agent brain. For anyone building agents that need to stay useful as the AI tooling landscape keeps changing, this kind of portable design could save a lot of rework.
Key points
- AI agent frameworks like LangChain, AutoGen, and CrewAI are not compatible with each other
- Switching frameworks today means rewriting most of your agent from scratch
- This project builds a middle layer that separates agent logic from the framework it runs on
- Once built, the same agent core can be reused across different frameworks
- Especially useful now, since the AI framework landscape changes quickly
Quick term guide
