The tool's approach from first principles can be time-consuming compared to using established frameworks. - If you need scalability or cloud capabilities such as easy scaling with demand, this tool will not provide these features since it strictly operates on local infrastructure. ## Common questions ### What is the difference between leon and agents-from-scratch? leon: Leon is your open-source personal assistant. agents-from-scratch: Build AI agents locally without relying on frameworks or cloud APIs..
