Frameworks for building agents

I want to pick an open-source project for code libraries for building your own ai agents. Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - LangGraph: LangGraph is a toolkit for programmers to build AI helper programs that keep track of their own progress and memory over long tasks. It is meant for software developers who build AI agents. [Advanced setup; devices not listed; replaces fully; MIT; https://github.com/langchain-ai/langgraph] - CrewAI: CrewAI is a free, open-source Python toolkit for building teams of AI assistants that work together on tasks. It is aimed at programmers and companies who want to automate multi-step work with AI. [Advanced setup; Windows · Mac · Linux; replaces fully; MIT; https://github.com/crewaiinc/crewai] - Pydantic AI: Pydantic AI is a free Python toolkit for building AI assistants, called agents, that can use tools, return structured results, and run in a browser, terminal, voice call or background job. It is aimed at Python programmers who build AI features into their own software. [Advanced setup; devices not listed; replaces fully; MIT; https://github.com/pydantic/pydantic-ai] - Mastra: Mastra is a free toolkit that programmers use to build AI-powered apps and assistants (called agents) in the TypeScript programming language. It is aimed at software developers who want to take an AI project from prototype to a production app. [Advanced setup; runs on a server you set up; replaces fully; Apache-2.0; https://github.com/mastra-ai/mastra] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/agent-frameworks.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/agent-frameworks.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
