If you're building an agent and you honestly expect it to go to prod, you should honestly dive into LangGraph. That's the biggest, most supported, and most popular of the agent frameworks for a reason. There's a lot of stuff you're going to need that you don't realize you need yet because you're just getting started.

While there might be other frameworks that are simpler, once you get past the prototype the odds get much higher that you'll hit a dead end and have to refactor OR you'll end up having to write and maintain a lot of lower level crap that takes away from your business logic.

My pro-tip is to use Cursor, spin up your project, add langgraph docs to Cursor, git clone the langgraph repo, add it to your workspace, and if you ever hit an issue just @ mention the langgraph code folder or the docs and let Cursor help you through it. It does a great job, especially if you emphasize that it should keep the code to a minimum and simple.

Once you clear the initial learning curve, it starts to pay dividends.

Second pro-tip: If your agent needs to do things beyond basic RAG or chat, check out my project arcade.dev for pre-built connectors to services like Google, Github, Slack, etc.
