Earlier quoted context omitted.

Interesting. Does it only work with known frameworks like Next, React etc. or could I use it with my plain Node.js app which produces browser-output?

No, doesn't use work with server-side only apps.

It's a server-side app whose GUI is in the browser, a bit like Electron or what have you.

I guess my question is does Tidewawe only work with a fixed set of known "frameworks" like React and Next, or is it a more general purpose tool for analysing an app based on its source-code and the HTML it produces for the browser?

I use Playwright to intercept all requests and responses and have Claude Code navigate to a website like YouTube and click and interact with all the elements and inputs while recording all the requests and responses associated with each interaction. Then it creates a detailed strongly typed API to interact with any website using the underlying API. Yes, I know it likely breaks everybody's terms of service but at the…

I would love it if you had time to publish it!

I love how HN is loving this idea when it's the exact same thing Anthropic and OpenAi (and every other llm maker) did. It's God's gift to them when it lets them bypass ads and dl copyrighted material. But it's Satan's curse on humanity when the Zuck does it to train his llm and dl copyrighted material.

You conflate web crawling for inference with web crawling for training.

Web crawling for training is when you ingest content on a mass scale, usually indiscriminately, usually with a dumb crawler for scale's sake, for the purposes of training an LLM. You don't really care whether one particular website is in the dataset (unless it's the size of Reddit), you just want a large, diverse, high-quality data mix.

Web crawling for inference is when a user asks a targeted question, you do a web search, and fetch exactly those resources that are likely to be relevant to that search. Nothing ends up in the training data, it's just context enrichment.

People have a much larger issue with crawling for training than for inference (though I personally think both are equally ok).

The DevTools MCP project just recently landed a standalone CLI: https://github.com/ChromeDevTools/chrome-devtools-mcp/blob/m... Great news to all of us keenly aware of MCP's wild token costs. ;) The CLI hasn't been announced yet (sorry guys!), but it is shipping in the latest v0.20.0 release. (Disclaimer: I used to work on the DevTools team. And I still do, too)

The big upside of the MCP is that it connects to already open browser windows. I tried the skill but it always tries to open new windows. Is there a way to get the `--autoConnect` behaviour with the CLI?
