Web scraping isn't dead. Cheap scraping is.

Basic scraping scripts stopped working reliably years ago. The question is not whether web scraping is dead. It is whether the approach you are using was ever going to survive contact with modern infrastructure.

If your requests-based script gets blocked by Cloudflare or a WAF, that is not a scraping problem. That is a browser fingerprinting problem. Sites no longer just check whether your IP is on a blocklist. They check whether your request looks like it came from a real browser, with the right headers, the right TLS fingerprint, the right behavior pattern. A plain HTTP request fails that check immediately.

Why lightweight libraries fail now

Libraries like requests and BeautifulSoup were built for a web where most pages were static HTML served directly. That web mostly does not exist anymore. A significant portion of the data you actually want is loaded by JavaScript after the initial page response. If you are not rendering the page in a real browser context, you are often parsing an empty shell.

Beyond rendering, the access layer has hardened. Websites now deploy bot detection that evaluates mouse movement patterns, request timing, header ordering, and canvas fingerprinting. A headless browser running default settings fails many of these checks too. Selenium and Playwright help, but they require configuration, proxy rotation, and ongoing maintenance as detection methods evolve.

The honest answer from experienced practitioners is consistent: scraping still works, but only if you treat it like real engineering. That means understanding the access layer, not just the parsing layer.

LLMs do not fix the blocking problem

There is a common assumption circulating that LLM-based scraping solves these problems. It does not. An LLM processes HTML after you have already fetched it. If the fetch fails because of bot detection, the LLM never sees the page. The blocking problem and the extraction problem are separate, and LLMs only address the second one.

What LLMs do introduce is a different set of tradeoffs. At low page volumes and with stripped HTML, the cheapest models can be cost-competitive. But a full HTML page averages hundreds of thousands of tokens. At any meaningful scale, token costs compound fast. A pipeline processing tens of thousands of pages per month using mid-range models can cost hundreds of dollars in extraction alone, before accounting for the upstream fetch cost that both approaches share.

There is also a reliability dimension. LLM extraction is probabilistic. The same page run twice may return different field values. On noisy or changing HTML, models occasionally assign values to the wrong field with no error signal. At scale, that means rows of incorrect data that require validation logic to catch.

What actually works

The access layer requires real browser rendering, managed proxy infrastructure, and anti-bot handling that keeps pace with detection methods. Building and maintaining that yourself is a significant engineering investment. The alternative is using infrastructure that handles it for you.

The extraction layer requires consistency. If you need the same fields from thousands of structurally similar pages, a deterministic approach tied to the actual DOM position of each element is more reliable than a probabilistic one. The extracted value is always what is on the page, not an inference about what should be there.

This is the gap that Minexa.ai was built to close. It is a Chrome extension that handles JavaScript rendering, CAPTCHA, anti-bot protection, and geo-targeted content automatically. You navigate to a page, select the HTML container holding the data you want, and Minexa creates a reusable scraper. All data fields within that container are discovered automatically. No selectors, no schema definition, no library setup.

That scraper can then run across thousands of structurally similar pages. Train it once on a product page, a job listing, or a directory entry, and the same extraction logic applies at scale. If a field is missing on a given page, the output returns null rather than a fabricated value. If the page structure changes substantially, the scraper signals the mismatch explicitly instead of returning silent garbage.

The real cost of the DIY path

Building your own proxy rotation, managing browser fingerprinting, writing selector maintenance logic, and handling pagination across different site structures is not a weekend project. It is an ongoing engineering commitment. Every time a target site updates its layout or tightens its bot detection, something in your pipeline breaks.

For developers who want real-world data for projects without a dedicated data engineering budget, the DIY path has a high and recurring cost. The scraping is not dead. The assumption that it should be cheap and low-effort to maintain is what has not aged well.

If you are collecting course reviews, pricing data, job listings, or any structured content from sites without a usable API, the infrastructure problem is already solved. The remaining question is how much time you want to spend on selector maintenance versus actually using the data.
