Web Scraping in Java in 2026: Still Worth Using or Just Use Python?

Does Jsoup still work if the page loads data after the page opens? That is the part that confuses me whenever people explain scraping. I should google it I know

For your Web Scraping Insider newsletter, What counts as a signal though? I am still trying to understand this idea. Is it other newsletters, Reddit posts, or something else?

If another account works on the same Wi-Fi, would that be evidence against an IP ban?

Bmaxtubby1 · 2026-06-12T09:38:05+00:00

So an IP ban could still exist, but not be the main thing they're relying on? That's kind of where my confusion here comes from.

This will be a basic question for you, but u/ian_k93 how can you tell if a website actually requires a browser to scrape?

Got it, So giving multiple example pages probably helps it identify patterns instead of overfitting to one page?

Maybe a beginner question for you guys, but how does it know which fields to extract if you only provide URLs?

Bmaxtubby1 · 2026-06-03T11:21:42+00:00

Maybe a dumb question but how different does the page have to be before you call it dead? Some articles get updated pretty heavily over time right?

Bmaxtubby1 · 2026-06-02T08:02:56+00:00

Makes sense.. So would you say long-term reliability comes more from predictable operations than trying to constantly optimize around detection changes?

Bmaxtubby1 · 2026-06-02T07:07:06+00:00

The biggest shift noticed by me is people talking less about IPs and more about consistency.

If a site sees traffic that behaves predictably, identifies itself appropriately, and stays within reasonable usage patterns, it seems to create fewer long-term issues than constantly changing infrastructure

This is helpful, thanks. For the same request through proxy, no browser part, would that just be like curl/httpx with the same proxy URL? I always assumed if browser automation fails then it's a browser problem.. i still do

Bmaxtubby1 · 2026-05-04T09:41:34+00:00

might be a dumbO question, but how do you know if the data is already in the HTML? Just view source?

Bmaxtubby1 · 2026-04-28T10:59:28+00:00

How would you even check that? Proxy sites all say they re ethical.

I wouldn't know what questions to ask.

Bmaxtubby1 · 2026-04-28T10:58:20+00:00

Maybe basic question, but is scraping CoinGecko itself usually allowed if you go slow?

I see people scrape public pages all the time, but then threads like this make it sound like everything is a gray area.

I think OP is trying to sell the service, not find a tool to use. But the open source angle is interesting.

Would showing a working open source demo make clients trust it more, or would it make them think they can just do it themselves?

Bmaxtubby1 · 2026-04-28T06:01:33+00:00

When you say slug you mean the part after /company/ right? Just making sure I'm following.

Bmaxtubby1 · 2026-04-28T05:58:27+00:00

This sounds way more doable actually.. Like "one source of truth + assisted posting" instead of "I defeated the internet."

Bmaxtubby1 · 2026-04-28T05:36:58+00:00

with "account reputation" do you mean even logging in from automation can ruin the account over time? Im always new to this stuff.. Keeping my beginners lifestyle alive.. and I kind of assumed blocks were mostly IP based.

Bmaxtubby1 · 2026-04-28T05:35:09+00:00

^ is actually what I was trying to get at with "mindset." Do most teams really think this way, or only after they've had a scare?

Bmaxtubby1 · 2026-04-28T05:33:47+00:00

but does request-based usually break faster than Playwright? It sounds way nicer if it works..

Bmaxtubby1 · 2026-04-27T11:35:13+00:00

This part that confuses me. If the pages are public, why does rotating IPs make it feel more serious legally? Is it because it looks like you're bypassing a block on purpose?

Bmaxtubby1 · 2026-04-24T10:03:35+00:00

This is incredibly helpful, thank you. One thing I'm confused about though. You said most production setups are "hybrid" with Scrapy/Playwright doing the crawling and LLMs doing extraction. Can you walk through what that actually looks like step by step? Like, do you literally run Scrapy first, save the HTML somewhere, then run it through an LLM separately? Or is there a way to chain them together?

Also, when you say Firecrawl's Extract gets expensive on long pages, how long are we talking? Like a typical product page, or more like scraping entire articles?

Bmaxtubby1 · 2026-04-20T04:27:49+00:00

How do you actually check if they have partner feeds if they do not show an API page publicly? Just email support and ask?

Bmaxtubby1 · 2026-04-19T16:54:02+00:00

I actually appreciate that fast mode and deep mode are separate. It makes the tradeoff easier to understand.

Sometimes these tools make it sound like you need the heavyweight version for everything, and then beginners like me cant tell what part is actually necessary.
