When you need to extract data like prices and trends from popular websites, AI scrapers let you do that without having to deal with broken parsers or proxy management. Instead of writing manual CSS selectors and maintaining infrastructure, you just describe the data you want and get back structured JSON.
Choosing the right scraper depends on what you need. For example, if you’re a developer, HasData’s API delivers reliable JSON output. If you prefer no-code, Browse AI handles simple visual scraping. Tools without an AI-extraction layer are a different comparison.
Top AI Web Scrapers
The tools below run from schema-driven APIs to browser extensions, and each entry covers how the tool extracts, what it costs on a stated credit base, and the work it suits.
1. HasData
HasData provides a web scraping API that keeps the fetching infrastructure on the service side.
The core of HasData’s AI is aiExtractRules, which allows you to define a JSON schema directly within the API call. Instead of using CSS selectors, you just specify the data fields, and the AI model parses the page to return clean, structured JSON.
You don’t need to be an experienced developer to use HasData’s API. The extraction rules are written in plain JSON, and ChatGPT writes them for you from one prompt. For example:
Based on the HasData Web Scraping API LLM Extraction documentation, write a JSON schema for aiExtractRules for this page: https://b2bdemoexperience.myshopify.com/collections/furniture. Extract the following product fields and infer the correct data type for each: name, url, price. Return only valid JSON.

Example request:
curl --request POST \
--url https://api.hasdata.com/scrape/web \
--header 'Content-Type: application/json' \
--header 'x-api-key: YOUR-API-KEY' \
--data '{"url":"https://b2bdemoexperience.myshopify.com/collections/furniture","proxyType":"datacenter","proxyCountry":"US","screenshot":false,"jsRendering":false,"aiExtractRules":{"products":{"type":"list","description":"List of products on the furniture collection page","output":{"name":{"type":"string","description":"Product name as displayed on the product card"},"url":{"type":"string","description":"Absolute URL to the product detail page"},"price":{"type":"number","description":"Price value as a number"}}}}}'Example output:
// Truncated for brevity
{
"products": [
{
"name": "Bluff Nightstand",
"url": "https://b2bdemoexperience.myshopify.com/products/bluff-oval-nightstand",
"price": 399
},
{
"name": "Butte Coffee Table",
"url": "https://b2bdemoexperience.myshopify.com/products/butte-coffee-table",
"price": 1099
},
{
"name": "Canyon Bed Frame",
"url": "https://b2bdemoexperience.myshopify.com/products/canyon-bed-frame-with-footboard",
"price": 2900
}
]
}Before analysis, we clean the document by removing inline scripts, SVG icons, base64 blobs, and heavy styling tags. This reduces the amount of junk the LLM must process, keeping the input lean and content-focused while lowering the risk of hallucinations.
Pros:
- Schema-driven extraction returns clean, predictable JSON in exactly the structure you define.
- The AI adapts to layout changes, so there are no selectors to keep updating.
- Scraping infrastructure and AI parsing come combined in one API.
- Output formats drop into data pipelines cleanly, RAG systems included.
- The API is built to handle millions of pages, with auto-retry logic.
- The proxy pool, browser rendering, and rotating exits run on the service side.
Cons:
- The interface is an API, with no visual point-and-click layer.
Pricing: Free plan with 1,000 credits. Paid plans start at $59/month for 200,000 credits, or $49/month with the year paid up front. An aiExtractRules request costs 10 credits, which is approximately $2.95 per 1,000 extractions on that plan month to month, and $2.46 on annual billing.
Best for: Enterprise teams and developers who need clean, structured JSON and precise control over data extraction for production systems.
2. Crawl4AI
Crawl4AI is an open-source Python library for building AI-ready crawlers. It uses Playwright for JavaScript rendering and can extract structured data with LLMs or CSS/XPath. It’s a library, not a managed service, so you’re responsible for the entire environment, including dependencies, proxies, and LLM API costs.
To extract data, configure an LLMExtractionStrategy with your LLM provider and an instruction, then run the crawler.
Example setup:
# Define the extraction strategy
llm_strategy = LLMExtractionStrategy(
llm_config=LLMConfig(provider="openai/gpt-4o-mini", api_token="..."),
instruction="Extract a list of 'products' with 'name', 'URL', and numeric 'price'"
)
# Run the crawler
result = await crawler.arun(
url="https://b2bdemoexperience.myshopify.com/collections/furniture",
config=CrawlerRunConfig(extraction_strategy=llm_strategy)
)Example output: Names and prices come back as displayed. The URL field is where it slips.
// Truncated for brevity
[
{
"name": "Grove Side Table",
"URL": "https://b2bdemoexperience.myshopify.com/products/grove-side-table",
"price": 349
},
{
"name": "Canyon Bed Frame",
"URL": "https://b2bdemoexperience.myshopify.com/products/canyon-bed-frame",
"price": 2900
}
]The second URL is invented. canyon-bed-frame returns a 404, and the page that exists is canyon-bed-frame-with-footboard, whose href was in the text the model read.
Pros:
- Open source, so you own the whole stack and can tailor the scraping process with no vendor lock-in.
- Advanced options manage sessions, hooks, and crawling strategies.
Cons:
- Setup and maintenance are yours, anti-bot updates included.
- The real cost includes developer time, servers, proxies, and third-party LLM API calls.
- Prompt-based extraction reads the product title and writes the URL from it instead of copying the
href, which is the failure the route test below isolates.
Pricing: The library is free. Infrastructure and API costs, however, are your responsibility.
Best for: Developers who need maximum control to build a custom solution and are prepared to manage the infrastructure and to validate fields the model can guess at.
3. Scrapy-LLM
Scrapy-LLM is open-source middleware that integrates LLMs into the Scrapy framework. It’s an extension for developers already building spiders with Scrapy, not a standalone tool. It intercepts scraped HTML and sends it to an LLM for data extraction based on a predefined schema.
To use it, define your desired data structure with Pydantic models, which serve as a guide for the LLM’s output.
Example schema definition:
from pydantic import BaseModel, Field
from typing import List, Optional
class Product(BaseModel):
name: str = Field(description="Product name")
url: str = Field(description="Absolute URL to the product page")
price: float = Field(description="Price as a number")
class ProductCollection(BaseModel):
products: Optional[List[Product]] = Field(description="List of products")Example output: The middleware produces JSON matching this structure, prices included. The Pydantic model pins the types and leaves the values to the LLM, which shows in the first record.
// Truncated for brevity
{
"products": [
{
"name": "Bluff Nightstand",
"url": "https://b2bdemoexperience.myshopify.com/products/bluff-nightstand",
"price": 399
},
{
"name": "Butte Coffee Table",
"url": "https://b2bdemoexperience.myshopify.com/products/butte-coffee-table",
"price": 1099
}
]
}The real product page is /products/bluff-oval-nightstand, which is what the schema-driven run returned from the same page. The model wrote the title out as a slug instead, and that address returns a 404. Nothing in the response marks it, and the rest of the pipeline follows it anyway.
Pros:
- It fits directly into existing Scrapy workflows.
- Pydantic models define the data structure.
- The middleware is open source and open to customization.
Cons:
- It’s only useful inside Scrapy, and it inherits that framework’s setup and deployment complexity.
- A Pydantic model fixes the field types and not the values, so product URLs still arrive as slugified titles.
Pricing: The middleware is free, but costs depend on the LLM provider and your infrastructure.
Best for: Teams who are already using Scrapy and want to experiment with AI-based parsing, but not for production systems, where data accuracy is critical.
4. Parsera
Parsera is an AI parsing tool that extracts structured JSON from a URL. It operates as a standalone service or as an “Actor” on the Apify Store, which allows for scheduling, proxy use, and data storage within the Apify platform. Parsera infers the data structure automatically.

Pros:
- It infers what to extract, with no CSS selectors to write.
- Extraction stays simple on simple to moderately complex pages.
Cons:
- Full features require the Apify platform.
- Cost per extraction runs higher than API-based alternatives at scale.
Pricing: Free plan with 100 credits. The Professional plan is $29/month for 3,500 credits, and an extraction costs 5 credits, which puts 1,000 extractions at about $41 on that plan. Pay-as-you-go credits top up at $10 per 1,000.
Best for: Users with low-volume needs or those already in the Apify ecosystem.
5. Bardeen.AI
Bardeen.AI is an AI automation agent in a Chrome extension, designed for go-to-market teams. Web scraping is one of its features, allowing users to build “Playbooks” to scrape data and send it to applications like Google Sheets or a CRM.

Pros:
- In-browser automation covers tasks like saving LinkedIn profiles.
- It connects with hundreds of popular applications.
- A library of playbook templates covers common tasks.
Cons:
- It runs in the browser, automating actions rather than feeding a backend pipeline in bulk.
- Pricing is optimized for workflows rather than data volume.
Pricing: Free plan with 100 credits/month. Paid plans start at $10/month (Basic) with Premium at $50/month for 1,000 monthly credits. A scraped row costs 1 credit, and enrichment rows cost 3.
Best for: Sales and marketing professionals automating repetitive tasks and light data collection in their browsers.
6. ScrapeGraphAI
ScrapeGraphAI uses natural language prompts to extract structured data. It’s available as an open-source Python library and a premium API. The idea is that you simply tell the tool what you want in plain English (e.g., “Extract the name, price, and URL for each product”). In our tests, though, it failed to extract product prices, even after multiple attempts.

Pros:
- Natural language prompts make it fast to start.
- It comes as both an open-source library and a managed API.
- It handles unstructured content like articles and descriptions well.
Cons:
- A prompt constrains the output shape and not the values it draws on, so a field the model can guess from the page text is a field it may guess wrong.
- High-volume scraping costs more per request here.
- The free library leaves LLM keys and infrastructure to you.
Pricing: Free grant of 500 one-time credits. The Starter plan is $20/month for 10,000 credits, and a request costs 1 to 6 credits depending on the render mode, which puts 1,000 extractions between $2 and $12.
Best for: Users who prioritize a natural language interface for quick, small-scale tasks.
7. Browse AI
Browse AI is a no-code tool designed for non-technical users. You train a “robot” by clicking on the data you want, and it learns to repeat the process.

Pros:
- The visual interface needs no programming at all.
- Robots run on a schedule and send change notifications.
- It connects with over 7,000 applications through Zapier and Make.
Cons:
- It’s browser-based and unsuited to server-side pipelines.
- Mimicking user actions is slower than a direct API call.
- Row-based pricing gets costly on large tables.
Pricing: Personal is $19/month billed annually (12,000 credits upfront for the year) or $48 month-to-month with 2,000 monthly credits. Extraction is row-based, and a 50-row page costs 5 credits.
Best for: Non-technical users automating targeted, low-volume data extraction.
8. Firecrawl
Firecrawl is an open-source crawling and scraping engine with a managed API, built around LLM-ready output. A page comes back as clean markdown, and the JSON format extracts structured data to your prompt or schema instead. It came up in AI answers more often than anything else in this category when we looked. The one-page test above didn’t include it, so the accuracy numbers there say nothing about Firecrawl either way, and what follows is what its documentation specifies.
Pros:
- It’s open source with a managed API on top, so the exit path exists in both directions.
- Credits are shared across all endpoints, and the JSON extraction is a per-page format flag rather than a separate product.
- Markdown output is ready for RAG pipelines without cleanup.
Cons:
- The JSON format adds 4 credits per page on top of the 1-credit scrape, a fivefold jump for structured output.
- Extraction accuracy on precise fields is unmeasured here.
Pricing: Free plan with 1,000 credits/month. Hobby is $19/month ($16 billed annually) for 5,000 monthly credits. A basic scrape costs 1 credit and the JSON format adds 4, so an extraction page costs 5 credits, about $19 per 1,000 extractions on Hobby and $4.15 on the $83 Standard plan.
Best for: Developers feeding LLM pipelines who want managed crawling with markdown or structured output.
9. Thunderbit
Thunderbit is an AI web scraper in a Chrome extension aimed at non-technical users. The flow is two clicks, AI Suggest Fields and then Scrape, with subpage scraping and scheduled runs on top. The one-page test didn’t cover it either, so the facts below come from its own documentation.
Pros:
- The two-click flow works without any programming.
- It follows subpages and pagination on its own.
- Scrapes run on a schedule from the browser.
Cons:
- It’s a browser extension, and a server-side pipeline is out of its scope.
- A page can cost up to 30 credits depending on the extraction, so budgets are hard to predict.
- Extraction accuracy is unmeasured here.
Pricing: The free tier covers 6 pages/month. Starter is $15/month month-to-month, or $9/month with the year paid up front for 5,000 credits a year. Pro runs $38/month, or $16.5/month yearly on a promo against a $24 list price, for 30,000 credits a year. A page costs up to 30 credits.
Best for: Non-technical users who want AI-suggested extraction inside the browser with light volumes.
Ten Runs on the Same Page
Every tool above points at the same furniture collection, 17 products with a title, a link and a price on each card. Ten runs separate a one-off model slip from something that repeats.
This measures the three routes rather than nine products, because the tools above reduce to three ways of getting a value out of a page. Schema-driven extraction through the HasData API runs aiExtractRules against the parsed DOM. Gemini 2.5 Flash, handed the page as text with a JSON schema attached, matches how scrapy-llm and Parsera constrain a general model. The same model on the same text with a prompt and no schema matches how Crawl4AI and ScrapeGraphAI ask for the same data. Each tool wraps its own prompt and its own provider around that, so a specific product can land above or below its route, and ScrapeGraphAI returning no price at all on this page is one example. Ten runs per route, 170 product rows each, scored field by field against the store’s own products.json.
| Route | Title wrong | Price wrong | URL wrong | Products missed |
|---|---|---|---|---|
| Schema against the DOM | 0 / 170 | 0 / 170 | 0 / 170 | 0 |
| Schema against page text | 0 / 170 | 0 / 170 | 30 / 170 | 0 |
| Prompt against page text | 0 / 170 | 0 / 170 | 30 / 170 | 0 |
Prices came back right on all 170 rows of every route, and so did titles. A general model reading the page text can read a price off it. Every error is in one field.
Three of the 17 products lost their URL, the same three in all ten runs of both text routes. Their handle and their card title disagree:
| Card title | What came back | The page that exists |
|---|---|---|
| Bluff Nightstand | /products/bluff-nightstand | /products/bluff-oval-nightstand |
| Canyon Bed Frame | /products/canyon-bed-frame | /products/canyon-bed-frame-with-footboard |
| Horizon Bed with Footboard | /products/horizon-bed-with-footboard | /products/horizon-bed-frame-with-footboard |
All three return 404. The correct href sat in the text handed to the model, next to the title it belonged to, and the model wrote a slug from the title anyway. Attaching a JSON schema didn’t change it. The same 30 rows failed.
A wrong price trips a sanity check on the way in. A wrong URL is a well-formed string that looks fine in the database and breaks whatever fetches it next, and the run that read the href off the DOM never produced one. Firecrawl and Thunderbit are outside these numbers, so their entries in the table below carry no accuracy figure.
Side-by-Side Comparison of AI Web Scrapers
The verified numbers side by side, with the basis every derived figure comes from:
| Tool | Best For | AI Extraction Method | Entry plan | Credit base of the entry plan | Per 1,000 extractions |
|---|---|---|---|---|---|
| HasData | Developers and enterprise | Schema-driven rules | $59/month ($49 billed annually) | 200,000 credits, 10 per extraction | $2.95 |
| Crawl4AI | Open-source developers | Schema-driven / prompts | Free | your infrastructure, your LLM tokens | depends on the LLM provider |
| Scrapy-LLM | Scrapy developers | Pydantic schema | Free | your infrastructure, your LLM tokens | depends on the LLM provider |
| Parsera | Low-volume automation | Automatic inference | $29/month | 3,500 credits, 5 per extraction | $41 |
| Bardeen.AI | Sales and marketing | Point-and-click / prompts | $10/month | 100 credits/month, 1 per row | row-based |
| ScrapeGraphAI | Prompt-based scraping | Natural language | $20/month | 10,000 credits, 1-6 per request | $2-12 by render mode |
| Browse AI | Non-technical users | Point-and-click | $48/month ($19 billed annually) | 2,000 credits/month, about 1 per 10 rows | row-based |
| Firecrawl | LLM pipelines | Prompt or schema (JSON format) | $19/month ($16 annually) | 5,000 credits/month, 5 per extraction page | $19 |
| Thunderbit | Browser users, light volumes | Two-click AI suggestions | $15/month ($9 billed yearly) | 5,000 credits/year, up to 30 per page | page-based, varies |
The per-1,000 column names the credit base it came from, so swapping in your own page count moves the figure with it. Row-based tools are the exception, since their cost follows how many rows a page yields rather than how many pages you scrape.
Conclusion
The split showed up on the same demo page over ten runs each. Routes that hand the page to a general-purpose model as text got every title and price right and turned three of the 17 product URLs into 404s, every run, with and without a JSON schema. Extraction against the parsed DOM returned all 170 rows intact.
Some tools constrain the model with a schema, others trust a prompt, and that is the difference to choose on. The prompt-only routes cost three product URLs in seventeen on every run here, and a schema catches exactly that. The table’s Best For column covers which shape suits which team.
For a production system, pick the schema-driven route and check the cost basis in the table against your own volumes. On our test page that route returned correct data at $2.95 per 1,000 extractions on HasData’s entry plan.
