Reasons to choose Web Scraper
Build it where the page is
Sitemaps are built in the free extension for Chrome, Firefox, or Edge, with the AI Sitemap Wizard or point and click, then synced to Cloud to run on a schedule.
Web Scraper extensionOne plan, one line item
Scraping, scheduling, datacenter proxies, the Parser, data quality checks, and delivery sit inside the Cloud plan, with no separate proxy or per-result bill to reconcile.
Web Scraper pricingVolume stops moving the invoice
The fee buys concurrent scraping capacity with unlimited URL credits, so a bigger crawl does not raise it, and retries of empty or failed pages cost nothing.

The two prices do not buy the same unit
Thunderbit bills a credit per extracted row, so a data-rich page costs more than a sparse one. Web Scraper charges for concurrent scraping capacity, with unlimited URL credits whatever the row count.
- The Thunderbit figure divides the monthly plan fee by its included credits, at one standard row per URL.
- Subpage scraping and enrichment consume more credits per row and are excluded from that figure.
- 1 Proxy traffic is sold separately, so the price is calculated based on a 250 KB page size.
For a small, occasional job that ends in a spreadsheet, an AI agent that proposes the columns gets there in a few clicks.
Switching from Thunderbit
Can a Thunderbit scraper be imported?
Scrapers move over as Web Scraper sitemaps built in the free browser extension, where the AI Sitemap Wizard maps listing pages for you. Many common targets also have a ready-made Marketplace sitemap that you can import into Web Scraper Cloud.
How does the bill change?
A row-metered credit balance is replaced by a capacity plan. The fee buys concurrent scrapers with unlimited URL credits, so the number of rows a page yields no longer changes the cost.
Do we lose the AI setup?
No. The AI Sitemap Wizard maps repeated listing data and detects pagination and infinite scrolling, and the Advanced Sitemap Builder is there when a target needs manual selector work.
How does data reach our systems?
Results are retrieved through the API or delivered to Google Sheets, Google Drive, Dropbox, Amazon S3, Google Cloud, or Microsoft Azure after each job. Webhook notifications report job status and identifiers.
