Find the values your scraper got wrong.
With proof.
AI opens each row's page, reads it like a person would and fixes the wrong values. Every fix comes with a screenshot.
Free: unlimited data checks and 500 visual checks a month. No card needed.
Example fix: your value, the page and the correction.
More than 12 years in web scraping. Hundreds of clients before DeCrawl, including some of the largest e‑commerce and delivery companies.
Nothing broke. The data is still wrong.
Scrapers rarely fail with an error. A selector grabs the wrong element. A price loads after the page is read. Every row still looks valid, so nobody notices.

Visual check & fix
Choose the rows. AI opens each page, reads the values and fixes the wrong ones, with a screenshot as evidence.
We delete your file 30 days after upload. Reports and fixes stay.
It passes every rule.
It's still wrong.
Your tests, and our data checks, confirm that each value exists and looks right. Only a visual check against the page catches a product marked in_stock that shows Sold out.
Check every row, or start with a sample
Check all 500,000 rows against their pages, or start with 1,000 random rows to see how bad it is. You choose in the visual check. Each row is 1 visual check.
Any scraped data. No setup.
Products, listings, reviews, jobs or anything else. We detect the field types. You don't write rules or a schema.
Every wrong value comes with the evidence
Each one shows your value, the value on the page and a screenshot with it highlighted. Check any of them yourself, then download the fixed file.
Unlimited data checks. Pay only for visual checks.
Each row checked against its page is 1 visual check. Pages we can't open don't count.
Need more? Extra visual checks are $25 per 1,000 on any paid plan.
