Vistula builds, runs and maintains crawlers for the public sources you name, and hands you structured data instead of scraping headaches.
What's included
- Source review: each target site is checked for robots.txt rules, terms of use and personal-data risk before any crawling starts
- Crawler build and a pilot extract from one source within the first week
- Scheduled collection (hourly, daily or weekly) with schema validation and change detection
- Monitoring of every crawler, with breakages fixed within one business day
- Access to Vistula's archive of past crawls for common retail and travel sources, back to 2018
How buyers use it
- Competitor price and promotion tracking across online retailers
- Collecting product catalogues, specifications and availability for assortment analysis
- Monitoring job, property or car listings as market indicators
- Building training or evaluation sets from openly licensed web content
Coverage and methodology
Vistula collects only publicly accessible pages. It does not log in, bypass paywalls, solve CAPTCHAs or use fake accounts, and it stops a source if the site owner objects. Personal data is excluded by default; if a target page contains it, fields are dropped or hashed before storage. Every record carries the source URL, crawl timestamp and parser version, so you can audit where each value came from. Data is delivered to your cloud storage or warehouse in the schema agreed at kickoff.
