Web Crawling and Scraping – Tailored Data Extraction

For many years, I’ve been deeply involved in web crawling and scraping and have developed a strong passion for it. I’m the creator of the open-source library crwlr.software and the SaaS platform crwl.io built on top of it.

I develop custom crawlers tailored to your requirements and deliver the exact data you need. If desired, your crawlers can run regularly and automatically to continuously supply your applications with up-to-date information. I’m also happy to support you with integrating the collected data into your systems or analyzing the raw data.

Custom crawlers

Just let me know which data you need from which sources (websites) – I’ll take care of the rest. Whether it’s job listings, news articles, real estate ads, or other publicly available content: I’ll create a crawler based on your requirements and deliver the data in your desired format – CSV/Excel, JSON, or anything else.

Regular updates

If desired, I can set up your crawlers in my own crawling service crwl.io. There, fixed execution times can be defined – from monthly to every few minutes. The crawlers then run automatically on crwl.io’s servers and provide continuously updated data.

Regular updates

If you use the crwl.io app to collect data on a regular basis, the gathered data can be seamlessly integrated into your existing systems via webhooks and a REST API. A webhook can notify your applications once a new crawler run is complete, and the API can then be used to access the fresh data. If needed, I’m happy to advise or assist you with the integration.

I don’t just help you collect the data – I can also support you in processing it. I can filter, restructure, refine the raw data and, if needed, generate reports or visual representations based on it.
