What is Openindex bringing to Data Expo Utrecht?

At Data Expo Utrecht 2026, Openindex is showcasing our full suite of data solutions, including web crawling, data extraction, and advanced search technology. We are bringing hands-on demonstrations and real conversations about how organizations can collect, index, and use data more effectively. Read on to find out exactly what we have in store and why it is worth stopping by our stand.

What solutions is Openindex showcasing at Data Expo Utrecht?

At Data Expo Utrecht 2026, we are presenting our core product range: Crawling as a Service, Data as a Service, and our site search technology. These solutions are designed to help organizations collect large volumes of structured and unstructured data, index it efficiently, and make it searchable in real time without heavy in-house infrastructure.

Our demonstrations at the expo focus on three main areas. First, we show how our crawling infrastructure can handle millions of URLs at scale, delivering clean, structured data feeds directly into a client’s systems. Second, we walk visitors through our site search solution, which can be embedded into any website with a single line of JavaScript. Third, we present our API development capabilities, which allow organizations to integrate our data collection and indexing tools directly into their own applications.

For organizations working in e-commerce, real estate, finance, or market research, these tools address a very practical challenge: getting reliable, up-to-date data without building and maintaining complex technical infrastructure from scratch. Data Expo Utrecht gives us the chance to show these capabilities in action and have honest conversations about what they can do for specific use cases.

Who should visit the Openindex stand at Data Expo?

The Openindex stand at Data Expo Utrecht is most relevant for data engineers, product managers, and technical decision-makers at organizations that depend on large-scale data collection or need powerful search functionality. If your team regularly deals with challenges around data freshness, scraping at scale, or delivering relevant search results to users, our stand is worth a visit.

More specifically, the following types of professionals will find the most value in stopping by:

• E-commerce teams looking to monitor competitor pricing or aggregate product data from multiple sources
• Real estate platforms that need to collect and index property listings from across the web
• Government and public sector organizations building internal knowledge bases or intranet search systems
• Market research firms that rely on automated data extraction for trend analysis
• Development teams evaluating search infrastructure for new or existing applications

You do not need to be a technical expert to have a useful conversation at our stand. We work with both technical teams and business stakeholders, and we are happy to discuss practical use cases, compliance considerations, and integration approaches at whatever level of detail makes sense for you.

How does Openindex’s crawling-as-a-service work?

Crawling as a Service means we manage the entire web crawling process on your behalf and deliver only the data you need. Instead of building and maintaining your own crawling infrastructure, you define the data you want, and we handle the technical complexity of collecting, cleaning, and delivering it on a schedule that suits your operations.

The process works in a few straightforward stages. We configure a crawl based on your target sources, whether that is a set of competitor websites, a category of public data sources, or a specific domain. Our infrastructure then visits those sources at regular intervals, extracts the relevant data, and structures it according to your specifications. The output can be delivered as a data feed, pushed directly into your database, or made available via API.

This approach removes several common pain points. Crawling at scale requires managing IP rotation, handling rate limits, parsing varied HTML structures, and keeping up with changes in website layouts. These are engineering challenges that take significant time and expertise to solve well. By outsourcing this to us, your team can focus on using the data rather than collecting it.

Compliance is also built into our approach. We follow ethical data collection practices and help clients understand the boundaries of what can be collected legally under GDPR and other relevant regulations.

What open source technologies power Openindex’s search solutions?

Openindex’s search and crawling solutions are built on a foundation of proven open source technologies, primarily Apache Solr and Lucene, Elasticsearch, and Apache Nutch with Hadoop. These tools form the backbone of our indexing, search relevance, and large-scale data processing capabilities.

Apache Solr, Lucene, and Elasticsearch

Apache Solr and its underlying library, Lucene, are among the most widely used open source search platforms in the world. They power full-text search, faceted filtering, and relevance ranking at enterprise scale. Elasticsearch offers similar capabilities with a strong focus on distributed search and real-time data indexing. We have deep expertise in both, which allows us to recommend and implement the right tool depending on a client’s specific requirements around performance, data volume, and query complexity.

Apache Nutch and Hadoop

Apache Nutch is an open source web crawler that integrates naturally with Hadoop for distributed processing of large datasets. This combination allows us to crawl and process millions of pages efficiently, making it particularly well suited to clients who need comprehensive and regularly refreshed data at scale. Our team has worked with these technologies since the early days of Openindex, giving us a level of hands-on experience that goes well beyond standard implementations.

Our commitment to open source is not just a technical preference. It means our clients benefit from community-tested, transparent, and extensible software rather than proprietary black boxes. It also means we can contribute improvements back to the ecosystem and stay closely aligned with how these technologies evolve.

What is Data Expo Utrecht and why does it matter for data professionals?

Data Expo Utrecht is one of the Netherlands’ leading events focused on data management, analytics, and data-driven technology. It brings together data professionals, technology vendors, and business leaders to explore the latest developments in data infrastructure, governance, and application. For anyone working in a data-intensive field, it is one of the most practical events on the Dutch conference calendar.

The expo matters for several reasons. It concentrates a high density of relevant expertise and product demonstrations in one place, making it far more efficient than researching vendors and solutions independently. Attendees can compare approaches side by side, ask direct questions, and see live demonstrations of tools that might take weeks to evaluate otherwise.

For data professionals specifically, events like Data Expo Utrecht serve as a useful checkpoint on the state of the industry. Conversations on the floor often surface challenges and solutions that are not yet widely documented, and the informal exchange between practitioners is frequently as valuable as the formal sessions.

For organizations evaluating new data tools or partners, the expo is a low-friction way to meet the people behind the products and assess whether there is a genuine fit before investing time in a formal procurement process.
