🤖 Overview

Eventware is a web crawler operated by Eventware GmbH, a German company specializing in event management and calendar aggregation, first documented in official developer documentation at https://www.eventware.de/en/bot. Its primary purpose is to collect publicly available event listings, dates, locations, and metadata from websites to populate the Eventware event database and calendar platform used by publishers and event organizers.

🌐 Technical Behavior

The Eventware crawler employs a breadth-first crawl strategy, typically starting from known event listing pages and following links to detail pages, with a maximum crawl depth of three levels per domain. It sends requests at an average rate of one request every 5–10 seconds, with bursts of up to 10 requests per minute during initial scans, and uses HTTP/1.1 with persistent connections. IP ranges allocated to the crawler are documented in the Eventware DNS PTR records (e.g., 5.45.96.0/20, 185.150.128.0/18) and are published in the official bot documentation. The crawler respects standard HTTP protocols, including Accept-Encoding: gzip and Accept-Language headers, and does not execute JavaScript or parse embedded media unless explicitly required for event detail extraction.

📋 robots.txt Compliance

According to the Eventware Bot Policy page (https://www.eventware.de/en/bot/robots), the crawler fully honors Disallow directives in robots.txt and will also obey Crawl-Delay directives with a minimum delay of 5 seconds if specified. It does not override explicit disallowances and provides a dedicated feedback form for site owners to report non-compliance issues.

🔍 Detection Indicators

The primary User-Agent string is Eventware/1.0 (+https://www.eventware.de/en/bot), with a secondary variant EventwareBot/2.0 used for deprecated endpoints. Behavioral fingerprints include consistent request order (list pages before detail pages) and a custom HTTP header X-Eventware-Crawler: 1 present on all requests. Additionally, the crawler always resolves reverse DNS records to hostnames matching *.eventware.de.

📊 Data Usage

Collected data—event titles, descriptions, dates, times, venues, categories, and contact information—is aggregated into the Eventware central database for use in calendar feeds, searchable event lists, and partner publisher websites. Eventware does not use crawled data for AI model training or analytics beyond event indexation, as stated in their privacy policy (https://www.eventware.de/en/privacy).

⚙️ Rate Limiting Policy

The Eventware bot is rate-limited because its structured, targeted crawling can generate moderate request bursts that may impact server performance on shared hosting environments; threshold-based blocking (e.g., limiting to 30 requests per minute) is implemented to ensure fair resource usage without blocking legitimate indexing.
