YandexTracker
YandexTracker is not a web crawler but a project management and issue tracking system from the Russian technology company Yandex. Its user-agent appears in server logs as a result of API integrations between a company's internal systems and the YandexTracker platform, not because of web crawling. This traffic is part of an authorized and deliberate integration for workflow automation.
What is YandexTracker?
YandexTracker is a project management and issue tracking system from Yandex, similar to Jira or Asana. It is an API-based service, not a traditional web crawler. When YandexTracker appears in your logs, it is because of an API integration between your systems and its platform. The system identifies itself with user-agent strings like YandexTracker-API/<version>
. The service is designed for system-to-system communication, not web content discovery.
Why is YandexTracker crawling my site?
YandexTracker is not 'crawling' your site in the traditional sense. Its presence in your logs indicates that your systems have a deliberate integration with the Yandex project management platform, likely set up by your development team to synchronize tasks or issues. The frequency of connections depends on how the integration is configured. These connections are authorized and expected as they require valid API credentials to function.
What is the purpose of YandexTracker?
The purpose of YandexTracker is to serve as a comprehensive project management and issue tracking system. The API connections seen in your logs support these functions, allowing YandexTracker to integrate with other systems in your technology stack, such as a customer support platform. For website owners, these integrations can provide significant value by streamlining workflows and connecting different systems. Unexpected activity, however, could indicate a misconfiguration.
How do I block YandexTracker?
Blocking YandexTracker cannot be done effectively with robots.txt
because its interactions are via API calls, not web crawling. If you need to block this traffic, you would need to do so at the firewall or API gateway level. However, this would break any legitimate integrations your company has with the YandexTracker platform.
