• Security Concerns
  Rendering content on the client side may expose sensitive information within the page during the rendering process, posing security risks if not handled carefully.
• Lack of Dynamic Content Handling
  Dynamic content like videos, animations, or elements with JavaScript-based changes during rendering might not be accurately captured.

• Limited Offline Capabilities
  As a cloud-based platform, OctoPerf’s functionalities are largely dependent on internet connectivity, which may not be ideal for all user scenarios or regions with unreliable internet.
• Resource-Intensive
  Running extensive load tests can be resource-intensive, potentially affecting the performance of other operations within an organization.
• Customization Constraints
