Possible disadvantages

  Customer support is not always as responsive as some users would hope, which can lead to frustration when needing assistance.
• Lack of Subscription Options
  For users who prefer subscription plans with unlimited calling, KeepCalling primarily operates on a pay-as-you-go model.

  Since KeepCalling relies on internet connectivity, users might experience issues in areas with weak or unstable internet connections.

  The service generates high-fidelity PDF documents that accurately capture the design and functionality of the original HTML.

Possible disadvantages

• Cost
  Depending on your usage, HTML PDF API can become expensive, particularly for large-scale operations requiring high volume or premium features.
• Dependency on Internet Connectivity
  Being a cloud-based service, it requires a stable internet connection, which can be a limitation in environments with poor connectivity.
• Latency
  Network latency can affect the speed of PDF generation, which may impact time-sensitive applications.
• Rate Limiting
  Usage may be subject to rate limiting, potentially hindering the performance of high-demand applications or requiring additional cost to increase limits.
• Privacy Concerns
  Sensitive data needs to be transmitted to a third-party server for processing, which could raise privacy and compliance concerns depending on jurisdiction and data sensitivity.
• Potential Downtime
  As with any cloud-based service, there is a risk of downtime or service disruptions due to server issues or maintenance.
