Possible disadvantages

• Complex Setup for Beginners
  The initial setup can be complex for those who are not familiar with headless browsers or visual testing concepts, potentially resulting in a steep learning curve.
• Performance Overhead
  Running visual tests can be resource-intensive, which might affect performance, especially with a large number of scenarios and comparisons.
• Maintenance Effort
  Creating and maintaining test scenarios can require ongoing effort as the application evolves, including updating baselines and handling false positives.
• Limited to Visual Testing
  BackstopJS focuses solely on visual regression testing and doesn't provide broader testing capabilities like functionality or performance testing, necessitating additional tools for comprehensive test coverage.
• Screenshot Differences
  Slight, acceptable differences in rendering between test runs can lead to false positives, requiring fine-tuning and adjustments for threshold settings.

• User-Generated Data
  Numbeo relies on contributions from users around the world, providing a diverse and broad range of data on cost of living in many locations.
• Wide Coverage
  The platform covers numerous countries and cities worldwide, making it useful for global comparisons of cost of living metrics.
• Regular Updates
  Numbeo is frequently updated with new data, reflecting recent changes in living costs which can be beneficial for up-to-date information.
• Comprehensive Categories
  Includes a wide array of cost categories such as housing, food, transportation, and utilities, helping users get a detailed view of living expenses.
• User-Friendly Interface
  The website's interface is designed to be intuitive and easy to navigate, making it accessible for users seeking information quickly.

Possible disadvantages

• Data Quality Variability
  Since the data is user-generated, the accuracy and reliability might vary based on the number and expertise of contributors in each area.
• Potential for Outdated Information
  In locations where fewer users contribute data, the information might not be updated as regularly, leading to potential outdated data.
• Lack of Verification
  Numbeo lacks a formal verification process for the data submitted, which can raise questions about the credibility of the information provided.
• Sample Size Limitations
  Smaller cities or less popular locations might have limited data due to fewer contributors, affecting the robustness of comparisons in these areas.
• Possible Bias
  The data may be biased towards the experiences and spending habits of those who contribute, which might not represent all demographics accurately.
