# Performance guidelines

In order to provide the best possible LINE MINI App experience to your users, please take the performance of LINE MINI App into consideration.

A good reference regarding the importance of HTML5 performance, Why Performance Matters (opens new window), can be found on the Google Developers site.

For measuring performance, we recommend using performance measurement tools such as Lighthouse (opens new window) and Measure (opens new window), provided by Google.

LINE recommends the following score.

Performance measurement tool Score
Lighthouse (opens new window) Performance: 50 and above
Note
  • Please measure without executing LINE Login. When LINE Login is executed simultaneously, the performance of the LINE Login page is measured, preventing LINE MINI App's performance from being measured.
  • Be sure to measure in the production environment (real environment). Please note that the network environment can affect the performance score.
