To ensure an app is sustainable for long-term use, you should first review the app update history on its Salesforce AppExchange listing. Look for apps that are regularly updated, as this indicates active development and ongoing support. Check if the app is updated frequently to stay compatible with Salesforce’s seasonal releases, ensuring it remains functional as Salesforce evolves. Reading the release notes will give you an idea of how often new features are introduced or bugs are fixed. You should also check the app vendor’s reputation by reviewing customer feedback and ratings. Vendors who offer robust customer support, clear communication, and prompt issue resolution tend to maintain their apps over the long term, ensuring your business won’t face disruptions due to outdated software.
