This feature is supported for both UI Kit and Custom UI across all environments, including production. It captures console.error, uncaught exceptions, and unhandled promise rejections.

App logs give you the information you need in order to debug your apps. Logs are enabled by default when a user installs your app, and are displayed in the developer console. If you need to view app logs for a site where the user has disabled log access, you can ask them to re-enable access.

For Isolated Cloud (IC), customers don't have the option to enable or disable log sharing access to developers in Admin Hub, and app developers can't access IC logs in the developer console. IC customers can still download the app logs from Admin Hub and share them with the developer. This is the only way for developers to get access to logs of an IC customer.

For Atlassian Government Cloud (AGC) or FedRAMP, customers can enable or disable log sharing access to developers in Admin Hub, with sharing enabled by default. For more information, see Access app logs.

To view app logs:

Access the developer console.
Select the Forge app that you want to view metrics for.
Select Logs in the left menu.

You'll see the following screen:

Log writes contribute to your app's billable usage. For advice on reducing log volume, see Avoid verbose logging in high-frequency functions.
