Android Feature Flag Cleanup Bot (GitLab + LaunchDarkly)
Android Feature Flag Cleanup Bot (GitLab + LaunchDarkly) This n8n automation detects unused (“dead”) feature flags in an Android Kotlin/Java codebase by comparing your GitLab repository code against LaunchDarkly’s feature flag list. It logs results in Google Sheets, creates Jira tickets for cleanup and sends Slack alerts automatically. Who’s it for Android engineering teams using Kotlin/Java. Teams managing feature flags in LaunchDarkly. DevOps/QA teams wanting to reduce technical debt from stale flags. How it works Weekly Trigger runs the process. GitLab Node fetches repository code. Regex Extraction finds all feature flags in code. LaunchDarkly API retrieves all configured flags. Comparison Logic marks flags as “dead” if unused in code and archived or off in production. Google Sheets stores flagged results. Jira creates a ticket for each dead flag. Slack notifies the team. How to set up Import JSON into n8n. Connect credentials for: GitLab OAuth2 Google Sheets Jira Slack webhook URL Update: GitLab repo details in the GitLab node. LaunchDarkly API key in HTTP Request node.

Adjust dead flag logic in “Find dead flags” node (e.g., treat test env separately). Modify Slack message to include more details (e.g., description from LaunchDarkly). Add email notifications for broader distribution. Add-ons Email Alerts** via Gmail/SMTP. GitHub / GitLab MR** to remove dead flags automatically. Confluence Integration** to document flag cleanup history. Use Case Examples Weekly automated cleanup alerts for large engineering teams. Maintaining clean feature flag lists in high-traffic apps. Compliance-driven projects requiring flag lifecycle tracking.
