Expert guides on automated cleanup, technical debt reduction, and flag lifecycle best practices
I ran FlagShark on the open source repos of Unleash, PostHog, and GrowthBook. The companies building feature flag tools have stale flags in their own codebases.
A step-by-step guide to migrating between feature flag platforms—from LaunchDarkly to alternatives, from custom implementations to managed platforms, and using the migration as a flag debt cleanup opportunity.
Feature flag best practices depend on team size and scale. Learn the right strategy for small teams under 20 engineers and large organizations with 100+ engineers, including common mistakes at each stage.
Stop fighting for debt time in every sprint. This playbook covers the 20% rule, RIVER-based sprint selection, stakeholder buy-in strategies, and what a successful debt reduction sprint actually looks like.
Calculate the real cost of technical debt and build a CFO-friendly business case for debt reduction. Includes formulas, templates, and concrete ROI examples for feature flag cleanup.
