As companies scale, their needs change, and they may outgrow in-house tools like feature flag management systems. Key indicators of needing a commercial solution include support for multiple programming languages, client-side vs. server-side flag evaluations, access control and permissions, advanced targeting rules, audit logs, integrations with existing tools, and an intuitive user interface. Additionally, scaling the infrastructure to support feature flagging on a larger scale can be costly. Companies should consider whether maintaining an in-house solution is worth their time and resources, as commercial solutions may offer more comprehensive features and allow teams to focus on core product development.
