adAPT

The idea for Adapt came from a problem we experienced firsthand: our systems relied on legacy dependency versions that offered fewer features, weaker performance, and growing maintenance risk. Upgrading sounded straightforward, but our large codebase made it difficult. Every major migration required developers to inspect thousands of files, identify breaking changes, update APIs, resolve dependency conflicts, and repeatedly test the application. This consumed significant engineering time and made upgrades risky enough to postpone. Existing tools could notify us about new versions or apply isolated codemods, but they could not manage an entire migration safely. We wanted a tool that could answer:

• What will break?
• Which changes can be automated safely?
• Which changes require human judgment?
• Did the migration introduce new failures?
• What evidence proves the upgrade succeeded? This inspired Adapt, a CLI that treats dependency modernization as a structured engineering campaign rather than a version-number change.
