Run your existing suite of tests on every update to avoid regression errors.
Avoid Dependency Decay
Software projects are cheaper to maintain if you keep them regularly up-to-date, and at a schedule of your choosing. Waiting reactively for a problem first and then trying to upgrade everything under time pressure is both inefficient and risky.
Unopinionated, flexible configuration.
The only opinion that matters when it comes to development tools is yours. Although Renovate's intelligent defaults suit most people, all features are configurable so there's a setup to suit everybody.
Initially, you receive an onboarding Pull Request with an analysis of your repository and an upgrade plan. Next, you can interactively reconfigure settings until the description matches what you want. Finally, merge the config once you're ready to start.
