+## Testimonies from extension authors
+
+Several packages authors in the Dart and Flutter ecosystem have built their own DevTools
+extensions to provide their users with a great developer experience.
+
+* "DevTools extensions are a neat way to save hours of debugging by showing information
+that would be otherwise difficult to obtain." - Remi Rousselet,
+[package:provider](https://pub.dev/packages/provider)
+
+* "By allowing developers to inspect databases and find potential issues in the familiar
+DevTools environment, Drift's DevTools extension saves users a lot of time and makes the
+package easier to use. Writing the extension was straightforward, and I think even simple
+extensions can help users a lot." - Simon Binder, [package:drift](https://pub.dev/packages/drift)
+
+* "Our DevTools extension allows Serverpod to make our developer tooling available for more
+platforms and with better integration with the Dart ecosystem. Having the tools bundled with
+our Serverpod package is a huge benefit, as our users won't have to install any additional
+applications." - Viktor Lidholt, [package:serverpod](https://pub.dev/packages/serverpod)
+
+* "Thanks to DevTools extensions we could develop a separate inspector tab for interacting
+with native platform views (such as a native Android button). It allowed our Patrol users
+to explore native view hierarchies without installing any additional tooling - distributed
+within the Patrol package itself." - Mateusz Wojtczak & the Patrol
+team, [package:patrol](https://pub.dev/packages/patrol)
