At Google I/O 2017, Google announced that the Instant Apps SDK is open to all developers. Thumbtack worked with Google before the conference, creating an instant app for our Android customer app. In the process we provided feedback and bug reports to Google around the SDK and supporting tooling.
In Google’s own words:
