Hosted apps and a stronger preview foundation

Build hosted apps with integrated sign-in, keep their source in Git, and see more reliable preview status.

A home for hosted apps

Flex now supports hosted app previews built on the VibeCore starter, with single sign-on integrated into the app experience. It gives teams a starting point for building internal tools that people can open through Flex.

The starter brings the app and its sign-in flow together, so you can spend more of the first iteration on the tool itself.

Keep the source behind your prototype

Hosted app prototypes now have Git-backed source managed by Flex. Work has a repository behind it from the start, giving subsequent iterations a shared source to build on.

Know when a preview is ready

We fixed a missing preview-ready message. When a preview finishes starting, its status can now reach the interface correctly, making it clearer when the app is ready to open.
