(1) dashboard (https://dashboard.reflex.run) - A dashboard with tables and graphs
(2) chat (https://chat.reflex.run) - A ChatGPT clone

Use any Reflex app on Github as an initial template

reflex init now also supports passing in any Github url as a template. Currently the Reflex app must be in the root of the Github directory (meaning the rxconfig.py should be in the root.

reflex run will automatically init the app when required

Previously when updating versions of Reflex or cloning an existing Reflex app, you would have to run reflex init before you can reflex run. From 0.4.7, reflex init is only required the very first time you create an app. If you are missing a .web folder or there's a new version of Reflex, reflex run and reflex export will automatically init the app for you.
