Move global variables and configurations from your code repository into a dropconfig, and you can now update them without deploying your code.
As easy as vanilla ES6 pull:
Control how your application works using feature-flags stored in a dropconfig.
Roll back changes with a push of a button by re-publsihing an older version of the dropconfig. Even from your phone.
Store and manage translation-strings for your app in a dropconfig. Or several dropconfigs: one for each language.
Share a dropconfig with a translator for data-only editing. Be sure all the tokens remain unchanged and JSON is valid.
Is your app mostly static, but you want to display announcements? Or update the changelog? Or change the year in a copyright statement?
Instead of CMS, or Firebase - just use Dropconfig. Dropconfig can be your mini-CMS when real database is an overkill.
Do you have a batch-script and someone else runs it. May be it's Travis-CI, or cron-daemon.
Populate your environmental variables from a dropconfig:
Coding Arduino or Raspberry Pi?
If your device can make HTTP-requests, you can dynamically control it with Dropconfig.
