I recently spent a few months on a project where we used Django without a single HTTP / external endpoint. It basically consumes messages from a rabbitmq queue, then creates new celery tasks which are then run.

Using Django for this is of course completely overkill, but using a known framework, especially considering that Django is what's used in other applications here, did have some benefits. All our devs having to fix something in this app, will immediately be familiar with it as it looks exactly like the other Django apps we have. No new way to do migrations, talk to the db, open a shell, log- and reliability setup is identical with other apps, etc. etc.
