This is not entirely correct anymore. Drone can trigger builds and deployments using the API or the command line utility, and there is a PR to add to the user interface [1]. The caveat is you need to trigger from an existing build or commit, because Drone needs a commit sha to fetch the configuration from the repository.
There are individuals using Drone + cron to execute scheduled tasks such as security scans and nightly integration tests.
