Self-Hosted Task Scheduling System (Back End and UI and Python SDK)
The dashboard exposes cron/interval scheduling, timezone support, retries, execution history, realtime metrics and API-key login, and it runs with a single docker-compose up — exactly the pragmatic feature set you'd want for hosting private webhooks. It isn't reinventing scheduling (Airflow, Rundeck and hosted cron services already exist), but it's a tidy, usable package for teams that want a lightweight, self-hosted alternative with a Python SDK.
