Flask-APScheduler
Adds APScheduler support to Flask
Decision gist · record as of 2026-08-14
Yes, if you need basic APScheduler integration with Flask and can tolerate dormant maintenance. The package is stable and permissively licensed, but given the extended gap since the last release, verify compatibility with your Flask and APScheduler versions before committing. If you need active maintenance or support for very recent library versions, consider whether a more actively maintained alternative exists.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >= 3.8 and an underlying APScheduler installation (transitive dependency not listed in this fact sheet).
- Installation friction is high; the package has no runtime dependencies listed but has not been updated since 2023-11-07.
- Maintenance is dormant, so expect no active bug fixes or compatibility updates for newer Flask or APScheduler versions.

What it is and what it does
Flask-APScheduler is a Flask extension that wraps APScheduler, allowing you to define scheduled jobs and manage them through Flask configuration rather than imperative code. It loads job definitions and scheduler settings from your Flask app config, provides a REST API to query and control running jobs, and supports optional authentication for that API. It also integrates with Flask Blueprints for modular application structures.
The package is classified as Production/Stable and supports Python 3 only. However, it has been dormant since 2023-11-07 with no recent updates, so it may not be compatible with the latest versions of Flask or APScheduler. It has no explicit runtime dependencies listed in its metadata, suggesting those are handled transitively or assumed to be installed separately.
Use it for
- Run periodic background tasks (e.g., cleanup, reports, notifications) on a schedule defined in Flask config.
- Expose a REST API to view, trigger, or pause scheduled jobs without restarting the application.
- Manage job scheduling in a Flask application factory pattern using Blueprints.
- Implement cron-like scheduling for Flask web applications without writing raw APScheduler code.
- Authenticate and control job execution through a managed REST endpoint.
