Async library for Kivy
Decision gist · record as of 2026-08-14
Yes. AsyncKivy is actively maintained, has zero known vulnerabilities, low install friction, and a permissive MIT license. It directly solves a real pain point in Kivy development—callback hell—and is well-tested on modern Python versions. Install it if you're building a Kivy app and want cleaner, more maintainable event-handling code.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later and an active Kivy application context to run event-driven code.
- Low friction: pure Python wheel with a single runtime dependency (asyncgui).
- Actively maintained with recent releases; tested on Python 3.10–3.13 with Kivy 2.3.

pip install asynckivy
import asynckivy as ak
async def task(button):
await ak.sleep(2)
await ak.event(button, 'on_press')
ak.managed_start(task(button))- Whether asynckivy integrates with Kivy's event loop automatically or requires manual setup beyond managed_start().

- Compatibility with Kivy versions other than 2.3.
What it is and what it does
AsyncKivy is a library that layers async/await syntax on top of Kivy's event system, eliminating the nested callback chains that make event-driven Kivy code hard to follow. Instead of binding callbacks to buttons or timers and manually unbinding them, you write async functions that await events and delays in a linear, top-to-bottom flow. It depends on asyncgui for its core async machinery and integrates with Kivy's clock and event system.
The library provides primitives like ak.sleep() for time delays, ak.event() to wait for button presses or property changes, ak.wait_any() for timeout-like patterns, and ak.wait_all() for coordinating multiple concurrent waits. You start an async task with ak.managed_start(), which handles lifecycle and cleanup. It's tested on Python 3.10–3.13 with Kivy 2.3 and carries no known vulnerabilities.
Use it for
- Simplify Kivy UI sequences: wait for a button press, then a timer, then a property change—all in one readable async function.
- Implement timeouts: use ak.move_on_after() to wait for an event with a maximum duration before moving on.
- Coordinate multiple events: use ak.wait_all() to ensure both a button press and a timer have completed before proceeding.
- Handle conditional waits: filter events with predicates (e.g., wait for button.x to exceed a threshold) without extra state variables.
- Nest async logic: compose complex event sequences by nesting ak.wait_any() and ak.wait_all() calls.
- Replace Kivy Clock callbacks: replace Clock.schedule_once() and event binding chains with linear async code.
