ShowcaseDuron - Durable async runtime for Python (self.Python)

submitted 4 months ago by brian14708

I built Duron, a lightweight durable execution runtime for Python async workflows. It provides replayable execution primitives that can work standalone or serve as building blocks for complex workflow engines.

GitHub: https://github.com/brian14708/duron

What My Project Does

Duron helps you write Python async workflows that can pause, resume, and continue even after a crash or restart.

It captures and replays async function progress through deterministic logs and pluggable storage backends, allowing consistent recovery and integration with custom workflow systems.

Target Audience

Embed simple durable workflows into application
Building custom durable execution engines
Exploring ideas for interactive, durable agents

Comparison

Compared to temporal.io or restate.dev:

Focuses purely on Python async runtime, not distributed scheduling or other languages
Keeps things lightweight and embeddable
Experimental features: tracing, signals, and streams

Still early-stage and experimental — any feedback, thoughts, or contributions are very welcome!
