DBOS Transact Python Library

DBOS provides an ultra-lightweight Python library for durable execution, enabling fault-tolerant workflows and queues built on PostgreSQL (or SQLite by default). It allows developers to add resumable execution to applications using simple function annotations, eliminating the need for separate workflow orchestrators or task queue systems. As of version 2.18.0, it offers features like exactly-once execution, scheduled jobs, and built-in observability. The library is actively maintained with frequent updates and is suitable for building reliable backend services, data pipelines, and AI agents.
