dbos 0.5.0a7

A Python framework for backends that scale

DBOS Transact Python

DBOS Python is under construction! 🚧🚧🚧 Check back regularly for updates, release coming in mid-September!

DBOS Transact is a Python library for building durable and scalable applications.

You want to use DBOS Transact in your application because you need:

• Resilience to any failure. If your app is interrupted for any reason, it automatically resumes from where it left off. Reliable message delivery is built in. Idempotency is built in.
• Reliable event processing. Need to consume Kafka events exactly-once? Just add one line of code to your app. Need to run a task exactly once per hour, day, or month? Just one more line of code.
• Built-in observability. Automatically emit OpenTelemetry-compatible logs and traces from any application. Query your app's history from the command line or with SQL.
• Blazing-fast, developer-friendly serverless. Develop your project locally and run it anywhere. When you're ready, deploy it for free to DBOS Cloud and we'll host it for you, 25x faster and 15x cheaper than AWS Lambda.
