Welcome to DBOS!

What is the DBOS SDK?

The DBOS SDK is a Typescript framework built on the database that helps you develop transactional backend applications. DBOS fully embraces the power of your application database, helping you write backend applications that are reliable by default. It runs your Typescript functions as database transactions, guarantees they run once and only once for each request, and orchestrates them into workflows so reliable that if your server restarts, they resume exactly where they left off.

You should build your next backend application with DBOS because:

  • It's simple. Write your business logic using serverless functions. Store all your data in Postgres—we'll manage the connections and transactions for you.
  • It's reliable by default. Even if you have to reboot your server, your workflows will always resume from where they left off. Reliable message delivery is built in. Idempotency is built in.
  • It's made for DBOS Cloud. Starting early next year, you can deploy any DBOS application to DBOS Cloud, our new cloud platform built on our revolutionary, scalable, and secure cloud-native operating system.
