Welcome to DBOS!

With these DBOS solutions, you can easily build scalable, reliable, and secure TypeScript applications:

DBOS Transact - An open-source TypeScript framework for developing transactional applications with built-in once-and-only-once code execution.
DBOS Cloud - A transactional serverless platform for deploying DBOS Transact applications to the cloud with built-in high performance, scalability, fault tolerance, and database time travel.

You want to build your next backend application with DBOS because:

It's reliable by default. If your workflows are interrupted for any reason, they will always resume from where they left off. Reliable message delivery is built in. Idempotency is built in.
It's simple. Write your business logic with serverless functions and either self-host them or deploy them to DBOS cloud in minutes. Store your data in Postgres—we'll manage the transactions for you.
It makes debugging easy. With our time travel debugger, you can "rewind time" and replay any DBOS Cloud trace locally on your computer, exactly as it originally happened.

To get started in less than five minutes, check out our quickstart!
