DBOS – Transactional Serverless for TypeScript Apps
Hello HN! We’re excited to show you DBOS, a transactional serverless SDK and platform that makes it easy to write fault-tolerant, observable, and scalable TypeScript applications. We’re a startup commercializing research we did at Stanford and MIT. (https://dbos-project.github.io/). The main idea behind DBOS is to store EVERYTHING about your application in the database. This gives you some unique features: * Reliable execution – Your program’s execution state is stored in the database, so if it’s ever interrupted, it automatically resumes from where it left off without…
In plain words
DBOS is a transactional serverless SDK and platform for building TypeScript applications. It stores application execution state in the database, enabling automatic recovery from interruptions without repeating completed work. The platform offers time-travel capabilities to rewind application state to any previous point. Designed for developers building fault-tolerant and scalable serverless applications, DBOS is based on research from Stanford and MIT.

In the maker’s words, at launch
Hello HN! We’re excited to show you DBOS, a transactional serverless SDK and platform that makes it easy to write fault-tolerant, observable, and scalable TypeScript applications. We’re a startup commercializing research we did at Stanford and MIT. (https://dbos-project.github.io/). The main idea behind DBOS is to store EVERYTHING about your application in the database. This gives you some unique features: * Reliable execution – Your program’s execution state is stored in the database, so if it’s ever interrupted, it automatically resumes from where it left off without repeating any work already performed. * Time travel – Every change to your program’s state is recorded in the database, so you can “rewind” time and restore the state of your application to what it was at any point in the past. For example, time travel debugging–take a tricky bug in production, rewind time, and reproduce it locally on your laptop. Today, we released our open-source SDK (https://github.com/dbos-inc/dbos-ts) and our free-to-try serverless platform (https://www.dbos.dev/dbos-cloud). We’d love for you to try them out and let us know what you think! Here’s a quick guide to get you started: https://docs.dbos.dev/getting-started/ We’re here to answer any questions!
