Co-founder here: Great question! Yeah, the biggest difference is that DBOS doesn't require a centralized workflow server, but does all orchestration directly in your functions (through the decorators), storing your program's execution state in Postgres. Implications are: 1. Performance. A state transition in DBOS requires only a database write (~1 ms) whereas in Temporal it requires a roundtrip and dispatch from the workflow servers (tens of ms -- https://community.temporal.io/t/low-latency-stateless-workflow/1643 https://community.temporal.io/t/low-latency-stateless-workfl...). 2. Simplicity. All you need to run DBOS is Postgres. You can run locally or serverlessly deploy your app to our hosted cloud offering.
