FAQ

What is it?

It's a database server that is adapted to run as a low cost "stateless" web service in the cloud.

Why does it exist?

Most cloud providers allow you to run HTTP stateless service for free, but database servers, even cheapest ones, are at least a few $ per month.

How does it work?

1. On startup, it downloads database files from cost-efficient storage, like S3
2. Then it runs database engine on it
3. When service is going to be redeployed files are send back to S3

Which cloud providers are supported?

For now it's GCP Cloud Run only, AWS and Azure are on the way.

Is there any SDK?

Unfortunately not for now. However, it should be straightforward to implement a basic client.

Should I use it in production?

No.
