Snaplet Preview Databases Github Action

Deploy Snaplet preview databases filled with production-accurate data in no time.

With this action, you can finally enjoy fully isolated and stateful preview environments. Get a new preview database filled with production-accurate data anytime you need it and plug it into your Jamstack hosting platform of choice like Vercel.

By default, the preview database will be populated with data from your latest Snaplet snapshot.

Learn more about creating snapshots in our docs.
