Spin up populated test databases in seconds
We are building Tonic Ephemeral - a purpose built test database that is easy and fast to spin up (or down) based on your dev and test requirements. As engineers who worked on data at Palantir and Tableau, we've seen developers struggle to get isolated test databases when needed. We faced the same problem while we were building our core product at Tonic. Based on this, we decided to build something for ourselves and then realized some of our customers loved it too.

In plain words
Tonic Ephemeral is a test database tool designed to quickly provision and tear down isolated databases for development and automated testing. Built by engineers from Palantir and Tableau who encountered the challenge of accessing test databases during development, it addresses the infrastructure needs for short-lived testing environments. The tool focuses on speed and cost efficiency, allowing teams to spin up populated test databases on demand rather than managing persistent instances.

We are building Tonic Ephemeral - a purpose built test database that is easy and fast to spin up (or down) based on your dev and test requirements. As engineers who worked on data at Palantir and Tableau, we've seen developers struggle to get isolated test databases when needed. We faced the same problem while we were building our core product at Tonic. Based on this, we decided to build something for ourselves and then realized some of our customers loved it too. Today, we are sharing Tonic Ephemeral with the world. Briefly, Tonic Ephemeral manages test data infrastructure. In my experience, test data infrastructure is often very short-lived. We built Tonic Ephemeral with two main use cases in mind, optimized for speed and cost: -Test databases for automated testing -Test databases for development We launched today and would love to get some feedback from the HN community.
