A
About PlanetScale

PlanetScale is a serverless MySQL-compatible database platform built on Vitess, the same technology that powers YouTube's database infrastructure. It provides developers with non-blocking schema changes, branching workflows similar to Git, and horizontal scaling without the typical operational overhead of managing a distributed database. The platform is designed for development teams who want the reliability of MySQL with modern DevOps workflows, including deploy requests and schema review processes. PlanetScale handles sharding, replication, and failover automatically, making it particularly appealing for applications that need to scale quickly without a dedicated database administration team.

About Fly.io

Fly.io is a platform-as-a-service that runs applications in lightweight micro-VMs (using Firecracker) close to end users across a global edge network. It allows developers to deploy full-stack applications, databases, and services to dozens of regions worldwide with minimal configuration using a CLI-driven workflow. The platform is particularly well-suited for developers who want the control of infrastructure without the overhead of managing Kubernetes or traditional cloud VMs. It supports Docker containers and various runtimes, making it flexible for different tech stacks. Fly.io differentiates itself by combining the simplicity of a PaaS with the power of deploying actual virtual machines at the edge.
