So it's a DBaaS with a neat UI and GraphQL? https://www.prisma.io (formerly GraphCool) is similar.
With 8base front-end developers will be able to access data across legacy business systems through a unified GraphQL API. They can build business apps quicker and without developing custom server-side middlewares. Unlike a traditional BaaS, we have heavier focus on front-end tools (e.g. we have a UI kit for React) and enterprise features (identity, role-based permissions, document management, etc). We're not trying to be a BaaS for everything like Firebase or AppSync.
