baas2

baas2 is a term used in technology with no single, universally accepted meaning. It is most often encountered as an informal contraction for Backend as a Service version 2.0, denoting a second-generation family of cloud-based backends designed for mobile and web applications.

A baas2–style platform typically provides a set of modular services that can be wired together by developers, including user authentication, data storage and querying, file storage, push notifications, and serverless functions. It usually offers an API-first interface, with SDKs for multiple platforms and real-time data synchronization; architectures may support GraphQL or REST APIs and emphasize scalability, security, and multi-tenancy. The goal is to reduce custom backend development and enable faster app iteration.

Because the term is informal, baas2 may also refer to specific projects or libraries that use "baas2" in their name or as a code name. In such cases, the precise features and scope depend on the project's documentation. In others, baas2 is used as shorthand in discussions about next-generation BaaS platforms or serverless backends.
