DartStream

DartStream is an open-source Dart-native framework for building backend services, Flutter and Flame experiences, and frontend-agnostic integrations around a stable set of engine, extension, and provider contracts.

The open-source project focuses on the framework foundation:

• the DartStream Standard Engine
• extension and provider contracts
• CLI tooling and project generation
• authentication, persistence, middleware, feature flags, reactive dataflow, AI, and ORM integration boundaries
• reference frontends and generated client patterns

DartStream SaaS is a separate managed Aortem product. It may use the open-source standard engine as a base, but hosted control-plane services, tenant operations, billing, provider credential management, and production SaaS operations are outside this open-source repository.

Core Capabilities

• Standard Engine: configuration, lifecycle, service registration, and extension management for DartStream applications.
• Provider Contracts: stable base packages for auth, persistence, storage, middleware, feature flags, reactive dataflow, AI, and ORM adapters.
• Feature Control: IntelliToggle is the official Aortem feature flag provider. flagd is the only other supported open-source feature flag provider lane.
• AI-Ready Extensions: ds_ai_base provides provider-neutral AI contracts so applications can integrate DartCodeAI or other current AI providers without hardcoding a provider into the framework.
• ORM Integration: ds_orm_base defines adapter contracts for current, actively maintained Dart ORM/data-mapping packages without making any ORM mandatory.
• Frontend Reach: Flutter and Dart are first-class. Nuxt and generated clients demonstrate non-Flutter frontend integration. Other examples are treated according to maturity.
