Eden Stack

Full-stack development has long required juggling separate codebases, build systems, and deployment targets—one for web, another for mobile, yet another for the backend API. Eden Stack collapses this friction by offering a unified SaaS starter kit designed for teams building multi-platform applications where speed and code consistency matter.

The core promise is straightforward: developers get a single codebase that spans web and native mobile frontends, a type-safe API layer, and integrated AI capabilities—all with transparent, auditable source code. The "no lock-in" positioning is deliberate; founders can fork the project entirely, own the infrastructure, and modify anything without vendor dependency.

What distinguishes this offering is the depth of integration rather than breadth. The kit ships with over 60 UI primitives and 40 Claude-powered skills, which amounts to pre-built AI agent behaviors that developers can invoke from the chat interface. The demo screenshots show an AI assistant querying databases, triggering email sends via Resend, and scheduling delayed jobs through Inngest—actions chained together with Claude reasoning in the loop. This isn't a generic chatbot wrapper; the architecture treats Claude as a controllable execution layer tied to your application's own backend.

The type-safety story runs throughout. Eden uses Elysia for the API layer with a pattern called Eden Treaty to ensure types flow consistently between frontend and backend, reducing the runtime surprises that plague many full-stack projects. Authentication, business logic, and data schemas share definitions across all three tier—web, mobile, and API.

The included demo is functional enough to reveal the intended workflow. It showcases onboarding flows, API rate limiting, Stripe webhook handling, email template rendering, and session management—genuine infrastructure concerns rather than trivial examples. These patterns suggest the kit targets founders and small teams shipping real SaaS products, not tutorial projects.

Pricing follows a typical early-access model: the EARLYBIRD discount offers 50% off at $99 per license, though the full pricing structure beyond this limited cohort isn't detailed in the available content. The scarcity messaging (14 spots claimed) is standard founder playbook, but the pricing anchor itself is reasonable for a full-stack template with this level of integration.

Eden Stack is fundamentally a bet that developers would rather own and customize their SaaS foundation than stay locked into a platform. For teams shipping multi-platform applications and willing to maintain their own deployment, this approach trades platform convenience for sovereignty and flexibility.
