SaaSYa gives your coding agent the instructions, design system, documentation, and production-ready foundation to build the SaaS you describe.
AGENTS.md + DESIGN.md + the complete SaaS foundation
No platform to learn and no prompt library to manage. SaaSYa turns the repository itself into your agent’s source of truth.
Get the complete, versioned starter as your own source code.
Tell your coding agent what the product should do in ordinary language.
The agent reads the system, adapts the design, implements, verifies, and explains.
The instructions, visual contract, and system documentation live with the code. Every supported harness is directed to the same source of truth.
AGENTS.md
Operating system
Autonomy, safety, architecture, validation, and definition of done.
DESIGN.md
Design contract
North star, tokens, typography, components, states, and visual QA.
docs/
Knowledge base
Setup and system-level guidance the agent consults before changing code.
The reusable platform layer is already organized so the build can focus on your product’s unique workflow.
DESIGN.md
Before producing screens, the agent establishes or adapts the product’s visual contract. A feature that works but feels inconsistent is not considered complete.
The agent owns the system
SaaSYa is the reusable system extracted from products that needed to authenticate users, charge money, run AI, and keep operating after launch.
Pay once, keep the source, and use the foundation for your own products or client work.
Lifetime access
Everything your agent needs to turn the foundation into a real product—without renting another platform.
