pre.dev is a browser-based AI software architect for planning and building software products. It helps founders and product teams turn an idea into a clear roadmap and technical architecture, even without deep engineering expertise.
Product planning and system architecture
Describe your product idea and pre.dev structures it into an actionable plan, covering:
- Modules, services, and APIs
- Frontend and backend components
- Suggested tech stack, dependencies, and scaling considerations
From idea to prototype-ready specs
pre.dev supports both new and existing products. You can import a repository and use the AI to:
- Create detailed specifications (Deep Spec)
- Prepare a solid foundation for implementation
- Align work with an internal team or external developers
Keeping code agents aligned
For teams using coding agents, pre.dev provides Architect API and MCP (Research Preview) to keep agents aligned with architecture and requirements, reducing rework and improving code quality.
