# Codalio > Requirements-to-code AI app builder: spec-first delivery with governed agents, PRDs, technical scope, and exportable full-stack code — not demo-first vibe coding. Codalio inverts prompt-to-code. It engineers a coherent PRD and technical scope from plain English, then orchestrates agents against that living specification. Built for founders and enterprises moving past vibe coding toward **agentic engineering**. ## Core product pages - [Home — founders and innovators](https://codalio.com/): spec-first AI app builder entry point. - [AI App Builder](https://codalio.com/ai-app-builder): requirements-to-code vs vibe coding and prompt-to-app tools. - [AI MVP Builder](https://codalio.com/ai-mvp-builder): investor-ready MVP scope and planning. - [AI PRD Generator](https://codalio.com/ai-prd-generator): structured PRDs from ideas. - [Technical Scope Generator](https://codalio.com/technical-scope-generator): PRD to delivery-ready technical scope. - [AI App Builder with Source Code](https://codalio.com/ai-app-builder-with-source-code): ownership and no vendor lock-in. - [Enterprise agentic engineering](https://codalio.com/enterprise): governed agentic engineering for regulated buyers. ## Guides & resources - [MVP checklist for founders](https://codalio.com/mvp-checklist-for-founders) - [How to write a PRD for an MVP](https://codalio.com/how-to-write-a-prd-for-an-mvp) - [Technical scope template](https://codalio.com/technical-scope-template) - [Source code ownership for AI app builders](https://codalio.com/source-code-ownership-for-ai-app-builders) ## Competitor comparisons (prompt-to-app vs requirements-to-code) - [AI app builder alternatives hub](https://codalio.com/alternatives) - [Lovable alternative](https://codalio.com/alternatives/lovable) - [Replit alternative](https://codalio.com/alternatives/replit) - [Base44 alternative](https://codalio.com/alternatives/base44) - [Bubble alternative](https://codalio.com/alternatives/bubble) ## Blog — agentic engineering & vibe coding - [From Vibe Coding to Agentic Engineering: Why AI-Generated Product Specs Matter](https://codalio.com/blog/from-vibe-coding-to-agentic-engineering/) - [The MVP Is Dead: How One Founder Ships an Enterprise-Grade Product on Day One](https://codalio.com/blog/mvp-is-dead-your-virtual-engineering-team/) - [Agentic Engineering Isn't AI That Codes Faster](https://codalio.com/blog/agentic-engineering-isnt-ai-that/) - [Your Harness Is Only As Smart As Your Spec](https://codalio.com/blog/your-harness-is-only-as-smart-as/) - [The Prompt Is Not The Plan](https://codalio.com/blog/the-prompt-is-not-the-plan/) - [Build Fast, Break Faster?
