Zalcro is the pre-build planning tool for AI app builders. Jumping straight into prompting usually leads to a doom loop where the AI loses context and breaks your app. Zalcro solves this by mapping out your architecture before you begin. It generates a build-ready plan so your AI knows exactly what to do. Whether you use Lovable, Replit, Cursor, or Claude Code, Zalcro gives you step-by-step prompts you paste directly or connect via MCP. Build better. Plan before you prompt,

Hey Product Hunt 👋
I'm David, founder of @Zalcro After 10+ years in product management, I’ve seen the exact same pattern repeat. When you skip planning at the beginning, things falls apart near the finish line.
Today, AI lets anyone build. But jumping straight into building usually leads to that frustrating wall where things go wrong, and you break three features trying to fix one tiny bug. You burn through credits and you're tempted to start all over.
I built Zalcro to fix this. It plans your app from the start and provides you a blueprint your AI can actually follow.
How it works
Describe your idea. Just explain what you want to build in plain language
Answer a few questions: Zalcro gives you suggestions to easily nail down the requirements.
Get your blueprint: It generates your architecture, a visual diagram, and a Prompt Pack with step-by-step prompts.
Copy, paste, and build: Paste the prompts into your AI tool one after the other. Happy building!
Zalcro also fits right into your existing stack. It connects directly via MCP to Cursor, Claude Code, and Codex, and you can export all your blueprints to your computer or Google Drive.

I'd love to hear from you! What has been your biggest headache when trying to build a product with AI coding agents?
I'll be hanging out in the comments all day to answer questions and hear your feedback!
@davidoduk how does the direct MCP connection to claude code actually work? does it feed the whole architecture doc at once or chunk it out by the sequenced tickets?
@mohsinproduct Great question! The MCP connection makes the architecture doc and tickets available as resources, just like any other document in the project folder. Claude Code pulls them when you tell it to. You can ask Claude to read the full architecture doc for big-picture context, or just the specific ticket you’re working on.
To answer your question, my biggest headache is the AI forgetting a decision I made twenty prompts earlier and quietly rewriting something that was working fine. I gotta say the idea of handing it an architecture diagram plus prompts in order sounds like it would stop a lot of that. Curious how it holds up on a messy idea instead of a clean todo app.
@founder92 Thanks Nela! That memory gap is the root cause of so many build failures. Zalcro fixes it by giving the AI a stable reference point before you write a single line of code.
On messy ideas, it starts with clarifying questions to figure out exactly what you’re building, then gives you options with recommendations before generating anything. Try it with something totally half-baked, no login required, just drop your idea on the home page and see what comes out. Would love your take!
The way I have always done which worked great for me is by simply discussing my overall idea with Claude Code like a brainstorming session, leading to an architecture discussion, possibly some evals on sample data when that's available to see if our hypothesis stands among other things. There is a lot of back and forth clarifying things for each other. A lot of times Claude Code recommends things I would have never thought about. At times it can also sound silly. However, this is the most important phase in my process and Claude starts writing code later when I am convinced with everything. Even in that case I am never locking down an architecture knowing that things can change as we build and discover things along the way. I have been perfectly fine with this approach. My only issue with Claude is not remembering clear instructions, getting stuck on certain solutions by just doing lazy tweaks over and over when something doesn't work instead of thinking of and implementing something totally different and so on.
How would Zalcro help improve the experience for someone like me in a major way? I am using the world's best coding agent (arguably) with their best models. Why should I switch to Zalcro for the initial planning phase? What's making Zalcro better than Claude Code at this?
@davidoduk this looks to be a great way to increase success and accuracy of the build. Do all the planning and specification design upfront to guide the agent down the path you want. Best of luck with the launch.
@codeandsea Thanks Brent, that’s the whole idea! A lot of vibe coders skip the planning step and end up with "almost working" code. Doing it upfront keeps the agent on track because it has something to hold it accountable. Appreciate the support! 🙏
