Hi, my name is Stefan and I keep daydreaming about opening a caf and wondering if the numbers would actually work.
So I built Caf Empire, a business simulation where you run a caf , set prices, hire staff, manage stock and suppliers, take loans, and all your decisions generate real financial statements (P&L, balance sheet, cash flow).

There's a Student Mode aimed at people learning accounting or entrepreneurship, where it adds quizzes built from your own numbers, "explain this" tips on every line, and CSV export for Excel/Power BI, but also Tycoon mode for more advanced functionalities like franchising, opening a roastery, rivals, market share, reviews & reputation, seasons, etc.

A few weeks ago I shared Reporting SaaS here, and the feedback was clear: nobody wants "automated reports", people want to stop losing money without noticing.

So that's what it does now. Every Monday, a Shopify store owner gets a PDF report that explains why sales moved. And when discounts, refunds or cancellations run well above normal, the report puts a dollar figure on the loss, names the cause (the discount code, the most refunded product, the main cancellation reason) and suggests one action. If there's no clear cause, it doesn't invent one.

Over the past few years, I ve been working on e-commerce and payment infrastructure.

As we integrated more payment providers, we kept running into the same problem:

Integrating one payment gateway isn t particularly difficult. The real challenge begins when a business has multiple websites, multiple payment providers, and multiple merchant accounts that all need to be managed together.

Launching Zalcro later this week and wanted to share it here first. I built it to solve a problem I kept running into: AI builds that start very well but fall apart when things have to connect. For me, everything goes great until I add auth, or a second feature, and suddenly I'm fixing one bug and breaking another.

Zalcro is a pre-build planning tool for vibe coders. You tell it your idea, answer a few questions, and it generates a blueprint, sequential prompts for Lovable, Bolt, Replit, etc or a dependency-aware ticket backlog for Cursor and Claude Code. It takes the guesswork out so your AI coding tool builds with a plan from the start.

Would love feedback from anyone building with AI tools.

Hey, I'm Yohann. 19, first SaaS, launched today. Every milestone post looks the same: crop the dashboard, post the PNG, then someone asks if the number is real. A screenshot takes ten seconds to fake. MotionMRR is the video instead. Read-only key (Stripe, Lemon, Polar, Dodo, Paddle) a motion video of the revenue the provider actually recorded. 16:9, 9:16, 1:1. If you're at $0, it doesn't invent a curve. First video is free, no card. Not a leaderboard. Just the file you'd drop in the tweet. https://www.producthunt.com/prod... Would you swap the screenshot on your next update, or is the PNG still enough?

Hey everyone, we're Dennis and Matias, 2 devs from Germany and Chile.

a walk with my son made me want more than a folder of photos. i wanted to keep the places and moments together, as one story.
i'm Alperen, co-founder of iz, building it with Tuna in Istanbul. iz lets you leave a photo postcard, a note, music or a book memory at the place where you are. you can keep traces private or share them.
we've added collections so traces from a walk, a trip or an ordinary day can sit together on a map. you can give a collection a cover and a description, then share it as an image or a link.
a question for people who take photos on their walks: would you revisit a map of your memories, or would a simple photo album still be more useful? what would make you save your first collection?
if you'd like to try it, iz is on iOS and Android, free to download with optional in-app purchases: https://iz.city/en/
i'd especially appreciate feedback on the first-memory experience. no need for a big trip an ordinary day counts too.

I've been working on Free Invoice Generator, a simple tool for freelancers and small businesses who just want to create a professional invoice without having to learn complicated accounting software.

While building it, I kept coming back to a simple question:

What are the features people actually care about when creating an invoice?

For me, the essentials seemed to be:

I recently built Clariola, a tool that helps businesses run SEO audits. I initially targeted small and medium-sized businesses, but I m finding it difficult to reach and convert them.

This made me realize that many business owners may not actively look for SEO tools or fully understand the problem they solve. I m now considering targeting agencies and freelancers who manage SEO or marketing for multiple clients.

For those building SaaS products: how did you validate your target market before building? Do agencies and freelancers usually pay for tools like this, or would they expect a different workflow?

I m building APEX PULSE PRO, an AI fitness and performance product.

The idea is not to make another workout tracker or a chatbot with fitness prompts.

I want the product to feel like one connected system where the athlete, training decisions, feedback, and AI all work together.

A big part of that is APEX Core - the visual and interactive center of the product. It is meant to communicate state and make the experience feel more alive, rather than just adding more dashboards and metrics.
