Why is meal planning still so hard in 2026?

I ve been thinking about this a lot while building my side project.

Cooking itself isn t that hard. But planning what to cook every week somehow feels unnecessarily complicated.

Recipes are saved in random places. Grocery lists live in another app. And meal planning usually ends up being a mix of notes, screenshots, and memory.

I built a free Excel add-in that replaces 80% of what people use VBA for

Hey Product Hunter!

I'm Federico, and I just shipped GridManager, a free Excel add-in that gives you a clean, professional sidebar to manage your spreadsheet data without ever touching a formula or navigating complex menus.

The problem I was solving: Excel is powerful, but managing data in it feels clunky. Adding rows means scrolling to the bottom, editing means finding the right cell, validating means writing formulas. It shouldn't be this hard.

What GridManager does:

I built a tool that calculates the real cost of a 3D print (not just filament)

One thing I noticed when selling 3D prints is that most people only calculate filament cost.

But a print actually includes a lot more:

electricity
printer wear
maintenance
failed prints
markup

So I built a small tool called 3D Print Calculator that calculates the real print cost automatically.

I built a MCP gateway to help teams host MCP servers remotely

I ran into an issue while working on a project to centralize MCP servers for an organization - some tools break as the client and server don't share a file-system.

To solve this, I wrote an opensource adapter that you can self-host.

Most AI Tools Give You an Answer. Munger Would Call That Dangerous

Ask any AI chatbot "why is my user retention dropping?" and you'll get a decent list of suggestions. Organized, readable, and almost entirely useless for hard problems.

Why? Because complex problems don't yield to a single perspective. Charlie Munger spent a lifetime proving this. His answer the one that helped build Berkshire Hathaway into one of the greatest investment machines in history was the Latticework of Mental Models: a cross-disciplinary framework that forces you to triangulate truth through multiple lenses before reaching a conclusion.

FunBlocks AIFlow brings this philosophy into an AI-powered thinking tool. It doesn't just answer your question. It thinks about your question the way Munger would.

Over 10000 devs used our API for AI interfaces - now we are open sourcing it

AI agents got smarter. Their interfaces didn't. Ask an AI to analyze your sales pipeline and you get three paragraphs. You should get a chart.

We've spent the last year building Generative UI used by 10,000+ developers, and the biggest lesson was that JSON-based approaches break at scale. LLMs keep producing invalid output, rendering is slow, and custom design systems are a pain to wire up.

So we built OpenUI Lang, a rendering spec inspired by code rather than data formats. LLMs generate it reliably the way they generate well-formed functions. The benchmarks: up to 67% fewer tokens, 3x faster rendering, streaming-native, and safe by default (no arbitrary code execution).

Today we're open sourcing it. Model-agnostic, framework-agnostic, design-system agnostic.
Show us your support by starring or contributing to our repo - https://github.com/thesysdev/openui
