Stop wondering what to build on weekends.

What we're building

Vote for the one you'd actually pay for below. We build the winner first.

1. Skills-as-Legos Engine

What it is: Tells you what to build by recomposing the AI skills that already exist into novel product concepts nobody's combined yet.

For you if: You have the skills to build, but not the idea.

"Here are 7 things no one has built — each made from skills that already exist on marketplaces you already use."

2. Marketplace Crawler + Recommendation API

What it is: Indexes every AI skill / MCP / plugin marketplace into a capability graph. Tell it your idea; it says "compose these existing skills instead of building from scratch."

For you if: You already know what to build and want to ship 10x faster by not reinventing wheels.

"Don't rewrite. Compose. Get a shortlist of existing skills that cover 80% of your idea."

3. 5-Minute Pretotype Generator

What it is: Describe your idea. Get a deployed landing page, a fake-door sign-up form, and a smoke-test ad — live in 5 minutes. Measure real demand before you write a line of backend.

For you if: You start building before checking if anyone wants it.

"Idea → deployed pretotype in 5 minutes. Kill bad ideas before they cost you a month."

4. Idea-to-Validation Pipeline (skill pack)

What it is: A bundle of AI skills that runs your raw idea through market sizing, competitor scan, assumption mapping, and pretotype design — the full discovery workflow, packaged for any agent runtime.

For you if: You want the structure but not the spreadsheet.

"Install the pack. Run discover my-idea. Get a go/kill/iterate verdict and a plan."

5. Side Project Radar

What it is: Continuously watches GitHub, Hacker News, Reddit, Product Hunt, and X. Surfaces underserved niches ripe for a side project — scored by competition density × effort-to-MVP.

For you if: You want a weekly feed of "here's where the gap is" instead of scrolling for inspiration.

"A weekly digest of underserved niches, scored for side-project fit. Stop scrolling, start building."

FAQ

What if my favorite idea isn't on the list?

Tell us in the survey. We'll consider it for a future pack.

When does something ship?

When the data says one of these is worth building. Could be 4 weeks, could be never. We'll tell you either way.

Is this open source?

Undecided. Vote "I'd pay" if you'd pay; tell us in the survey if you'd only use it free.

Who are you?

A developer who got tired of abandoning side projects three weekends in.
