I built LaunchScore to stop myself from building things nobody wants
I'm a solo founder with a small portfolio of SaaS tools. My process for most of them looked like this: get excited, build for weeks, launch to crickets, repeat.
I knew validation mattered but never had a clean workflow for it. Scattered tools, no way to compare ideas, and no real signal beyond gut feeling.
So I built LaunchScore: describe your idea, AI generates a landing page, you share it, and real signups + an Interest Score tell you which ideas are worth building before you write a line of code.
Launching today. Free to start, no credit card required.

Would love feedback from anyone who's been through the "built it, nobody came" cycle.

Great project! I'm also launching LinksWatcher today to help affiliates track 'Zombie Pages' via AI. It's a tough day at #139 but we're hanging in there! Good luck with your growth.
This hits too close to home.
“Get excited → build for weeks → launch to crickets” is basically the unofficial founder curriculum.
I like the angle of measuring real signups instead of just asking people “would you use this?”
Two questions I’d think about:
How do you ensure traffic quality?
An Interest Score is powerful, but bad traffic can distort validation.
Do you help founders interpret the signal?
Because many of us struggle more with decision-making than with data collection.
This could be really valuable if it becomes not just a scoring tool, but a validation framework.
Congrats on shipping.
Great questions. The Interest Score factors in visitors, email signups, feedback ratings, and conversion, weighted by a confidence factor that scales with traffic. So a single signup from one visitor won't inflate the score. On interpreting the signal, that's a direction worth exploring. Right now the score helps you rank and compare ideas, but a "here's what to do next" layer would add a lot. Appreciate the feedback.
This resonates. I’ve definitely been in the build for weeks -> launch -> silence loop.
One thing I’d challenge a bit: signups alone don’t always equal real demand. People are generous with emails, especially for AI tools.
Have you thought about adding a lightweight commitment signal? Even something small like pre-orders, pricing visibility, or a question like Would you pay $X for this? might separate curiosity from intent.
I like the idea of comparing ideas in one place though. The meta-layer of validation is interesting.
You're spot on about signups vs real demand. Right now the score weights email signups heavily (20x visitors) but also pulls in feedback ratings and a confidence factor that requires meaningful traffic before those signals carry full weight. Adding something like pricing visibility or a "would you pay $X" question would be a good next step to separate curiosity from intent. The comparison angle is what I'm most excited about too. Being able to rank multiple ideas by real engagement signals instead of gut feel changes how you pick what to build.
Congrats on the launch — looks really solid!
If you’re thinking about validating your idea in a more real way, there’s an interesting setup where you can submit it into a live competition ($19 entry, winner gets a Tokyo trip, prize pool grows with entries).
Might be a fun way to test actual commitment vs just interest.
