I keep building shit and then need to sell it.

So I made a marketplace for that: vibemarketplace.io

That's it. That's the whole story.

You can list your project, optionally connect Stripe or Lemonsqueezy so buyers can see real revenue, and close with escrow so nobody gets screwed. If you've got stuff sitting around making money that you want to sell, use it. If you're looking to buy cashflowing projects, use it.
