UseThatApp

A marketplace for developers to monetize browser-based apps.

June 14, 2026 Why build UseThatApp?

We built UseThatApp because the bottleneck for many developers is no longer just building software.

With AI-assisted coding, React, Python, Dash, Streamlit, Vercel, Render, Supabase, and similar tools, developers can now build useful browser-based apps faster than ever.

But many of those apps never become real products.

They stall after the build phase because commercialization becomes a second product:

  • app pages

  • pricing

  • subscriptions

  • billing

  • customer access

  • support

  • trust

  • distribution

  • getting in front of users who may actually pay

UseThatApp is my attempt to solve that problem.

The goal is to create a marketplace where developers can publish useful browser-based apps and monetize them as subscription products without rebuilding the entire business infrastructure from scratch.

We are currently looking for founding developers with working or near-deployable browser-based apps.

Best fit:

  • useful web app

  • clear audience

  • specific problem

  • hosted online or close to launch

  • developer wants a monetization path

This is early, so I’m looking for serious feedback from builders, especially developers who have useful tools but have not fully commercialized them yet.
