Show HN: LLM-powered webapp to build LLM-powered webapps

A developer has launched an LLM-powered webapp builder that proxies OpenAI and Anthropic calls, charging end users 2x the token cost and sharing 80% of the profit with the app creator. The system uses Abstract Syntax Trees to have the LLM write transformation code for targeted code changes, and the project runs in a Docker container for easy deployment. The goal is to let developers earn revenue proportionally to user token usage without managing a separate revenue model.

Hey all,

The goal is to earn on token margins for LLM calls when you build an AI-powered webapp. I proxy OpenAI and Anthropic calls so that when you deploy a site to a subdomain, your users token usage will be tracked. I charge 2x the token cost to the end user, where the webapp creator gets 80% of the profit and I get 20%. The idea is to ramp your revenue from simple AI apps directly with your popularity and real usage

I've built this over the last 3 years. The system behind it is kind of crazy: I use Abstract Syntax Trees and have the LLM write AST transformation code to implement code changes to files. I haven't benchmarked it in a while, but last time I did, it cost more in tokens but produced more targeted code changes (as compared to other agent harnesses). I wrote a blog post about this idea when I first built it: https://codeplusequalsai.com/static/blog/prompting_llms_to_m...

Your development project is run inside a docker container, and you can publish it to make it public and get users, and hopefully earn revenue. The real big goal is to make it easier to build small LLM webapps and not worry about revenue model: as users grow (and token costs grow), so does your revenue, proportionally.

Do please tell me what you think about the idea and my implementation!
