I recently built halupedia - a funny site that hit 300k+ users in few weeks and #1 on hacker news. It was amazing project, which costed me $300+. Since halupedia uses a lot of AI I paid a lot for the bill, fortunately I'm fine thanks to donations and resigning from many planned features.

It inspired me to built wattfare - just like BYOK it let's user bring their own AI budget to the site.

It works like OAuth, user just clicks a single button, has ability to limit or revoke access for a website any time and has great developer experience (at least I think so ).

In the future I'm going to add multiple ways for the user to pay for usage, ideally would try to make it possible to connect openai/anthropic subscriptions to wattfare, but it's not going to be that simple - if you have some thoughts about that, please let me know.
