How to cut costs when vibe-coding

Hello everyone,

Over the past few weeks, I’ve been playing around with a couple of vibe coding tools and with every single I used, I started hitting the same wall: I’d burn through credits and time because my prompts were incredibly basic and vague.

I would further realise that what I actually needed was a precise, production-grade, ready-to-use PRD before putting anything in an LLM.

To cater to this requirement for myself, I built a small side project — Specflow.ai.

It was built to take an app idea description and instantly create PRDs in Markdown and JSON. It auto-magically adds all the boring, yet essential elements.

The end product sits within vibe coding tools so that you can get working code with less prompts.

I decided to open it up for public use since it benefitted me a lot and might help a few people here. The model I use is super simple: pay per generation (no subscriptions) and you can keep and download the PRDs.

I would love to hear any feedback from fellow builders, and you guys can also try it: specflow.ai

Please note, that this is an MVP. I plan to add more much needed documents for app development.
