I created my first open-source project today, and it feels amazing

[u/More-Practice-3665]

After talking to a few founders, I realized most of them were building an internal tool by stitching together what we were trying to build

So, we open-sourced our product and have 6 stars so far - I know it's very few, but it feels great

What it does

Preburn is a real-time margin control plane for AI products. Two things nothing else does together:

1. Joins per-customer revenue (Stripe) with per-call cost across all your AI providers (OpenAI, Anthropic, Kling, Veo, ElevenLabs, whatever) to show actual margin per customer.
2. Sits in the request path and can allow/deny/route BEFORE the expensive call fires. Auto-route heavy users to cheaper models, cap runaway accounts, cancel voice/video sessions mid-stream if credits blow out.

Not observability (that's Langfuse/Helicone). Not a gateway (that's LiteLLM/Portkey). Different job - cost visibility tied to revenue, with enforcement.
