●●●BangerSolve My ProblemShip It

Plugs the gap between Stripe and OpenAI bills—finally see which customers are actually profitable.

Strengths
  • •Solves a real pain point (no existing tool maps API costs to customer P&L)
  • •Practical what-if modeling using public benchmarks (MMLU-Pro, GPQA) to find cheaper models without quality loss
  • •Minimal SDK integration (npm/pip/REST) means adoption friction is low
Weaknesses
  • •Requires active Stripe account; not immediately useful for pre-revenue or non-Stripe companies
  • •Cost simulator only covers major vendors (OpenAI, Anthropic, etc.); niche model providers excluded
Category
SaaS
Target Audience

SaaS founders and engineers using AI APIs with multiple customer tiers

Post Description

I built MarginDash because I couldn't answer a basic question: which of my customers actually make me money after AI costs? My Stripe dashboard showed revenue going up. My OpenAI bills showed costs going up faster. I had no way to connect the two at the customer level. MarginDash is a few line SDK integration (TypeScript, Python, or REST) that tracks model usage per customer and connects it to revenue — either through Stripe sync or by passing revenue directly in the API call. You get a per-customer P&L showing revenue, cost, and margin.

A cost simulator lets you pick any feature, swap the underlying model, and see projected savings. Models are ranked by intelligence-per-dollar using public benchmarks (MMLU-Pro, GPQA, AIME) so you can find cheaper options that aren't actually worse. Budget alerts email you before a customer or feature blows past a threshold.

The pricing database covers 100+ models across OpenAI, Anthropic, Google, AWS Bedrock, Azure, and Groq with daily updates — so cost calculations stay accurate without you maintaining a spreadsheet. The SDK only sends model name, token counts, and customer ID. No prompts, no responses.

Solo founder, built the whole thing for $239.72 in AI costs (wrote about that too). Currently free while I get feedback — would love to hear what you think, especially about the cost simulator.
