Building ArbHunter: the anti‑hype toolkit for ad arbitrage

Hey Indie Hackers — I’m Bill, founder of ArbHunter.

I built ArbHunter because most ad‑arbitrage advice online is hype and guesswork. I wanted a data‑first workflow that answers the questions I kept asking:

• Which niches are actually worth testing?

• What’s the realistic margin before I spend on traffic?

• What does a clean, non‑spam content setup look like?

So ArbHunter focuses on profitability before spend:

• Find profitable niches

• Estimate margins fast

• Test with real data (not vibes)

What’s live today:

• Niche finder

• Margin calculator

• Blog + playbooks (beginner‑friendly, no fluff)

What I’m working on next:

• Better traffic source comparisons

• Case studies with real numbers

• Tools to track RPM/CPC over time

If you’ve run arbitrage or are thinking about it, I’d love feedback:

• What’s the hardest part of the workflow for you?

• What would make a tool like this indispensable?

Happy to answer anything and take feature requests.
