The BYOK Advantage

Why pay $99/mo when you can pay $0?

We don't mark up data prices like competitors. With Bring Your Own Key (BYOK), you connect directly to free tiers.

Scale insanely cheap: Once you exhaust free tiers, buy Serper credits directly. $1 = 1,000 Searches (~20,000 Leads!).

What Agency Owners Say

"The math is insane. I plugged in my Serper free tier API key and scraped 25,000 real estate leads in a day. Best AppSumo purchase this year."

Frequently Asked Questions

BYOK stands for "Bring Your Own Key". While we provide monthly system credits (e.g., 30k on Tier 2), you can input your own API keys for Serper, SerpApi, or Gemini. This allows you to use their free tiers directly or pay them at cost price ($1 for 1,000 searches) bypassing all SaaS markups!

No. To keep the lifetime deal sustainable for everyone, your internal system credits reset to your Tier limit (e.g., 30,000) on the 1st of every month.

Yes. If you purchase through AppSumo, you are fully covered by their 60-day money-back guarantee. Direct website purchases are covered by our 7-day technical refund policy.
