White-label API testing SaaS kit – launch your branded tool in days for $20/mo.
Solo indie hackers building API testing tools can't sustainably price their products because developers demand free tools while infrastructure costs keep rising.
TestBrand offers a customizable frontend dashboard and backend, ready for rebranding, handling all heavy infra like test execution and storage. Indie hackers deploy under their domain, charge customers $10-50/mo sustainably with zero backend dev. Low fixed costs enable profitable pricing despite free alternatives.
