Build or Skip

Build or Skip attacks the riskiest question in indie building: will anyone pay for this? It ranks 130,000+ websites by estimated monthly revenue — derived from observed payment-processor traffic, not self-reported MRR — with dedicated rankings for newly registered domains so you can spot products gaining traction in their first months. Filters cover category, domain age, DR and payment channel, and there's a side directory of 1,000+ high-DR backlink resources for when you do build.

The honesty is in the name: some ideas deserve a skip, and revenue evidence beats both instinct and Twitter hype. Public tip-jar data as a ranking signal is a clever source most competitors don't touch.

Who it's for: indie hackers and small teams choosing between build ideas, niche-site operators hunting proven markets, and anyone tired of "validated" ideas that turn out to be a founder's optimism. $19/month or $190/year. As with any estimation tool, treat the numbers as directional — the trend line matters more than the exact figure.
