Cruxproof

Cruxproof tests a startup idea against live competitors and real prices before you spend months building it. Key features: • Finds the core claim your idea depends on and tests it first • Searches live for competitors, including ones that roundups miss • Pulls prices from vendor pages and labels secondhand prices • Scores weak spots using low-star reviews and repeated complaints • Runs a simple margin calculation you can check line by line • Builds a working MVP and a ready-made plan to validate with real people. Each report is built from live sources, and every claim is linked and rated so you can verify it yourself. The verdict is honest, and it can recommend not building at all. Research results can be wrong, so check the linked sources before making decisions. Validations start at $5, and MVP builds are paid. Built for solo founders, indie hackers, and product teams who want evidence before committing time or money. It suits anyone who needs a quick competitor scan, a pricing comparison, or a clear go or no-go call on a new product concept.
