Validation
Validation tools are for validating demand before writing any code — the kind of work every indie hacker eventually hits and would rather not build from scratch. 6 tools are listed here, each picked and written up individually rather than pulled from an affiliate feed. Carrd is usually the first one people try: ship a one-page site in an hour to see if strangers will hand over their email before you write a single line of backend code. LaunchList takes a different angle — pay once, not monthly, for a waitlist with built-in referral virality — built for solo founders testing one idea, not a SaaS. And Prelaunch.com is worth a look too: makes people put a refundable deposit down for your idea — actual money beats a survey answer as proof anyone wants this. Every listing below includes the actual tradeoff, not marketing copy, so you can pick based on what you're building instead of what ranks highest in a sponsored roundup elsewhere.
