Built Consent Mode v2 audit tool in 3 days for $32

Original: I Built a SaaS in 3 Days That Solves a $500 Problem for Free

Short summary

Author bootstrapped TagIntegrity in 3 days for $32 using no-code tools (Lovable, Supabase, Firecrawl) to solve Google Consent Mode v2 tracking breakage affecting 20-40% of websites. The free GTM/GA4/Consent audit tool now generates revenue with Pro ($79/mo) and Agency ($299/mo) tiers. Key lessons: launch broken and iterate in production, security requires deliberate engineering, and modern stacks compress SaaS development cycles dramatically.
