About

I’m an indie maker building small AI/devtools products. Currently working on Mermaid Online and launch/SEO tools for indie makers. Mostly here to discover useful builder tools, follow makers, and learn from good launches.

WebsiteReady - Find launch blockers before Google and users do

WebsiteReady checks your launch page before you promote it. Paste a public URL and get a GO, CONDITIONAL GO, NEEDS REVIEW, or NO-GO report with P0/P1/P2 issues, evidence, and developer-ready fix prompts. It checks crawlability, SEO basics, trust pages, broken launch signals, sitemap/robots issues, analytics hints, security headers, and AI discovery readiness including llms.txt and AI crawler policy.
