As answered by people managing Is My Landing Page Valid and GitHub Codespaces.
Is My Landing Page Valid's answer
Most landing page tools either just critique your page or need traffic and weeks of A/B testing. Is My Landing Page Valid gives you an instant verdict and then rebuilds the page for you. In about 20 seconds you get a 0-100 conversion score on a fixed 7-factor rubric, the specific leaks costing you signups, a concrete fix for each, and an AI-generated, improved version of your actual page. No account, no traffic required. It is also deliberately blunt and honest: it never invents fake social proof or fake conversion numbers.
Is My Landing Page Valid's answer
Three reasons. First, it doesn't just grade your page, it rebuilds it, so you leave with a better page, not just a list of problems. Second, zero friction: no signup, a free score, and a one-time unlock at $2.90 instead of a monthly subscription. Third, it's honest by design, it grades against a fixed rubric tied to real elements on your page and refuses to fabricate proof or promise a conversion percentage it can't know. It's built for speed and clarity, not for locking you into a platform.
Is My Landing Page Valid's answer
Founders, indie hackers, makers and small marketing teams who are getting traffic but few signups, and want fast, specific feedback on why. People who ship their own landing pages and don't have a conversion specialist on call.
Is My Landing Page Valid's answer
The founder kept shipping landing pages that looked fine but barely converted, and could never tell exactly why. Friends were too polite to give real feedback. So he built the blunt, specific critique he wished he had: an AI that audits a page the way a conversion specialist would, scores it, and shows precisely what to fix, then rebuilds it. It's grounded in established CRO frameworks (LIFT and the MECLABS conversion heuristic) so the feedback is principled, not vibes.

Next.js 15 (App Router) and TypeScript, Tailwind CSS, deployed on Vercel. The audits and the page rebuild run on Anthropic's Claude models. Data is stored in Upstash Redis, payments via Stripe, and transactional email via Resend.
Is My Landing Page Valid's answer
It's an early-stage product, so there are no enterprise logos to name yet, and I'd rather not invent any. Today it's used by indie founders, makers and small teams auditing their own landing pages. You can see real pages it has scored on the public teardowns and leaderboard at ismylandingpagevalid.com/teardowns.
