Reach developers at the exact moment they’re fixing their site.

Shipleak is free, has no signup, and runs 65checks against anyone’s URL. Sponsors are what pay for that. Every report is a permalink people share, so a slot keeps working long after the scan.

Target by the stack we detect

Every scan fingerprints the framework. You can buy a slot that only appears on reports where we detected your users’ stack — so a Next.js tool is shown to people who just ran a scan on a Next.js site.

  • Next.js
  • Astro
  • Remix
  • SvelteKit
  • Nuxt
  • Vercel
  • Supabase

This keys off what we measured about the site being scanned — not who is reading. There is no cookie, no pixel, and no profile of the visitor, because there is no tracking on this site at all.

What we won’t do

  • Sponsors never affect results. The scan engine has no access to who is paying us. Buying a slot cannot change a finding, a severity, or a score.
  • Nothing appears inside a findings list. Slots live in the rail and are labelled Sponsored. A paid placement next to a severity rating would read as a sponsored finding.
  • No scripts, no tracking. Slots are text rendered from our own config. We can’t give you an impression pixel or a retargeting tag — we audit sites for exactly that, and ours has to pass.
  • Links are marked rel="sponsored". Correct disclosure. If you need a dofollow link for SEO, this is the wrong product.
  • Nothing goes up unreviewed. Every sponsor is checked by a person before it appears — the link, the copy, all of it. Your paid month starts when it goes live, not when you pay, and if we can’t run it you get a full refund.

Founding sponsors

Shipleak is new, and the honest version of that is: traffic is early and the price reflects it. Founding sponsors keep that rate as traffic grows. Send us your product and a one-line description — the form has the price and the slots that are still free.
