Built 9 free, no-signup SEO tools so we'd stop paying $100/mo just to audit our own sites.
Indexability, canonical, sitemap, meta tags, broken links, hreflang, PageSpeed - each runs an instant check on any URL, no account.
The reasoning behind each one:

Deindexing is the quietest way to lose traffic - nothing 404s, pages just slip out of Google's index and the rankings go with them.
The 8 causes we see most (a stray noindex on a shared template, canonical-to-redirect, soft 404s, orphan pages...) and how to catch each one:

Most SEO crawlers moved to monthly subscriptions. We didn't want to pay every month just to re-audit our own sites, so we built one with one-time pricing instead.
Site-wide technical SEO audit + real PageSpeed, $9-49 once, credits never expire. Free to try a site.

How do you convert files without ever uploading them?
File Converter Free (one of our products, 100K+ users/mo) runs 30+ format conversions 100% in the browser via WebAssembly. Files never touch a server. It even works offline as a PWA.

Why we built our own website build system instead of using an off-the-shelf one.
Kalenuxer is our open-source, Node.js incremental build system: only rebuilds what changed, 15+ languages built in. On large sites that's minutes to seconds.
